The olive 109

Adana Topağı: the olive cultivar that needs the least coldThe lowest chilling requirement among cultivars tested: 346 hours, 234 chill units. Why that matters as winters warm, and its 6-gram fruit.
Akhisar Domat Olive: the specification behind stuffed olivesRegistered in 2010. The certificate sets calibre separately for each product form — 170-290 for stuffed, 110-260 for cocktail. One cultivar, different sizes.
Akhisar Uslu Olive: the measured specification of a black table oliveRegistered in 2010 as a designation of origin. The certificate defines the Uslu cultivar in figures — and corrects a published error: the flesh ratio is 85.17%.
Antalya Tavşan Yüreği Olive: a registration named after the shape of its fruitRegistered in 2018. Fruit and stone are heart-shaped; picked green, its oil runs 9-20.2%, rising to 25% at black maturity.
Arbequina olive: Spain's oil varietyThe mainstay of super-high-density planting. Small canopy, small fruit, early bearing — the variety that changed modern olive growing.
Aydın Memecik Olive: grafted on wild rootstock, a tree that yields for a centuryRegistered in 2021. The certificate ties the cultivar's key trait to longevity: grafted on wild rootstock, Memecik yields economically for 80-100 years and can then be rejuvenated.
Aydın Yamalak Sarısı Olive: a table fruit reaching 11 gramsRegistered in 2021. At 6-11 g the fruit is among Turkey's largest table olives. It is propagated by grafting onto wild rootstock and harvested in late September.
The Ayvalık (Edremit) olive: one variety, two names19-20.66% of the tree stock, second after Memecik. 25% oil. Green maturity only between 15 and 30 October; black maturity after 15 November, among the latest.
Belluti oliveBelluti is a recorded variety of south-eastern Anatolia. No measured pomological data published.
Butko oliveButko is a recorded variety of the Black Sea. No measured pomological data published.
Büyük Topak Ulak oliveBüyük Topak Ulak is a recorded variety of the Mediterranean. Described in the source.
Büyükbelen Tekir Olive: a table olive born from grafting two cultivarsRegistered in 2024. The Eşek (Ödemiş) cultivar is grafted onto Uslu seedling rootstock. The flesh does not soften after processing, giving a long shelf life.
Coratina olive: Italy's oil varietyAmong the highest-polyphenol varieties in the world. Distinctly bitter and pungent — the oil that gives blends their backbone.
Geographical Indication Olives and Olive Oils of TurkeyTürkiye's registered olive and olive oil geographical indications: which product, which locality, under what conditions — and what registration means.
The Domat olive: the cultivar behind stuffed olives, in numbersDomat, Turkey's largest table cultivar: 7.96 g fruit, 89% flesh, a 552-hour chilling requirement. Why stuffed olives are always made from it, the disagreement over oil content, and why it is never planted alone.
World olive varieties: from Picual to KalamataAbout 1,200 cultivars exist; commercial weight sits in a few dozen. Picual, Arbequina, Koroneiki, Kalamata, Frantoio — compared with Türkiye.
The Edincik Su olive: the third black-table cultivarOne of the three cultivars widely processed as black table olives in Turkey, alongside Gemlik and Uslu. The cultivar of the Bandırma area.
Edincik Olive: high water content makes it a table oliveRegistered in 2024. The certificate gives one reason why the cultivar goes to the table: high water content. Its volatiles include 1.5-25% ethyl acetate.
Edremit Gulf Green Scored Olive: a registration that defines altitude and slopeRegistered in 2014. The certificate draws the boundary topographically as well as administratively: 50-250 m altitude, 5-6% slope. Debittering is entirely natural.
Which table olive variety is best?The leading varieties for black and green table olives, measured fruit weights, and how curing affects quality.
The Erkence olive: the cultivar that sweetens on the treeErkence accounts for 3.5% of Turkey's olive trees. It is the Aegean's earliest-ripening cultivar and has a property with few equivalents anywhere: the fruit loses its bitterness on the tree, without brine.
Eğriburun olive: characteristics, oil content and growing areasThe lowest oil content on the list (17%) but the highest flesh ratio (89%) — a pure table variety.
Frantoio olive: Italy's oil varietyThe emblem of Tuscan olive oil. A balanced, aromatic, moderately bitter oil, and the most widely exported Italian variety.
Gaziantep Green Olive Pastry: a registration that turns a recipe into a ruleThe only prepared dish among olive geographical indications. The document binds the half-moon shape, the 14-15 cm diameter, the filling gram by gram, the sheep breed, and inspection twice a year. The olives used are oil-type, not table.
The Gemlik Olive designation of origin: what the certificate saysTurkey's first registered olive (2005, no 76). The certificate defines four districts, three cultivars, four curing methods and seven size grades — all of them binding.
The Gemlik olive: small fruit, six times the fleshTurkey s only olive cultivar with a geographical indication: 3.7 g fruit, a 6.4 flesh-to-pit ratio, 29-30% oil. Self-fertility measurements, chilling requirement, and why it is still picked by hand.
Gölvala oliveGölvala is a recorded variety of the Black Sea. No measured pomological data published.
The Halhalı olive: Hatay's oil cultivarHalhalı accounts for 2.2% of Turkey's olive trees, the main oil cultivar of Hatay and Mardin. The measured self-sterility of Yuvarlak Halhalı and what it means for orchard planning.
Which provinces in Turkey grow no olives?Forty-six of Turkey's 81 provinces have no commercial olive production: 36 absent from the statistics, ten reporting zero. Samsun has 13,000 trees and no crop.
Which type of olive is better?Table or oil, green or black — choosing a variety by purpose, with a short regional map.
Hatay Halhalı Olive: what long sunshine hours do to phenol contentRegistered in 2023. The certificate ties the high phenol content (322-525 mg/kg) directly to long sunshine hours, and defines two separate debittering methods.
Hojiblanca olive: Spain's oil and table varietySpain's third-largest variety and genuinely dual-purpose: it goes to black table olives and to oil alike.
Hursuki oliveHursuki is a recorded variety of south-eastern Anatolia. No measured pomological data published.
Kalamata olive: Greece's table varietyThe world's best-known table olive. Almond-shaped, purplish-black fruit, and a name that is a protected designation of origin.
Kalem Bezi olive: characteristics, oil content and growing areasTied with Kilis Yağlık for the highest oil content on the list (31%), but with a better flesh ratio.
Kan Çelebi oliveKan Çelebi is a recorded variety of south-eastern Anatolia. Described in the source.
Do olive trees grow on the Black Sea coast?Ten Black Sea provinces produce 865 tonnes between them, 83 per cent of it in Artvin. Trabzon gets 98 tonnes from 36,000 trees; Samsun none from 13,000. The obstacle is humidity, not cold.
Karamürsel Samanlı Olive: low bitterness earns it the name “sweet olive”Registered in 2024. Its oleuropein content of 6-8% is low, so it debitters quickly and is locally called the sweet olive. Its skin is 0.2-0.4 mm.
Karamürsel Su olive: characteristics, oil content and growing areasThe largest fruit on the list: only 140 per kilo. Marmara's own distinctive table variety.
Kilis Yağlık olive: characteristics, oil content and growing areasOne of Türkiye's highest oil-yielding varieties at 31%. Small-fruited and purely for oil — 560 fruits per kilo.
Kiraz olive: characteristics, oil content and growing areasAkhisar's early table variety. Low in oil, but early maturity makes it the season's first olive to market.
Koroneiki olive: Greece's oil varietyThe backbone of Greek olive oil. Very small fruit, very high polyphenol content, and one of the three super-high-density varieties.
Leccino olive: Italy's oil varietyFrantoio's blending partner. A softer profile with notable cold and disease tolerance.
Manzanilla olive: Spain's table varietyThe world's most widely planted green table variety and the international standard for stuffed olives. It is grown in Türkiye too.
Marantelli oliveMarantelli is a recorded variety of the Black Sea. Described in the source.
Olive growing in Marmara: the home of the table oliveThe table olive's home is not the Aegean but Marmara: 80% of the region's crop is Gemlik. The reason is climate.
Mavi oliveMavi is a recorded variety of south-eastern Anatolia. No measured pomological data published.
Melkebazi oliveMelkebazi is a recorded variety of south-eastern Anatolia. No measured pomological data published.
The Memecik olive: Türkiye's oil varietyBetween 19% and 45% of the tree stock. 24-25% oil, 88% flesh. Green maturity in early October, two months after Gemlik.
Memeli olive: characteristics, oil content and growing areasThe highest flesh ratio on the list at 89%. Low in oil, but with one of the smallest stones.
Milas Ekşili Olive: a table olive lightened with lemonRegistered in 2024. The aroma of lemon and olive oil is pronounced, and the astringency of other table olives is absent. Total phenols at least 135.38 mg/100 g.
Milas Oil-Cured Olive: the one table-olive registration with measurementsFive of the six registrations are olive oils. This is the one table olive, and its certificate gives fruit dimensions, flesh-to-stone ratio and flesh firmness in figures.
Milas Çekişke Olive: the season's first table olive, picked in SeptemberProtected as a geographical indication since 2021. The cultivar is Memecik, but the difference is timing: picked in September, green and by hand. The stage at which oil content is still low is exactly right for the table.
Mission olive: United States's table and oil varietyAmerica's historic variety: carried by the Spanish missions, it built California's black table olive industry.
Nizip Yağlık olive: characteristics, oil content and growing areasThe southeast's main oil variety and one of the rare self-fertile cultivars on the list — it crops even without a pollinator.
Olea europaea: the botany of the olive treeThe olive's scientific name and classification, why its leaves are silver, its floral structure, the layers of its fruit, its root system and lifespan — and how the wild oleaster relates to the orchard olive.
Otur oliveOtur is a recorded variety of the Black Sea. Described in the source.
Patos olivePatos is a recorded variety of the Black Sea. Described in the source.
Picual olive: Spain's oil varietyThe single largest share of world olive oil production. High oleic acid and polyphenols, a pungent and stable oil.
That white film on your olive brine: mould or yeast?The white layer that forms on home-brined olives is usually not mould but a film-forming yeast — though that does not make it harmless. There are visible criteria for telling them apart. Together with the pH and salt ceilings the Turkish Food Codex sets for brine, here is what can be saved and what has to be thrown out.
Samanlı olive: characteristics, oil content and growing areasThe local table variety around Lake İznik — Gemlik's neighbour, with a different fruit structure.
Sarı Haşebi olive: characteristics, oil content and growing areasHatay's local table variety, virtually unknown outside the region and part of Kuseyr Plateau olive growing.
Sarı Ulak olive: characteristics, oil content and growing areasThe eastern Mediterranean's table variety. The lowest flesh ratio on the list (72%) — a large stone, yet it holds its ground.
Sat oliveSat is a recorded variety of the Black Sea. No measured pomological data published.
Saurani olive: characteristics, oil content and growing areasHatay's dual-purpose variety: 29% oil with 87% flesh — one of the most balanced combinations on the list.
The Difference Between Black and Green OlivesNot two different trees but the same fruit at two different moments. So why do they differ in taste, texture and nutrition?
How are black table olives made? Natural ripening versus blackeningTwo different black olives sit on the shelf: ripened on the tree and brined, or picked green and blackened by oxidation. Both lawful, but not the same product.
Table Olive VarietiesFrom Gemlik to Kalamata, Manzanilla to Castelvetrano: the world's best-known table olives and what each is good for.
Table Olives: Types, Curing and How to ChooseFrom green to black, cracked to dry-cured: how table olives are made, chosen and kept.
Fraud in table olives: lye, artificial blackening, copper sulphate — how and whyNatural debittering takes 6-12 months. Which of the methods that cut it to days are lawful, and which are fraud? Lye, artificial blackening, copper sulphate — and six ways to spot fake olives.
Where is quality lost in table olives?Variety choice, harvest technique, fermentation control, sterilisation and the pre-packing check are each a separate point of loss. The structural problem is scale and inspection.
Tarsus Sarıulak Olive: the same cultivar behaving differently in one placeThe certificate measures Sarıulak in Tarsus and generally, side by side: it flowers a month earlier, ripens a month later, and has larger fruit and more flesh.
Tavşanyüreği oliveTavşanyüreği is a recorded variety of the Mediterranean. Described in the source.
Where do olives grow in Türkiye, and where don't they?What limits the olive is frost, not a provincial border. Where it grows in Türkiye, with cold thresholds and altitude limits.
Which is Turkey's best-quality olive?Quality criteria and measured values for Turkey's main olive varieties — fruit weight, oil content and intended use.
Uslu olive: characteristics, oil content and growing areasAkhisar's black table variety. Overshadowed by Gemlik, yet holding its own market.
Yamalak Sarısı: the local table cultivar of AydınA local cultivar of Aydın counted among Turkey's most important table olives, and the subject of a phenotypic characterisation study.
Which olive varieties have the highest oil content?Kalem bezi and Kilis yağlık lead at 31 percent, with Gemlik just behind at 29-30. Measured oil content for 40 varieties — and what the figure does and does not tell you.
Yağ Çelebi olive: characteristics, oil content and growing areasDespite the name, its 21% oil puts it low on the list; its large fruit also serves the table.
How are green table olives made? Three methods, three resultsGreen olives cannot be eaten off the tree; the bitterness must be removed. The difference between Spanish-style, natural brine and scored methods sets time, texture and taste.
What are green olives, and how do they differ from black?Green olives are not a separate variety but the same fruit picked early. What sets the colour, why pick green, and where the difference from black begins.
The Olive TreeOlea europaea: botany, lifespan, root and leaf structure, monumental trees. The identity of the Mediterranean's emblematic tree and how it lives.
The Olive Harvest: When and HowEarly harvest or late? The timing of picking directly determines the oil's acidity, polyphenols and yield.
How to Store Olives: From an Opened Jar to a Winter BatchHow long does an opened jar last, what to do when the brine runs low, how to keep dry-cured olives? Why mould forms and what the white film actually is.
How Are Olives Cured?An olive straight from the tree is inedible — it is bitter. In water, in salt, in lye or scored: the methods that remove the bitterness, and how long each takes.
The Olive Sector in Turkey: Structure, Exports and ChallengesProduction, exports, business structure and price: the Turkish olive sector in figures, and where the chain breaks.
The Olive Calendar: The Olive Year Month by MonthWhen to prune, when it flowers, which olives are picked when — the year of the tree and the grower, month by month.
How long does an olive tree live?There are plenty of "thousand-year-old olive" signs and almost no measurements. Counting annual rings does not work on olive: when ten experts in five laboratories were given the same samples, their ring counts differed by more than 44%. Radiocarbon dating carries its own trap. So does the tree have a real age limit — and what does it mean that Crete's famous monumental olive turns out to consist of two different genotypes?
Are my olives spoiled? Mould, bulging lids and softeningA white film on brine is not always mould. But a bulging lid is not debatable: discard it unopened. How kahm yeast differs from mould.
How to store olive spread: homemade, opened jars and freezingHomemade olive spread is kept in the fridge in a clean glass jar, covered with a thin layer of olive oil, and eaten within about a week. For opened shop-bought jars, the time on the label applies. Spread with garlic or fresh herbs should never be left at room temperature.
Where do olives grow in Turkey? The picture in 45 provincesThe Aegean alone produces half the national crop; ten Black Sea provinces together manage 865 tonnes. In 46 provinces there is no commercial production at all.
Olive wood: why spoons and not beams?At 0.86 g/cm³ air-dried it is denser than walnut, yet its modulus of elasticity of 4,444 N/mm² is less than half walnut's. It resists crushing but not bending.
Olive and Olive Oil GlossaryOleuropein, lampante, pomace, malaxation, designation of origin… Short, verifiable definitions of olive and olive oil terms.
Olives and Olive Oil: Frequently Asked QuestionsDoes the fridge test work, what separates extra virgin from riviera, can you fry with olive oil? The 18 most common questions, answered briefly.

The Olive: Tree, History, Production and FutureThe botany, history and uses of the olive tree; current production figures worldwide and in Turkey, provinces, varieties and the sector's future — with tables.
Chilling requirement in olives: which variety grows where?The olive must spend time below 7.2°C in winter. Adana Topağı needs 346 hours, Domat 552. Unmet, some years bring no crop.
Products from OliveTable olives, oil, pomace, leaf and soap: what is made from each part of the tree, and what each is good for.
How do you reduce the salt in olives?Draining the brine does not remove the salt — it has worked its way into the flesh. A Spanish study measured that soaking in water cuts sodium by 61-72%, but the same process also carries away up to 78% of the potassium and softens the fruit. The legal salt ceiling for table olives is 8% by weight, and the "low salt" claim requires no more than 4 grams per 100. Which method works how well, and what does each one give up?
Olive Oil Soap: How It Is Made, Its Types and How to ChooseHow saponification works, why curing takes months, and how to recognise genuine olive oil soap.
Zoncuk oliveZoncuk is a recorded variety of south-eastern Anatolia. No measured pomological data published.
The Çakır olive: a cultivar that asks for a thousand hours of coldReported alongside Ayvalık and Domat with a 1000-hour chilling requirement — the group most at risk as winters warm.
The Çekişte olive: the Aegean's lesser-known oil cultivarÇekişte accounts for 1.5% of Turkey's olive trees — more widespread than Domat or Uslu, yet a cultivar whose name is almost never heard.
The Çelebi olive family: seven types, two separate geographiesÇelebi is not one variety but a family name. Tesbih Çelebi yields above 22 percent oil while Hamza, Yuvarlak and Yün Çelebi stay under 18. Measured values for seven types.
The Çelebi olive: the green table cultivar of İznikGrown around İznik in Bursa, Çelebi is a green table cultivar. Its oil content is lower than Gemlik's — which is no drawback for a table olive.
Rooting olive cuttings: 30 of 133 wild olives made itIn Hassa, Hatay, 133 wild olive genotypes were rooted from cuttings and only 30 cleared the 50% threshold. Rooting depends on the genotype, not the technique.
The Çilli olive: large fruit, low chilling requirementAt 6.90 g it ranks among the large-fruited cultivars, and sits in the low chilling-requirement group — second only to Adana Topağı.
How to recognise a good table olive — and what to check when buyingIs the colour mottled, the brine clear, the calibre stated? Concrete checks for buying table olives, whether Gemlik is an oil or table variety, and how to store them at home.

Analysis and sector 43

Fourth in the world with 25 registrations — but what are they doing?Türkiye is fourth in the world with 25 olive oil GIs. Yet exports fetch $3.17/kg — the product is still priced as a commodity.
Alternate bearing: one year yes, one year noOlive oil output can swing from 40,000 to 200,000 tonnes. Why alternate bearing happens, how it breaks prices and exports, and how its amplitude can be reduced.
Was it six times? Seven years of the table olive gapHow many times the oil price does a table olive fetch? Over seven years the ratio ranged 1.43 to 3.46, never below 1.
The same olive, six times the price: the quiet advantage of table olivesHow much more does the same fruit fetch as a table olive than for oil? Measured over seven years of exchange data: 1.43 to 3.46 times.
Tree to shelf: the olive oil value chain in six stopsFrom fruit on the tree to bottle on the shelf: how much the price multiplies at each step, and where the added value stays.
The energy burned at the field edge: olive pruning residueOne olive tree yields 33.6 kg of prunings a year. Across 177.8 million trees that is 6 million tonnes of residue and 54.11 PJ of energy — equivalent to 1.57 billion m³ of natural gas.
What does a kilo of olives cost? The cost sheet of 152 Aegean farmsLand rent is 37.70% of cost, harvest 16.90%. In table olives 73% of processing cost is rejected fruit; in oil, 94% is the fruit itself.
Exchange volume is not the harvest: what the 2023 record actually recorded10,597 tonnes registered in 2023, down to 3,227 the next season. Harvest collapse or a change of channel? The data cannot tell them apart.
How to read olive oil exchange pricesThree exchanges, three averages for the same product: 201, 254 and 308 lira. In Nazilli, trades from 132.79 to 225.00 in a single day. What an exchange price measures, and why date and volume matter more than the average.
Twenty trees per decare, or 250? The density debate15-25 trees per decare in Türkiye, 200-300 in super-intensive systems. Payback falls from 15 years to 8 — but the densest is not the most profitable.
Rain in Andalusia, prices in Aydın: how Spain's drought set the price in TürkiyeSpain makes 40% of the world's olive oil. Its output halved in 2022/23 and Türkiye's euro price went from €2.70 to €6.95.
Early harvest: expensive or valuable? The arithmetic of yieldBelow 18% yield the raw material costs more than the bulk price. Early-harvest oil needs a 43% premium to break even.
The nameless olives of southeast Anatolia: Mardin, Şırnak and the pollinator problemKumçatı and Derik genotypes beat Ayvalık and Gemlik on flesh ratio. Yuvarlak halhalı sets only 0.43% of its flowers with its own pollen.
The economics of caliber: how fruit size triples the price160 TL at caliber 18, 55 TL at caliber 41. Fruit size is price — and the cooperative pays 16% above the exchange average.
Vegetation water and pomace: olive oil's waste problemProcessing 1.5–2 million tonnes of olives yields 1 million tonnes of vegetation water and 1 million tonnes of pomace. Waste, or resource?
Kilis: the structure is solved, the soil is notKilis is the one place in south-eastern Anatolia to have finished the institutional job: a union, an integrated plant, a geographical indication. Yet 100% of 49 soil samples are iron-deficient.
A demand for 50 lira per litre: what the numbers sayThe Edremit Chamber of Commerce has called for at least 50 lira per litre in support for olive oil producers. We check the price claim behind that demand against registered exchange trades.
Marmarabirlik purchase prices: what the grower actually receives in MarmaraThe 2025/2026 season: 160 ₺ for calibre 18, 55 ₺ for calibre 41, 53 ₺ for oil fruit. Size alone changes the price 2.9×, and the union buys down to calibre 41 where the market stops at 28.
Olive oil enterprises in Mut: a field studyMore than 4% of Turkey's olive production comes from Mut. In a 2025 study of 14 enterprises, raw material quality ranks last among their problems. All eight websites of firms wanting to export are monolingual.
Oleotourism: a grove's second incomeWhat is olive oil tourism, how does it work elsewhere, and why has it not developed in Türkiye? Oleotourism, from the literature.
Olive oil trade in the Ottoman Empire: Britain the buyer, the crop the price25,627 tonnes exported in 1889 at 23.54 lira a tonne; 9,022 tonnes in 1882 at 42.89. The crop-price inverse held a century ago too.
The olive grove beside the factory: Bursa soils measured43 PCB congeners measured in 7 Bursa olive groves: 5.82-18.71 ng/g against a 200 ng/g limit. No serious pollution — but the point near the steel works reads three times the rural one.
How war destroys an olive grove: denial of access does more than the bombAn olive grove is not an annual field: first fruit takes 4-8 years, full yield 20-25. War's damage is therefore generational, not seasonal. We read the picture in Lebanon and Palestine through the tree's own biology.
The table olive sector: 461 registered, 8,000 unregisteredTurkey has become the world's leading table olive producer, with a record $255.3m in 2024-25 across 117 countries. Yet only one enterprise in twenty is registered.
The gap between extra virgin and riviera is only 4% at wholesaleAt wholesale, extra virgin is only 4-23% dearer than cooking oil; the seven-year average is 13%. The shelf gap comes from packaging.
Is Turkish olive oil cheap? Fourteen months against EuropeTurkish and European olive oil prices compared in one currency. How wide is the gap, and is it currency or market?
Türkiye leaves an off year as Tunisia enters one: opposite phase in the MediterraneanTürkiye's crop fell 35% in 2025-26, yet table olives rose and the drop was far from even: Aydın −8%, Bursa −50%. Tunisia is in the opposite phase, down 40% for 2026-27. The two countries sit in opposite halves of the cycle, and that shapes the bulk olive oil market.
Structural problems of Turkish olive growing157 million trees but 5% of world output: low yield, old trees, harvest mechanisation, missing data, the support gap and informality.
What temperatures can the olive withstand?Ideal 15–20 °C, an upper limit of 40 °C (with irrigation), a lower limit of −7 °C. Temperature thresholds, chilling requirement, and the climate risk of production narrowed to four varieties.
How do olive growers rank their own problems?A face-to-face survey with 64 growers in İzmir: input costs, an average holding of 45 decares, unirrigated land, and cooperative membership that rises with scale.
From olive to oil: the price gap, 2019-2026The gap between a kilo of olives and a kilo of oil, measured from exchange registrations. Why it widens, and who gains.
Who protects the olive tree? Three layers, from the IOC to Law 3573We have cited the International Olive Council in 23 articles without ever saying what it is. The three orders that protect the olive: trade standards, landscape conventions, and Türkiye's 1939 Law No. 3573.
Olive groves and mining: the legislative record from Law 3573 to Law 7554A dated record of the rules opening olive groves to mining: Article 20 of Law 3573, the March 2022 regulation and its annulment by the Council of State, and Law 7554 in force since 24 July 2025. Impact estimates are set against the national total and one circulating figure is fact-checked.
Felling an olive grove: the arithmetic of a ten-year decisionThe ten-year cost of clearing a grove for another crop: establishment, years to bearing and forgone income, per decare.
Solar panels above the grove: energy without cutting trees?In Spain, 5,150 solar modules were raised four metres above a working olive grove without removing a single tree. The height is set not by the trees but by a harvester that opens to 3.5 metres. A University of Córdoba model puts joint output at 789 kg of oil and 891 MWh per hectare.
Did olive oil go up 13.5 times, or 1.6 times?Up 13.5 times in lira, 1.6 times in euros. The same 1,257 registrations, each converted at its own day's ECB rate.
Olive Oil Prices: Week 35 of 2026Turkish exchange prices, European producer prices and exchange rates side by side: extra virgin at 300 TL/kg in Edremit, Spain's national average €3.52/kg.
Olive Oil Prices: Week 36 of 2026Week 36 of 2026: Turkish exchange prices, European producer prices and exchange rates side by side.
Olive Oil Prices: Week 37 of 2026Week 37 of 2026: Turkish exchange prices, European producer prices and exchange rates side by side.
The profitability problem in olive oil exportsTurkey sold to the US at $3,492 a tonne while the world average was $4,235 - the furthest supplier and the cheapest. The EU tariff wall, the Tunisia comparison, and the method none of 17 exporters knew.
The real price of olive oil: the inflation-adjusted calculationThe lira price rose 11.5-fold, inflation 7.6-fold. The real increase is 1.56-fold — and it matches the euro-based calculation.
Two thirds of our exports are table olives: the $260 million pictureIn 2025-26, 66% of exports were table olives and 27% oil. Average unit value $3.17/kg — the added value sits inside the packaging.
Climate change and the olive: the tree survives, but will it crop?The olive is drought-hardy but works in narrow bands. 85% of Türkiye's groves are unirrigated, 75% on mountainous land.

Cultivation 30

Arbequina IRTA-i18: the clone behind super-high-density olive grovesIRTA-i18, developed from Arbequina by clonal selection, was chosen for super-high-density groves. What early bearing, mechanical harvest and a low 459-hour chilling requirement actually mean.
Does an ungrafted olive tree bear fruit? Wild olives, seedlings and graftingAn ungrafted olive tree does bear fruit, but usually small, thin-fleshed and low in oil. Neither the wild trees known in Turkey as delice nor seedlings grown from a stone carry the variety of the parent tree. How to tell, what grafting gains, and why wild olives are still valuable.
How many kilos of olives does one tree yield?Türkiye averaged 13.5 kilos per tree in the 2025/26 season. But the average describes nobody's grove: 20.3 kilos in İzmir, 3.5 kilos in Şanlıurfa. The same grove does not repeat its own number either — across six major provinces, per-tree yield went from 22.6 kilos one season to 8 kilos the next. Here is what the figure actually depends on, and how to place your own tree against it.
Which olive variety is the most productive? Regular crops, early bearing and alternate bearingThere is no single "most productive olive". Productivity depends on whether a tree bears regularly every year, how early it starts cropping and pollination. In our variety data, Picual and Frantoio are high and regular, Gemlik is early with low alternate bearing, while Kalamata, Hojiblanca and Memecik swing between on and off years.
Should harvested olives be carried in crates or in sacks?The cheapest decision of the harvest season is also one of the decisions that sets the grade of the oil. Three separate defects in the International Olive Council's vocabulary are defined directly by how the fruit was held after picking — and all three describe what a sack does.
What is an olive harvest net, and how do you choose one?A net spread under the tree does two jobs at once: it keeps the fruit off the soil and it speeds up collection. Olives that touch the ground give higher-acidity oil, and fruit left on the ground feeds the next generation of olive fruit fly. Here is how to choose a net — material, weight, size — and how to lay it.
What to do for olive trees after harvest: a November-to-March care guideThe work in the grove does not end with the olive harvest; next year's crop is prepared in exactly these months. From collecting fallen fruit and protecting harvest wounds to region-specific peacock spot sprays, the right pruning time, autumn feeding and winter soil work, here is what needs doing after harvest.
Organic olive growing: what a four-year trial foundA four-year organic vs conventional trial at Kemalpaşa: no yield difference, 11.5% higher gross margin for organic, lower peroxide value, but higher fruit oil content under conventional management.
Should I switch to organic? A decision guide for olive grovesA four-year trial found no yield difference and put organic 11% ahead economically. But where does the real cost of switching lie, who does it suit, and how do you fight the fly without chemicals?
Caring for an olive tree in a pot: container, soil, watering, light and winterOlive trees can live in pots, but they do not forgive two things: too much water and too little light. A wide pot with drainage holes, a free-draining mix, watering once the top layer dries and at least six hours of direct sun are the basic rules. Expecting fruit indoors is usually pointless without a cool winter.
Choosing certified olive saplings: labels, documents and varietyLabel colour shows the certificate class: blue certified, yellow standard. The difference is traceability, not quality. The support gap is 930 lira per decare. Four questions that settle variety choice.
Do olives grow in cold regions?Olives survive -7 °C, lose shoots at -12 °C and the trunk below -15 °C. Yet Artvin delivers Turkey's highest yield per tree: microclimate beats the map.
Cold-hardy olive varieties: Gemlik, Ayvalık and the other candidates in the dataIn our variety data, Gemlik, Ayvalık, Coratina, Picual and Hojiblanca are recorded with high cold adaptation or hardiness; Kalamata, Leccino, Memecik and Domat are medium, Frantoio moderately sensitive and Saurani low. But variety alone is not enough: tree age, the duration of the cold and the site of the grove also decide.
Building a high-density olive grove: five requirementsHigh-density planting is not a choice of variety but a five-component system — miss one and it performs worse than a traditional grove. Spacing, yields, the overlooked oil-content trade-off, and who it does not suit.
How to Grow an Olive TreeSoil, climate, watering, pruning and patience. A basic care guide for anyone planting an olive tree.
Why is my olive tree not bearing fruit? 9 causes and what to doBehind an olive tree that flowers but sets no fruit, fills one year and stays empty the next, or has never cropped at all, there is usually more than one cause. From the tree's age and lack of grafting to missing pollinators, insufficient chilling, drought and the wrong fertiliser or pruning, here is how to diagnose by symptom and what to do.
Can an olive tree be uprooted and moved?The technical answer is yes: olives can be moved at any age, with no upper limit. But "can be moved" and "is the same tree afterwards" are different questions. Winter timing, root-to-canopy balance, two to five years of care and three to five years without fruit are the real cost — and no large-scale Turkish study measures survival rates.
How to plant an olive saplingPlanting season, hole dimensions, removing a potted sapling, planting depth and the graft union, the basin and settling water — why settling water is given even in rain, first-year care and five common mistakes.
Where does an olive sapling come from? From cutting to laboratoryMost table olive varieties will not root, and those that do are clones of one another — defenceless against disease. Tissue culture reports up to 85% success in vitro, but zeatin is expensive.
When does the olive harvest begin?The harvest starts in late September and runs into February. Erkence is earliest, Memecik hangs into mid-December, and Mission's table and oil harvests are two months apart.
When to harvest olives: deciding with the maturity indexHarvest timing is set by the maturity index, not the calendar. The 0-7 colour scale, how to calculate it from 100 fruits, early versus late harvest compared, and ripening times by variety.
How are olives harvested? What five picking methods cost the tree and the oilHand picking, poles, combs, trunk shakers and straddle harvesters each charge a different bill — to the fruit, to the tree and to the acidity of the oil. Which method suits which grove, and what goes wrong on harvest day.
Grafting Olives: Changing Cultivar and Improving Wild TreesWhen grafting is needed, taking scion wood, bud and cleft methods, topworking and aftercare.
Olive Pruning: Why, When and HowWhy olives are pruned, when to do it, formative and production pruning, rejuvenation and high-density systems.
Fertilising Olives: From Soil Analysis to an Annual ProgrammeHow to read a soil test, which nutrients olives need and when, fertigation and organic matter management.
Irrigating Olives: When, How Much, HowOlive water requirements, critical periods, drip system layout, deficit irrigation and water quality.
Nutrient deficiencies in olive: from symptom to elementThe same yellowing can mean nitrogen, magnesium, zinc or iron, and the wrong element makes it worse. Standard leaf analysis values, symptom-to-element matching and the boron schedule.
Frost damage in olive trees: signs, risk factors and what to do after a frostThe generally accepted lower limit for olives is around -7 °C, but damage does not depend on the thermometer alone: how long the cold lasts, sudden drops, humidity, tree age and nutrition all matter. Here are the signs of frost damage on leaves, shoots, bark and fruit, ways to reduce the risk and which job to do when after a frost.
Pollination and pollinator varieties in olive98% of olive flowers drop. Whether the remaining 1-2% holds depends on having a pollinator in the grove. Gemlik is only partially self-fertile: in a single-variety grove harvest falls to a third.
What does crop insurance cover for olives, and what does it cost?Olives can be insured twice: for the crop and for the tree. Under TARSİM's 2026 tariff the hail package runs from 0.67% to 6.22% for oil olives and 1.44% to 13.52% for table olives, while frost cover sits on its own tariff and is optional. What a claim pays is set by the deductible and coinsurance: 60% frost damage on the standard option pays 35% of the sum insured.

Plant protection 12

Verticillium wilt: the disease that kills the tree and has no cureThe olive tree disease that kills: it survives over 10 years in the soil, blocks the vessels, and has no effective chemical control.
Weeds in the olive grove: bare soil is not the goalJohnson grass, Bermuda grass and fat hen. With perennials, ill-timed tillage spreads them while mowing stops the seed. Clean under the canopy, covered between rows.
Olive knot: galls, warts and a bacterium that enters through woundsThe bacterial canker among olive tree diseases that enters through wounds: galls and warts. Pole harvest and pruning errors spread it.
The olive moth: three generations, three kinds of damageThe olive pest with three generations: it winters in the leaf, eats the flowers, enters the fruit. One larva can take 30-40 buds.
Olive peacock spot: symptoms and a region-by-region spray calendarThe commonest of olive tree diseases: concentric rings on the leaf, shedding, a shrubby tree. Yield falls 20-25%; spray timing varies by region.
Olive black scale and sooty mould: the H on its backThe olive pest behind sooty mould: a scale with an H on its back. Losses of 60-70%; if parasitism tops 50%, do not spray.
The olive fruit fly: sting thresholds, traps and a control calendarThe olive pest that costs most: losses of 15-30% if left alone. Sting threshold 1% for table varieties, 3-4% for oil.
Olive anthracnose: the disease of the mummified fruit left on the branchUp to 50% crop loss in bad years. The source is last year's mummified fruit still on the branch, and the spray goes on before the autumn rains, not after.
Other olive pests: jasmine moth, psyllid and olive scaleThree olive pests overshadowed by the fruit fly: the jasmine moth on tender shoots, the cottony psyllid, and olive scale.
The olive pest calendar and intervention thresholdsMonth by month: which pest is at which stage, and when to count. Fly infestation thresholds, black scale shoot counts, and the three regional programmes for peacock spot.
Olive root rots: Armillaria and RoselliniaMistaking the yellowing for drought is the common error. Two soil-borne fungi kill the tree in its prime; there is no chemical cure — the work is water management and isolation.
Herbicide-free weed management in olive groves: from cover crops to autonomous robotsManaging weeds rather than eliminating them: cover crops, mulch, grazing, flame weeding and AI-assisted precision farming — five tools and a practical order for combining them.

Olive oil 53

How much olive oil comes from one kilo of olives?On the Turkish average, one kilo of olives gives around 170 grams of oil — about 185 millilitres. Put the other way round: a litre of oil needs 5 to 5.5 kilos of olives. Almost all the confusion in the calculation comes from treating kilos and litres as the same thing.
Akhisar Domat Olive Oil: stricter limits than its twinRegistered in 2017. Set against the Uslu oil registered the same day the difference is clear: peroxide ≤17 and acidity ≤0.65, both narrower.
Akhisar Uslu Olive Oil: oil from a black table cultivarRegistered in 2017. Uslu is principally a table cultivar; the certificate protects its oil separately. β-sitosterol sits in a very narrow 87.36-87.39% band.
Altınözü Olive Oil: one oil from four cultivarsRegistered in 2019. Halhalı, Saurani, Sarı Haşebi and Karamani are processed together. Alpha-tocopherol spans a wide 51.6-387.4 mg/kg.
Aydın Memecik Olive Oil: bitterness and pungency written into the definitionRegistered in 2020. Total phenols > 100 mg/kg, peroxide ≤ 18, defect median 0. Intense fruit aroma with pronounced bitterness and pungency.
The Ayvalık Olive Oil designation of origin: the chemical profile in the certificateRegistered in 2007. The certificate carries tables of fatty acids, sterols and phenolics — the ranges within which an oil counts as Ayvalık Olive Oil are set out in figures.
Bayramiç Olive Oil: aroma compounds defined as percentagesRegistered in 2022. The certificate defines aroma by compound rather than adjective: hexanal 36.15%, E-2-hexenal 26.14%. Iodine value 80-93.
Burhaniye Olive Oil: two thousand years attested by the Adramytteion excavationsRegistered in 2021. The certificate grounds two thousand years of olive growing in the excavation of an ancient city, and sets separate sensory thresholds for early and ripe harvest.
Ceyhan Olive Oil: harvest defined as “no green fruit left on the tree”Registered in 2022. The certificate defines harvest not by calendar but by the state of the tree: when no green fruit remains and oil content peaks.
Derik Halhalı Olive Oil: a burn reminiscent of red pepperRegistered in 2022. Low acidity (0.29-0.60%) and high phenols; the certificate describes the pungency directly — a lasting burn spreading over tongue and lips.
Edincik Su Olive Oil: ripening slowed by the seaRegistered in 2024. The certificate attributes aroma intensity to one cause: near the Erdek gulf the olives develop slowly and ripen late.
Edremit Olive Oil: thirteen separate fruity perceptions listedRegistered in 2017. The certificate lists thirteen fruity perceptions, from green almond to banana skin. At least one must be present at low or medium intensity.
Which olive oil is the best quality?The three measures that decide olive oil quality: grade, acidity and harvest year, plus how to read a label.
Erdek Kapıdağ Olive Oil: an oil whose grade changes in dry yearsRegistered in 2024. The certificate admits something rare: in dry periods the oil can fall from extra virgin to virgin grade.
How to make olive oil at home: crushing, kneading, separating and realistic expectationsPressing oil from a few kilos of olives at home is possible: the olives are crushed with their stones, the paste is kneaded, pressed and left until the oil separates from the water. But yield stays well below a mill's and quality is hard to protect. The steps, the equipment and the limits.
Geyikli Olive Oil: a registration that names its pollinatorsRegistered in 2020. From the Ayvalık cultivar; the certificate also records Gemlik and Hanım Parmağı as pollinators in the groves. Limits are set on 16 aroma compounds.
Güney Ege Olive Oils: a designation of origin across three provincesRegistration no 79, published in the Official Gazette in 2004, covers more than thirty-three districts across İzmir, Aydın and Muğla. The reasoning is not administrative but varietal: the region holds almost all of Türkiye's Memecik trees.
How soon must harvested olives be pressed? What waiting writes into the oilThe right answer is 24 hours, with 48 as the outer limit. Measurements on 228 batches across seven mills show that olives left waiting lose 42% of their polyphenols, more than half of their green aroma and a third of their oxidative stability — even while staying inside the legal acidity limit. In an 'on' year, with mill queues lengthening, this is the grower's most critical call.
Kilis Olive Oil: a cultivar reaching 33% oilRegistered in 2020. The Kilis Yağlık cultivar runs about 33% oil, far above the Turkish average. Small round fruit, thin skin, small stone.
North Aegean Olive Oils: a registration stricter than the food codexThe mark of ten localities rather than one district — and unusually, it sets tighter limits than the national standard on peroxide, FAEE, waxes and K270.
What is a malaxer? The tank where olive paste is kneaded, and the 27 °C limitA malaxer is the stainless steel kneading tank where crushed olive paste is slowly mixed so that oil droplets can merge. Time and temperature decide both yield and aroma, and this is also where the limit for "cold extraction" is drawn.
Milas Olive Oil: a press bed dated to 2000 BCRegistered in the European Union as well. The certificate's archaeological anchor is a press bed cut into rock at Pilavtepe — four thousand years old.
Mut Olive Oil: a landscape that needs no pesticideThe certificate's real claim rests on altitude and humidity: 10-40% relative humidity keeps out both the olive fly and peacock spot. That is why organic production is straightforward here.
Nizip Olive Oil: a registration that sets a floor for its raw materialRegistered in 2011. The certificate sets conditions on the fruit, not just the oil: 15-17 mm wide, 19-20 mm long, at least 25% oil. Fruit outside that cannot be used.
Osmaniye Olive Oil: a registration with sensory thresholds above sixRegistered in 2022. Fruitiness ≥6.4, bitterness ≥6.0, pungency ≥6.1 — unusually high thresholds. Milling within 48 hours of harvest is required.
What is riviera olive oil? How it differs from extra virgin, and what the label meansRiviera is not a grade of quality but the name of a blend: refined olive oil mixed with virgin olive oil fit for direct consumption. Under the Turkish Food Codex its free acidity may not exceed 1.0 and its peroxide value 15. What refining removes, what the label is obliged to say, and the real answer to the frying question.
Soma Olive Oil: how a cooler climate lifts yield in a lignite basinRegistered in 2023. Mean temperature 15.3 °C; the certificate ties that relative coolness to yields reaching 796 kg/da. Free acidity 0.18-0.55.
How Cold-Pressed Olive Oil Is MadeFrom tree to bottle: washing, crushing, malaxation and separation. Why the temperature must stay below 27°C.
Extra Virgin, Virgin, Riviera: Olive Oil Grades ExplainedWhat do 'extra virgin', 'riviera' and 'refined' mean on the label? The difference lies in the production method and acidity.
Tarsus Sarıulak Olive Oil: milling required immediately after harvestRegistered in 2020. The certificate ties product quality to one condition: the olives must be milled as soon as they are picked. Peroxide averages 8.23.
How to store freshly pressed olive oil: settling, sediment and the right containerOil fresh from the mill is cloudy and contains water and fruit particles. It is left to settle for a few weeks somewhere cool and dark in a container filled to the top, then the clear oil is separated from the sediment and moved into tins or dark glass. Oil left sitting on its sediment for months spoils.
Why is freshly pressed olive oil cloudy, and should you wait for it to settle?Oil straight from the mill is cloudy for a simple reason: droplets of water and fragments of fruit stay suspended in it. Cloudiness on its own is neither a mark of quality nor a defect. What matters is how long the sediment stays in contact with the oil, because that is where the actual defect is born.
Where does olive mill wastewater go? Lagoon rules and the two-phase optionWhen pressing starts, the dark liquid piling up behind the mill has one legal destination, and it is not the stream. Türkiye offers two lawful routes: switch to a two-phase system, or build a sealed evaporation lagoon. The lagoon's clay thickness, permeability, depth and area are all fixed by numbers in a ministry circular — worked example included.
What are zeytinyağlılar? The logic of Turkish dishes cooked in olive oilZeytinyağlılar are Turkish dishes in which vegetables or pulses are cooked with little water in plenty of olive oil until they absorb their own juices, then eaten cold at room temperature. They contain no meat, can be made a day ahead and taste better the next day. Vegetable dishes, stuffed leaves and vegetables, pilaki beans and Aegean wild greens are the four main families.
Olive OilThe difference between extra virgin, virgin, refined and riviera; what acidity means, how cold pressing works and how to store oil.
How to Read an Olive Oil LabelGrade, harvest year, acidity, origin and bottling place: which statements on a label are binding and which are just marketing — with a quick checklist.

How to Store Olive OilLight, heat, air and time — the four enemies of olive oil. Why the bottle next to your stove is in the worst possible place.
How to read an olive oil lab report: acidity, peroxide, K232, K270 and ΔKThe rows of figures on an olive oil lab report look cryptic at first. What do free acidity, peroxide value, K232, K270, ΔK, ethyl esters and sensory analysis measure, what are the limits for extra virgin and virgin grades, and how do you interpret a report using a worked example?
Does olive oil solidify in the fridge?Olive oil solidifies in the fridge, but this is not a purity test: sunflower and canola oil do the same. The rate depends on variety and fatty acid composition.
What to check when having your olives pressed at a mill: a grower's checklistThe same olives can give a very different oil when pressed at a different mill under different conditions. From what to do before bringing olives in to two-phase versus three-phase systems, kneading temperature, yield, milling fees and the questions to ask when collecting the oil, here is what a grower having olives pressed needs to know.
Why is olive oil bitter and pungent? Is it spoiled, or is it good?The bitterness and throat-catching pungency of freshly pressed olive oil is not a fault but a signal of polyphenols. Bitterness comes from oleuropein, pungency from oleocanthal, and both count as positive attributes in the international tasting standard. We also separate them from the defects they get confused with.
Tasting olive oil: defects and positive attributesLaboratory tests alone do not make an oil extra virgin — it must pass a tasting panel. The three positive attributes, the six defects in the standard, and what each one says about how the oil was made.
What Does Acidity Mean in Olive Oil?The 0.3% or 0.8% on the label has nothing to do with sour taste. Acidity tells you the condition of the fruit before pressing.
Olive Oil Fraud and Adulteration: How It Is Done and How It Is CaughtSeed oil blending, refined oil sold as extra virgin, soft deodorisation… The economics of fraud, the laboratory methods, and the home tests that do not work.
How is olive oil acidity measured? Titration, the formula and taking a sampleOlive oil acidity is measured in a laboratory by titration: the oil is dissolved in a solvent, free fatty acids are neutralised with potassium hydroxide, and the percentage is calculated as oleic acid from the amount used. The formula, a worked example, sampling and the limits of home test kits.
Does olive oil have a use-by date? Best-before dates, shelf life and oil past its dateOlive oil carries a best-before date, not a use-by date. Under the Turkish ministry's shelf-life guideline, oil past that date may be consumed, sold or donated if it was stored properly and its appearance, smell and taste are normal. Shelf life is set by the operator rather than by legislation — and even the format of the date reveals how long it is.
Ödemiş Çekişte Olive Oil: a separate harvest window called “çakır”Registered in 2020. The certificate names two harvest windows: early (green, November-December) and “çakır” (green turning pink, mid-December to mid-January).
What does "first pressing" olive oil actually mean?"First pressing" on its own is not a term defined in Turkish food law. Two expressions are defined — "first cold press" and "cold extraction" — and they describe different production methods. Using the text of the regulation itself, this piece explains the difference and what on the label is actually binding.
How to Tell Good Olive OilBitterness is a mark of quality, not a defect. Colour tells you nothing. The three attributes tasting panels look for, and a simple test at home.

Health and nutrition 25

What Is the Mediterranean Diet?Not a weight-loss plan but a pattern of eating. The basics of the Mediterranean way of eating, recognised by UNESCO, and where olive oil sits within it.
What does drinking olive oil on an empty stomach actually do?A spoonful of olive oil in the morning is a common habit, but there is no proven separate benefit to taking it on an empty stomach. What actually happens in the body, which claims have been measured and which are myth: the gallbladder, constipation, the calorie arithmetic and the truth about "liver flush" stones.
When can babies have olive oil?Complementary feeding starts at the end of the sixth month, and olive oil has a place at that table — because a substantial share of an infant's energy has to come from fat. EFSA's reference intake for 6-12 months is 40% of energy. But two separate questions get mixed up: adding oil to a purée is not the same as giving olive oil for constipation, and a table olive is not olive oil as far as a baby is concerned.
Which olive is healthiest?In olives the health difference comes from curing and salt, not the variety: nutrition, salt content and green vs black.
How Much Olive Oil a Day?Olive oil being healthy does not make it unlimited. A practical look at portions, calories and the logic of replacement.

Is Olive Oil Suitable for Frying?The most argued kitchen question. Smoke point is not the only measure; what really matters is how well the oil resists oxidation.
How many calories are in olive oil? Tablespoon, teaspoon and 100 mlOne tablespoon of olive oil has about 120 calories and one teaspoon about 40. Extra virgin, refined blends and sunflower oil carry almost the same energy. A measure table, plus how to count it in salads and cooked dishes.
Does olive oil raise cholesterol? Cholesterol content, LDL and the "clears arteries" claimOlive oil contains no cholesterol, and when it replaces saturated fat it helps maintain normal blood cholesterol levels. But every spoonful added to a diet also brings calories, and there is no evidence that olive oil clears arteries. A saturated fat table and the authorised health claims.
Olive oil or butter? What a 221,000-person study actually foundA Harvard-led study followed 221,054 people for over 30 years. Highest butter intake carried 15% higher mortality; highest plant-oil intake 16% lower. We look at what the numbers say — and what they do not.
Olive Oil and Heart HealthWhy is Mediterranean cooking so often linked with cardiovascular health? Unsaturated fats, polyphenols, and replacing saturated fat.
Olive oil and brain health: what a 92,000-person study and the randomised evidence sayThe headlines about olive oil and the brain are bold; the evidence is more measured. In a 92,383-person cohort followed for 28 years, more than 7 g a day was associated with a 28% lower risk of dementia-related death. The randomised PREDIMED trial points the same way.
The nutritional profile of olive oil: fatty acids, vitamins E and K, polyphenols100 grams of olive oil contain 73 grams of monounsaturated fat, 14 mg of vitamin E and 60 micrograms of vitamin K, with no protein, carbohydrate or cholesterol. A per-tablespoon table, and why polyphenols do not appear on the label.
What are the benefits of olive oil?Authorised claims, topics still under research and unproven claims kept apart — including the EFSA claim and PREDIMED.
Does olive oil have downsides? Calories, the gallbladder, old oil and fraudIn normal kitchen amounts olive oil is a safe food; its downsides mostly come not from the oil itself but from quantity, misuse and poor products. High calories, discomfort after fatty meals in people with gallstones, the habit of drinking it on an empty stomach as a "cure", repeatedly reused frying oil and adulterated products are the main risks.
Can people with diabetes eat olives and olive oil?It looks like one question but contains two: table olives and olive oil. Neither is off limits in type 2 diabetes; olives carry too little carbohydrate to measure a glycaemic index for, and oil carries none. The real limiting factor is not blood sugar but the salt in the brine.

"Jewels of the Adriatic": four countries choose to compete on quality, not volumeSlovenia, Croatia, Bosnia and Herzegovina and Montenegro together produce under 0.5% of the world's olive oil — yet Croatia finished second worldwide at the NYIOOC. A panel in Mostar proposed a shared umbrella brand: origin stays, common rules are the condition.
"Not definitive until November": Andalusian growers push back on the crop estimateAndalusia's agriculture ministry called its first crop estimate "high production"; cooperatives and COAG in Seville objected: recent heat will affect the crop and the estimate is not definitive until November. Türkiye is making its 2026-27 estimate in the field the same week — the same caution applies here.
3,200 trees and 72 varieties on 14 hectares of stone: the cooperative turning Dalmatian karst into grovesSome 100,000 hectares of karst lie neglected in Dalmatia while all of Croatia has 20,000–24,000 hectares under olives. In Desne a veterans' cooperative has grown 3,200 trees of 72 native varieties on 14 hectares of rock — a grove that doubles as a natural laboratory for climate resilience.
The 2026/27 season opens: first harvests in Ayvalık, Gemlik and BozcaadaThe new olive season opened with three events on 11-13 September. In Ayvalık, an on-year forecast of 400,000-450,000 tonnes of olive oil was voiced; in Gemlik the first olives were picked during the festival; and on Bozcaada the island's first olive oil was pressed with a portable system.
Turkey's 23 September fraud list: 21 olive oils, 11 from a single sellerTwenty-one olive oil entries joined Turkey's public food-fraud register on 23 September 2026 — two-thirds of what the other eleven announcements since April produced combined. In twenty of them the finding is identical: seed oil adulteration.
258 growers, €1.77 million: in Spain the fraud was not in the oil, it was in the paymentSpain's Guardia Civil has detained a table olive trader accused of defrauding 258 growers in Seville and Huelva of €1,765,220. The olives were real and the sales were real; the money never reached the producers. Investigators seized 1,220,650 kilos of Manzanilla olives.
A 282-member doctors' cooperative puts sensors in the olive groveA cooperative founded by doctors in Adana is monitoring water and fertiliser with buried sensors across 100 of its 135 dönüm of bearing olive grove, funded with 2 million lira.
The EU's newest olive oil registration is in northern Italy: Olio dei Colli di Bologna gets PGI statusThe European Commission has entered olive oil from the hills of Bologna into the Union register of geographical indications. The specification caps free acidity at 0.3 percent, well under a third of the legal limit for extra virgin, and writes five local Bolognese cultivars into the definition.
The 12.5% US tariff: the competitor is exempt, the Turkish exporter is notMustafa Kürlek notes the 12.5% additional US tariff on Turkish olive products is not applied to competitors such as Tunisia, and calls for DFİF and Eximbank measures.
Opening prices in Akhisar: 60 lira for double Domat, 10 lira for milling olivesThe season's first purchase prices for Domat olives have formed in Akhisar: 15 to 60 lira a kilo by size, and 10 lira for fruit sold for milling. The local chamber of agriculture says prices are below last year's and has called for a joint table. Farm input costs rose 27.6% over the same period.
Concordat in Akhisar: a one-year moratorium for Baktat ZeytinA Turkish commercial court has granted a one-year definitive moratorium to Baktat Zeytin, a table-olive processor in Akhisar. We set out what the ruling means and why it matters for the sector.
Recall in Germany: MOSH/MOAH in pomace oil — not olive oilGermany's official food safety portal has recalled a 4-litre pomace oil sold in Turkish shops. The product is not olive oil but olive pomace oil; we explain the difference and what MOSH/MOAH are.
A 2,000-year-old olive grove endowment in Antalya: 600 trees, “never to be cut or sold”The excavation results from Lyrboton Kome in Antalya have been presented. Inscriptions record a family endowing its farm and 600 olive trees in perpetuity, with an explicit clause: these trees can never be cut, sold or put to another use.
Antalya's crop is up 30%: of 70,000 tonnes of olives, 55,000-60,000 head for the millAccording to the Antalya Commodity Exchange, the province's olive crop is rising about 30% from some 55,000 tonnes last season to around 70,000 tonnes, with 13,000-14,000 tonnes of olive oil and 10,000-15,000 tonnes of brined fruit expected. Harvest opened on 15 September. There is movement on the registration front too: an EU application has been filed for the Tavşan Yüreği olive, and a geographical indication file is under way for the Beylik variety.
Five adulteration raids in 15 days in Aydın: 4,063 litres of oil, 7,922 empty tinsPolice in Aydın say five operations between 1 and 15 September 2026 seized 4,063 litres of unlabelled adulterated oil and 7,922 empty tins. The goods were valued at about 2.72 million lira and the administrative fines totalled 1.85 million lira. The number of empty tins was nearly double the litres of oil seized.
Olive fruit fly warning before harvest in Aydın: check groves, spray only above the thresholdThe Didim District Directorate of Agriculture and Forestry, together with the Aydın Provincial Directorate, has warned growers about the olive fruit fly ahead of the harvest. Growers were asked to check groves regularly, monitor pest density and, if needed, act only with products licensed for olives and at the right time. Fly pressure rising in autumn cuts both yield and oil quality.
Table olive tasting panel training in AydınAydın Commodity Exchange is extending its sensory analysis experience from olive oil to table olives, with 20 panellists trained over three days.
The UN names 2026 the Year of the Woman Farmer: in olives the labour is women's, the records are notFAO reports that agrifood systems employ 36% of working women and 38% of working men; closing the gender gap would add 1% to global GDP (about $1 trillion) and improve food access for 45 million people. In olives, most harvest labour is women's — title deeds and decisions are not.
Twenty-one olive oils on the ministry's adulteration list in one day, eleven from a single Antakya businessOf the 40 records added to Turkey's counterfeit-and-adulteration list on 23 September 2026, 21 are olive oil, and 20 of those were found to contain seed oil. Eleven records belong to a single business registered in Antakya, marketing under Aegean origin names such as Ayvalık, Akçay-Altınoluk and Kazdağları. Sixteen of the containers were five litres.
Algeria expects a record 150,000 tonnes: the Mediterranean supply map is shiftingAlgeria's 2025/26 olive oil output is expected to exceed 150,000 tonnes — up 76% on the previous season and a third consecutive rise. With domestic consumption near 81,000 tonnes, an exportable surplus appears. In a season when Turkish exports fell 62% by value, that means new competition in the bulk market.
17th Advanced Course in Olive Growing opens in Córdoba as the IOC and IFAPA move towards genetic resources cooperationAndalusia's Institute of Agricultural and Fisheries Research and Training (IFAPA) opened its 17th Advanced Specialisation Course in Olive Growing in Córdoba on 14 September, with the International Olive Council giving the opening lecture. The Council has approved signing a memorandum of understanding with IFAPA, which hosts one of the world's key olive germplasm collections.
Black olive harvest paused for ten days in Akköy, Didim: a price ladder from 30 to 100 liraIn Akköy, a village in the Didim district of Aydın, growers and olive buyers have jointly agreed to suspend black olive harvesting and buying for ten days, saying announced prices do not cover costs. The price ladder published by the village headman's office runs from 100 lira a kilo for the largest grade down to 30 lira for the smallest. Growers say picking costs alone exceed the price on the lower grades.
The world's largest bottler is for sale: a €500 million race for DeoleoDeoleo, owner of Bertolli and Carbonell, holds 22% of global bottled olive oil sales. Italy's Coricelli leads at €500 million, Spain's Dcoop cooperative at €470 million. The Spanish government regards the company as nationally strategic. Because Deoleo is a major bulk buyer, the outcome matters to Turkish exporters too.
Edremit Chamber: olive oil needs at least 50 lira per litre in supportChamber President Ahmet Çetin says the wholesale price has fallen to 200 lira, below the cost of picking. The level needed to cover costs is 300 lira. Harvest is expected 15-20 days early.
Andalusia moves against North African imports: 76% of what arrives is extra virginAndalusia's farm sector objects that more than 76% of the olive oil imported into the region in early 2026 was extra virgin. The regional minister has requested exceptional measures under Article 195 of the EU regulation. Türkiye could meet the same door.
Andalusia finally puts a number on it: 1.26 million tonnes of olive oil, up 24%Andalusia's agriculture ministry published its 2026/27 aforo on 29 September in Mengíbar: 1,261,200 tonnes of olive oil, 23.9% above last season and 44% above the five-year average. The heat warning growers raised in early September made it into the forecast's own reasoning. Four times Turkey's entire season output is entering an already soft price environment.
Andalusia bans night harvesting again for 2026/27: 8,127 birds counted on 137 hectaresAndalusia has again suspended night-time mechanical harvesting in super-intensive hedgerow olive groves for the 2026/27 season. The resolution is dated 30 July 2026, was published in the regional official gazette on 5 August and is valid for one year. The justification is field counting: 8,127 birds from 66 species on 137 hectares. The suspension was first introduced in 2019 and has been renewed every season since.
Palestinian olive oil: output down from 33,000 to 7,000 tonnes — the cause is access, not the cropIn a productive season Palestine yields 33,000 tonnes of olive oil; last season it produced 7,000. Seventy per cent of the groves sit in the northern West Bank, reached through 62 agricultural gates, and shipping times have gone from ten days to two months.
Gaza's olive report: 150,000 trees left of two million, production down 87.5%According to a report from Gaza's Ministry of Agriculture, olive groves have shrunk from 50,000 dunums to 5,000 and the olive crop from 40,000 tonnes to 5,000. The loss is not confined to the grove: milling capacity has fallen from 150 tonnes an hour to 25, and the number of growers from 20,000 to 1,000.
Two pressures before the harvest: costs and 100,000 tonnes carried overThe chamber of agriculture wants 50 lira per kilo; daily labour has passed 1,500 lira. Exporters report 100,000-120,000 tonnes carried over from previous seasons.
5,300 litres of adulterated oil in one van at Köşk — more than all of SeptemberA van stopped on the Aydın-Denizli highway was found to be carrying 5,300 litres of counterfeit and adulterated olive oil, valued at 1.6 million lira; two people face proceedings. The single shipment exceeds the 4,063 litres seized across five operations in the province in the first half of September.
Green olive harvest begins in Málaga: 2.5 to 3 million kilos expected for AloreñaTable olive harvesting has begun in Spain's Málaga province with better prospects after years of drought. The protected-origin Aloreña de Málaga is expected to yield 2.5 to 3 million kilos, and trees are heavily laden with Hojiblanca, which supplies more than 90 per cent of the province's table olives. September heat, however, is shrivelling fruit on rain-fed land.
Manisa's olive trees reach 38 million: 8 million added in three years, sector asks for premium supportManisa's olive tree count rose from 30 million in 2023 to 38 million in 2026. Data shared at a sector meeting hosted by the Manisa Commodity Exchange shows the province alone accounts for 17 percent of Turkey's oil-olive output and 22 percent of its table-olive output. The meeting also reported that annual per-capita olive oil consumption in Turkey has climbed from 1-1.5 kg to 2-2.5 kg. Exchange chairman Sadık Özkasap called for higher state support and premium incentives against the lower processing costs of Spain, Tunisia and Morocco.
Marmarabirlik opens crop declarations on 21 September: no declaration, no purchaseCrop declarations for the 2026-27 business year open on 21 September and close on 23 October at cooperatives affiliated with Marmarabirlik, Türkiye's largest table olive cooperative union. Members who do not file cannot sell to the cooperative, and the declared figure is a binding commitment covering oil olives too. In Orhangazi some 300 members are close to expulsion under the union's fifty-percent delivery rule.
EIA approval for a 200 t/day olive oil plant in MudanyaA 9.5 million lira olive oil plant planned in Mudanya, Bursa, has received a positive environmental impact decision: 200 tonnes of olives a day, around 100 operating days a season.
Harvest opens in Mut: 300,000 tonnes expected, orchard prices start at 10 liraMut's district agriculture directorate reports 300,000 tonnes expected from 269,000 decares, with orchard prices ranging from 10 to 60 lira by sieve size. Yield is high but growers are unhappy with prices. Set against our own Mersin figures the tonnage leaves an unresolved measurement gap, and we report it as such.
Orhangazi olive oil starts on the road to geographical indication, with samples to be tested for acidity and polyphenolsThe Orhangazi Chamber of Commerce and Industry has begun preparing a geographical indication application for "Orhangazi Olive Oil". More than 20 producers will be consulted, samples tested in Bursa and the influence of the Lake İznik basin studied. The area's Gemlik Olive registration covers only table olives.
Orhangazi's crop is doubling: the oil olive share climbs from 10% to 40%According to figures from the Orhangazi District Directorate of Agriculture and Forestry, last season's crop of roughly 35,000 tonnes could double this year. But in Türkiye's table olive heartland the real shift is in the split: the share pressed for oil is expected to rise from 10% to 40%. Mills are already in maintenance, and the grower's income now depends on fruit size.
Osmaniye expects 107,000 tonnes: 3.5 times last season, in line with on-year averagesThe governor's office in Osmaniye says the province's roughly 10 million olive trees are expected to yield more than 107,000 tonnes this year. That is 3.5 times last season — but 2025-2026 was an off year, and the forecast is consistent with on-year yields. Small discrepancies remain in tree counts and ranking.
Pakistan to plant 2 million olive trees in three years to cut edible oil importsPakistan's Ministry of National Food Security and Research plans to establish olive groves on 15,000 acres (about 6,070 hectares) over three years and supply 2 million plants in that period. The country imports roughly 90 per cent of its edible oil; the import bill reached 4.97 billion dollars in 2024-25.
Portugal heads back to 177,000 tonnes: output up 10%, farm diesel up 60%Portugal's olive association Olivum expects production to rise by about 10% in 2026/27 — a return from 160,000 tonnes to the 177,000 of two years ago. The same statement records a 60% rise in the price of agricultural diesel.
The crop is heading for 500,000 tonnes, exports fell to 17,000: the sector wants a premium and an exchange-rate mechanismIndustrialists and exporters meeting in Izmir put this season's olive oil crop at 500,000-600,000 tonnes. Last season Türkiye shipped 17,721 tonnes of olive oil: down 62% in volume and 59% in value. The crop is not the problem; selling the crop is.
Crop forecast climbs as the minimum-price debate returns: what the exchange numbers sayWith the 2026 harvest approaching, crop forecasts are up 40 percent in some provinces and growers want a floor price. Our exchange series shows why the dispute is really about olives, not oil.
The official olive figure is measured in the grove: Türkiye's 2026 crop survey is under wayTürkiye's official olive crop figure is not produced at a desk. It comes from agricultural engineers counting fruit load tree by tree. A provincial crop estimation commission met in Denizli this week while field inspections continue in the districts. The national figure is assembled by an official delegation coordinated by the National Olive and Olive Oil Council across 41 provinces, and last season it was announced on 24 October.
Syria's crop doubles to 954,000 tonnes — and the oil still only feeds itselfSyria's Ministry of Agriculture expects 954,000 tonnes of olives in 2026, up from 412,000 last season. The 101,000 tonnes of oil that implies barely covers domestic consumption — a doubled crop that still produces no export surplus.
In Söke, one day's wage costs ten kilos of olive oilOver 1,000 tonnes of table olives are expected in Söke's Ağaçlı. Two figures given by the headman sum up the season: oil at 160 lira wholesale, a day's wage at 1,600.
Co-op branding in the adulteration list: one name, four separate announcementsAll eight olive oil entries in Turkey's 30 September 2026 food-fraud announcement come from a single province, Aydın, and all eight carry the same finding: seed oil blended into oil sold as extra virgin. The brand names tell a second story — three of them invoke a cooperative or a producers' union. Read as a time series, the live list shows one trader's name across four separate announcements, under a new brand each time.
Adulterated olive oil costs more than the real thing: price is no longer a sign of authenticityDiker, president of the Edremit Chamber of Agriculture, says adulterated oils sold online now exceed the wholesale price of genuine oil: wholesale starts at 240 lira, the fake sells above 300. Our exchange data complicates the picture — genuine extra virgin in Aydın is already 307.60 lira.
Tunisia sold 381,000 tonnes of olive oil in ten months: 85.5% in bulk, half of it to Spain and ItalyAccording to the National Observatory of Agriculture (ONAGRI), Tunisia exported 381,200 tonnes of olive oil in the first ten months of the 2025/26 season — volumes up 50.8% and receipts up 41.2% year on year. But 85.5% of it left the country in bulk, and more than half went to Spain and Italy. Packaged oil averaged 16.7 dinars per kilo against 11.8 for bulk. Production is set to fall 40% next season, which changes the bulk market Turkish exporters face.
Tunisia exported 368,000 tonnes of olive oil — but earned less per tonneTunisia's agriculture observatory ONAGRI reports olive oil exports up 55.3% by volume and 44.4% by value in the first nine months of 2025/26. The gap between the two means about 7% less earned per tonne.
Tunisia's output falls from 500,000 to 300,000 tonnes — revenue may holdTunisia's National Chamber of Olive Producers expects olive oil output to fall from 500,000 to 300,000 tonnes in 2026/27, citing alternate bearing. Revenue is still expected to match last season because prices are higher. Türkiye's most direct bulk competitor is shrinking.
Table olives with half the salt: potassium, calcium and magnesium instead of sodiumResearchers at Spain's Instituto de la Grasa (CSIC) cut sodium in pimento-stuffed green Manzanilla olives from 14,216 mg to about 7,100 mg per kilogram. Potassium, calcium and magnesium salts added to the packing brine made the olives a source of these minerals.
The International Olive Council grows: Iraq joins, Brazil and South Africa applyThe International Olive Council (IOC) saw three developments in a month: Iraq became a full member on 8 August, South Africa submitted its membership request on 8 September and Brazil on 9 September. The expansion reflects olive oil's shift towards production and consumption areas beyond the Mediterranean.
Xylella has left Puglia: seven olive trees test positive in CalabriaThe pauca subspecies of Xylella fastidiosa, which dries out olive trees, had been confined to Puglia since 2013. In Taurianova, Calabria, 7 of 35 samples tested positive; the region issued a quarantine decree on 1 September with a 2.5 km buffer zone.
Greece finally puts a number on its cost: €3-3.5 a kilo, up to €5 with labourFor the first time Greece has put a per-kilo figure on its olive oil production cost: €3.00-3.50, rising to €4.00-5.00 once labour is fully counted. The producer price stands at €3.90-4.20, at or below that cost. Spain's €1.70-2.00 for the same item shows where the competitive gap actually sits. Greek output for 2026/27 is estimated at 280,000-330,000 tonnes.
Greece heads for 300,000 tons: first lot sold at €5.95 after last year's €7.85Greece expects its largest olive oil harvest since 2022/23 in 2026/27, with industry estimates near 300,000 tons. The season's first lot — 55 tons of extra virgin in Laconia — changed hands at €5.95 per kilo, down from €7.85 a year earlier. Carryover oil sells near €3.40 and new-crop producer prices are expected around €4. A simultaneous rebound across the three largest producers pushes down the world price Turkish exporters will meet.
Greece opens the season at €4: no scarcity in the Mediterranean, but pressure on priceManolis Giannoulis, president of the National Interprofessional Olive Oil Organization, expects the season to open at around €4 per kilogram. Mediterranean output is forecast at 3–3.2 million tonnes: no record, but enough to meet demand. The market is quiet, buyers are few, and costs plus North African imports keep the pressure on.
Skilled operators for olive mills: training ends in Milas, Muğla trains women operatorsAhead of the harvest, two training programmes in Muğla focus on operators, the most critical link in olive mills. A three-day operator course run by MİTSO, Milas Tariş and HAUS Makine has ended in Milas, and the Muğla Chamber of Commerce and Industry is launching a 50-place "Women's Hands in Industry" programme to train women as mill operators.
Olive oil exports still down 62% at the end of August: bulk loses 73%According to the Aegean Olive and Olive Oil Exporters' Association, olive oil exports between 1 November 2025 and 31 August 2026 fell 62% in volume and 59% in value. Bulk sales lost 73%, the US market 70%. Table olives, by contrast, held their ground.
Olive oil exports down 62% by value as a record harvest is expectedOlive and olive oil exports fell 34% to $260 million between 1 November 2025 and 31 May 2026. Table olives held at $172.5 million while olive oil dropped to $69 million. The target is a return to $1 billion.
Six jailed for taking produce without paying: the grower's most fragile moment is the start of harvestIn Bozdoğan, Aydın, six people who bought olive oil, nuts and livestock from growers and failed to pay were caught in a simultaneous operation across three provinces on 15 September and jailed on 17 September. The method is a familiar one: the first purchase is paid in full, and once trust is established the large purchase is not. In the week harvest begins, growers have three concrete protections.
Olive oil got cheaper in the UK and Filippo Berio lifted its share to 15%The 2025 accounts of Filippo Berio's UK company show how falling prices reached the shelf: volumes up 37%, revenue up 16%, market share from 10.7% to 15.1%. The category grew 6% and lower wholesale costs were passed on to shoppers.
Spain steps back from vetoing Deoleo's sale: the door opens for Italy's CoricelliMadrid's position on the sale of the world's largest olive oil bottler has shifted: in early September a Spanish buyer was preferred, and on 18 September Italy's Coricelli was reported to be seen as the best-positioned candidate. The government's lever is a foreign investment screening regime that covers EU investors too and runs to 31 December 2026. Because Deoleo is a major bulk buyer, the outcome matters to Turkish exporters.
Spain decides in November: will part of a 1.6 million tonne crop be withdrawn from the market?Spain's first national aforo for 2026/27 was presented in Jaén on 1 October: 1,602,596 tonnes of olive oil, 23% above last harvest. With carry-over stock, total availability approaches two million tonnes, and the Ministry of Agriculture will decide in the first half of November whether to activate a temporary withdrawal mechanism that has never been used. The ceiling on the world price Turkish exporters will face is being set here.
In Spain the cost sits above the price: €5.31 in a traditional grove, €3.46 at the gateOlive cultivation costs have risen 57% in six years and reach €5.31 per kilogram in the most traditional groves, according to an AEMO study. The same week, Spain's producer price was €3.46. The Andalusian cooperative federation, with 342,000 members, is asking not for aid but for a change to the Food Chain Law.
Spain's competition authority opposes the withdrawal rule: "very negative for competition and consumers"On 5 October the CNMC published its report on the draft rule that would withdraw part of Spain's olive oil from the market in the event of oversupply in 2026/27.

Yet even as output recovers, the state is pumping liquidity into mills: the 40-million-euro "Cambiale Frantoi Oleari" offers zero-interest loans of 3,500 to 50,000 euros. The five-year national olive plan aims to lift production by 25%.
