Ceyhan Olive Oil: harvest defined as “no green fruit left on the tree”

Most certificates give harvest timing in months. Ceyhan Olive Oil's leaves the criterion to the tree itself.

The record

That the registrant is a municipality is notable — most olive registrations are held by chambers of commerce, commodity exchanges or district governorships.

The harvest criterion

According to the certificate, olives destined for oil are harvested in the months when no green fruit remains on the tree and the oil content of the fruit has reached its maximum.

This is a definition tied to ripeness rather than the calendar — a sounder criterion, since the climate varies from year to year. The certificate acknowledges as much by saying “depending on climatic conditions”.

Oil content rises as the olive approaches black maturity, peaking at full ripeness. We covered that curve in the life cycle of an olive tree.

Cold pressing

Once milled to paste, the oil is extracted below 27 °C by appropriate technique — extra virgin olive oil under the Turkish Food Codex.

The same threshold appears in the Ödemiş Çekişte Olive Oil certificate; 27 °C is the internationally accepted limit for cold pressing.

The eastern Mediterranean

Ceyhan is one of Adana's olive production centres. Osmaniye Olive Oil (1317) and the Hatay registrations lie in the same belt — the eastern Mediterranean forms its own line on Türkiye's olive map.

The criteria the document binds

The registration does not only protect a name; it defines the product numerically:

The free acidity limit of 0.8% is the codex ceiling for extra virgin olive oil. Here the registration restates the codex; what distinguishes the product is the other criteria below. Capping processing at 27 °C is what cold extraction means in practice: above that threshold yield rises but aroma compounds and phenolics are lost.

Inspection. The inspection body convenes with at least 3 kişi, at least once a year. Results are reported under Industrial Property Law no. 6769 and submitted to the Turkish Patent and Trademark Office.

The production steps in the document

The registration describes production step by step. The document's own sequence:

1. Üretim Metodu — Ceyhan Zeytinyağı üretim aşamaları aşağıda verilmiştir.

2. Zeytinlerin Hasadı — Ceyhan Zeytinyağının üretiminde kullanılacak zeytinler coğrafi sınırdaki hasat dönemi içerisinde zeytin meyvelerine hasar vermeyecek şekilde makine ve/veya el ile özenle zeytin ağaçlarından toplanır.

3. Zeytinlerin Muhafazası — Hasat edilen zeytinler gıda ile temasa uygun olan temiz, tercihen plastik kasalarda hava alacak şekilde taşınır.

4. Zeytinlerin Temizlenmesi ve Yıkanması — Zeytinlerin hasat edilmesi sırasında bulunabilecek dal parçaları, toz, toprak, yaprak vb.

5. Zeytinlerin Kırılması ve Ezilmesi — Ezme işlemini kolaylaştırmak için zeytinler parçalarına ayrılması ile yağ veriminin artırılması sağlanır.

6. Zeytin Hamurundan Yağın Ekstraksiyonu — Ekstraksiyon işlemleri; presleme (geleneksel yöntem), santrifüjleme (modern yöntem), seçici filtrasyon (perkolasyon/sinolea yöntemi) gibi yöntemlerden biri ya da birkaçı kullanılarak gerçekleştirilir.

7. Zeytinyağından Karasuyun Ayrılması — Bu aşamada su, yağ ve zeytin posanın tamamen birbirinden ayrılması sağlanır.

8. Zeytinyağının Depolanması ve Ambalajlanması — Üretilen zeytinyağı tüketime hemen arz edilmeyecek ise gıda ile temasa uygun örneğin; paslanmaz çelik tanklarda, doğrudan ışık almayacak şekilde serin ortamlarda, nem ve kokudan ari depolama koşullarında muhafaza edilir.

That this sequence is binding is what separates a geographical indication from a trade mark: a mark says who produced something, a geographical indication also sets down how it must be produced.

Its place in Adana's olive production

86% of the province's fruit goes to oil. An oil-based registration matches how the province actually produces.
