Edremit Gulf Green Scored Olive: a registration that defines altitude and slope
Registered in 2014. The certificate draws the boundary topographically as well as administratively: 50-250 m altitude, 5-6% slope. Debittering is entirely natural.
Boundaries in geographical indications are usually drawn with district names. This registration goes a step further: it also states at what altitude and on what slope the olives must grow.
The record
| Registration no | 189 |
| Official notice | 31.12.2014 · Official Gazette 29222 |
| Type | Designation of origin |
| Registered by | Edremit Chamber of Commerce |
| Area | The Gulf of Edremit · altitude 50-250 m · slope 5-6% |
| Cultivar | Ayvalık (Edremit) |
Writing altitude and slope into the definition narrows which groves can qualify.
Natural debittering
The certificate's second distinguishing provision concerns processing: the product is made using entirely natural debittering agents, by a preparation and processing method of its own.
The common way to remove bitterness from green table olives is caustic. The “scored” method splits the fruit and washes the bitterness out with water — slower, and without chemicals. We compared the methods in types of table olive.
Stone measurements
The certificate measures the stone in detail:
| Criterion | Value |
|---|---|
| Weight of 100 stones | 43.77 – 63.77 g |
| Volume of 100 stones | 43 – 63 cm³ |
| Stone length | 11.76 – 13.76 mm |
| Stone width | 6.15 – 8.15 mm |
| Stone length/width | 1.68 – 1.88 |
| Stone share of fruit | 14.00 – 15.48% |
A stone share of 14-15.48% means a flesh ratio of 84.5-86% — the band a green table olive wants.
Tree and pollination
Under good husbandry the tree grows vigorously and forms a large tree; branching is sparse and foliage light. Branches are narrow-angled and grow upright — the certificate notes this makes the tree suited to mechanical harvesting.
Flowering falls between 16 May and 9 June. The cultivar is self-fertile, though Gemlik, Memecik and Erkence may serve as pollinators. Alternate bearing is moderate.
In short
Edremit Gulf Green Scored Olive is a green table olive whose boundary is narrowed by altitude and slope, and whose bitterness is removed naturally. It is one of four registrations built on the Ayvalık cultivar — the others being Ayvalık Olive Oil, North Aegean and Burhaniye.
