Akhisar Domat Olive: the specification behind stuffed olives
Registered in 2010. The certificate sets calibre separately for each product form — 170-290 for stuffed, 110-260 for cocktail. One cultivar, different sizes.

Domat is the backbone of Turkish green table olive production. What makes its certificate interesting is that it does not give a single calibre — it defines separate size bands according to which product the fruit will become.

Calibre by product
This table is the certificate's distinctive part — each product form demands its own size band:
| Product | Fruits/kg bands |
|---|---|
| Stuffed olives | 170-200 · 201-230 · 231-260 · 261-290 |
| Sliced green · cracked scored | 160-190 · 191-220 · 221-250 · 251-280 |
| Cocktail · pitted · natural pink · pepper/almond stuffed | 110-130 · 131-150 · 151-170 · 171-190 · 191-220 · 221-240 · 241-260 |
The logic is simple: a fruit that will be cored for stuffing must fall within a particular size, whereas cocktail olives can use a far wider range. The cultivar's large fruit provides that latitude.
Fruit form
The fruit is large and cylindrical, symmetric both lengthwise and across, with its widest point at the middle. It carries a distinguishing mark: a pronounced ridge running on opposite sides from stalk to tip. The tip is flat or rounded, and the stalk cavity usually round — sometimes shuttle-shaped — and of medium depth.
Ripe flesh is of medium firmness, with a medium-strength bond to the stone — exactly what green table processing wants: firm enough to survive stuffing and slicing, soft enough not to eat tough.
The tree grows vigorously, generally forming a large, broad, spreading crown with dense branching.
In short
The name Akhisar Domat Olive belongs to Domat-cultivar olives grown in Akhisar and five neighbouring districts. What the certificate adds is eight measured values and a calibre table that splits by product form — the size of the fruit decides whether it becomes a stuffed olive or a cocktail one.
