Akhisar Uslu Olive: the measured specification of a black table olive

Uslu is one of the cultivars most often named in Turkish black table olive production, yet its measured values are scattered. The registration certificate gathers them in one place — and corrects a published error.

The record

Because it is a designation of origin, every stage must take place inside that boundary. We set out the distinction on the list of registrations.

The measured fruit

One correction: a widely used source gives Uslu's flesh ratio as 15% and its stone ratio as 85%. That is physically impossible — the two values have been transposed. The certificate gives the correct figure: flesh 85.17%. The value on our Uslu olive page comes from here.

Tree and fruit

Under irrigation the tree grows very vigorously, forming a large, broad crown with dense branching and heavy foliage. Planting distances are therefore wide: 6×8 m or 7×7 m.

The fruit is medium-sized and oval. It is asymmetric lengthwise — the tip curves slightly downward — and symmetric across. The tip is rounded, without a nipple. Bright green when unripe, glossy deep black when mature; the ripe flesh is cream-coloured and soft, and separates easily from the stone.

Product classes and calibre

The certificate defines calibre separately for each product form — the same cultivar goes to different sizes under different processing:

⚠ The certificate limits the tolerance on fruits per kilogram to (−3).

The two brines

Fermentation brine — to remove bitterness: prepared with drinking water at 0.5-7% salt and 0.065-1.2% acid, in accordance with the Table Olive Codex.

Packing brine — for presentation: drinking water with table salt and, where required, lactic acid, spices, vinegar, olive oil and herbs such as bay leaf.

We covered these processes generally in types of table olive.

Growing

The certificate describes planting step by step: pits of 80×80 cm, topsoil and subsoil kept separate, planting between November and April, shifted to March-April if the winter runs cold. Soil analysis before planting is mandatory.

And one provision governs table quality directly: harvest is by hand, and the olives are collected into crates. Bruised and damaged fruit in table olives is the consequence of pole-beating and sacks.

In short

The name Akhisar Uslu Olive belongs to Uslu-cultivar olives grown in Akhisar and five neighbouring districts, harvested by hand, and meeting nine measured values. What the certificate adds is a single reliable place for figures that were scattered — and, in one source, reversed.
