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.
