Köstem Zeytinyağı Çiftliği (Köstem Olive Oil Farm & Museum)

Agricultural scientist Levent Köstem built this working olive farm on the Urla peninsula around groves that supply its own early-harvest, cold-pressed oil, and added a museum tracing Aegean olive cultivation on the same grounds. Visitors taste single-estate oils pressed from the surrounding trees rather than blended cooperative stock.
