The Kalamata olive is a large, Purple olive with a smooth, meaty texture named after the city of Kalamata in the southern Peloponnese, Greece.[2] Often used as a table olive, they are usually preserved in wine vinegar or olive oil. Kalamata olives in the European Union (EU) has PDO status; whereby only olives originating from the Kalamata region have the sole rights to be branded as Kalamata if sold in the EU.[3]


Kalamata olives are grown in Kalamata in Messenia and also in nearby Laconia. They are an almond-shaped, plump, dark purple olive,[4] from a tree distinguished from the common olive by the size of its leaves, which grow to twice the size of other olive varieties.[2] The trees are intolerant of cold and are susceptible to Verticillium wilt but are resistant to olive knot and to the Olive fruit fly.[5]

Kalamata olives cannot be harvested green and must be hand-picked in order to avoid bruising


There are two methods of preparing Kalamata olives, known as the long and short methods. The short method debitters the olive by packing them in water or weak brine for around a week. Once complete, they are then packed in brine and wine vinegar with a layer of olive oil and slices of lemon on top. The olives can be slit in order to decrease the processing time. The long method involves slitting the olives and placing them in salted water in order to debitter them, a process that can take as long as three months. Levels of polyphenol remain in the olives after processing, giving them their slightly bitter taste.[6]
