Key Differences Between Kalamata Olives and Black Olives

Origin

Kalamata olives belong to the black olive family, however they are actually dark brown in color and large in size.  It originated from the city of Kalamata, which is in the region of southern Peloponnese, Greece. Today they can be found growing in parts of the world that include the U.S. and Australia.

Black olives, however, have many varieties and can be found growing all over the world, including Greece and the Mediterranean.

Harvesting Process

Kalamata olives have to be handpicked in order to avoid bruising, and cannot be harvested green. While there are some commercially grown black olives that are hand-picked, they are typically picked using machinery that shakes the olives from the branches.

Curing Method

Harvested when they are fully mature, Kalamata olives then cured in plain or salty water. The curing process takes about a week to remove their bitterness. When ready, kalamatas are then placed in jars that contain a brine made out of vinegar and sometimes olive oil and lemon wedges for flavor.

Black olives, in comparison, can be harvested green and can be artificially ripened using a brining method. To enhance the flavor, an alkaline solution called lye is used and iron is used to lock in the color.  The final step is to add carbon dioxide in the cans and then seal and steam them. 

Appearance

Kalamatas are said to have a deeper purple color that almost looks brown. They are oblong shape that is almost almond-like. They are typically twice the size of black olives.

Black olives have a more round shape, are squatter and have more of that traditional olive shape that you’re familiar with.

Taste

Kalamata olives have a richer taste that can be almost sweet and fruity. In contrast, black olives have a more mild taste with less robust flavors.

Keep in mind that both Kalamata and black olives can be bitter when they are first harvested. It’s when they are cured, that they become more appetizing, revealing their flavor characteristics.
