What Are Black Olives?

Black olives are usually soaked and kept in a solution of sodium hydroxide. While in the need for use they are washed very well in water so that the entire content of oleuropein is removed. They are generally milder in taste then green olives. This is because they are not usually fermented before they packed. They are harvested when completely ripe. They are not treated with alkali but are at a standstill pickled in salt water.

The common black olive, is also known as Mission olive is a ripe green olive. It obtains its typical colour and taste from lye remedial and oxygenation. They are generally tree matured turn dark brown or black in nature. They are used for oil but the rest are salt-cured and packed in olive oil or in a vinegar solution.
