How Long Do Green Olives Last in the Refrigerator After Opening?

By Staff WriterLast Updated March 30, 2020

Properly stored in the refrigerator, an open jar of green olives can last for approximately 3 to 4 months past the sell-by date. When left in unopened condition and in a kitchen pantry that is cool and dark, a jar of green olives can last as long as 2 years past its sell-by date.

Although technically a fruit, the inherent bitterness in an olive qualifies it as a vegetable. Olives range in color from green to black and the majority of the ones grown in the United States come from California. Green olives are pitted and then fermented in a brine before being stuffed with a sliver of sweet red bell pepper known as a pimento.
