chosen: Different varieties of olives are best preserved in different formats. Green olives need to breathe to maintain their crisp texture, so they are usually packaged in jars. Black olives are fermented in salty brines, so they are better preserved in cans, which are designed to retain moisture. The higher salt content of canned black olives also gives them a stronger taste.
