Expiration & Storage Tips
When does olive expire?
Unopened canned or jarred olives can last up to two years past the printed date on the package if stored properly. Once opened, olives should be kept in their original brine or marinade, covered, and refrigerated. Under these conditions, they should be consumed within two weeks for best quality. Freezing olives is not commonly done in households as it can affect the texture and flavor. However, if necessary, they can be frozen for up to six months.
How do you tell if olive is bad?
A quick visual inspection can usually tell if olives have gone bad. If you notice any mold or yeast growth in the olives or the brine, discard the entire batch. If the olives have a strange smell, like a sour, rancid, or unusually strong fermenting smell, they are likely spoiled. Remember - when in doubt, it's better to play it safe and throw them out. Also, the taste of olives that have gone bad will be noticeably off.
Tips for storing olive to extend shelf life
• Always store unopened canned or jarred olives in a cool, dark place like a pantry to extend their shelf life.
• After opening, keep olives in their original brine or marinade in an airtight container in the refrigerator.
• Try not to use bare hands to pick olives out of the jar. Use a clean utensil instead to prevent introducing bacteria to the jar.
• If you need to keep olives for a longer period, you can freeze them by first removing them from the brine, drying them thoroughly, and then placing them in a freezer bag. Remember, their texture and flavor can change when frozen and thawed.
