Expiration & Storage Tips
When does black olives expire?
Unopened canned/jarred black olives generally stay good for 1-2 years if stored properly in a cool, dark place and their packaging is undamaged. The 'best by' date on the package is just an estimate from the manufacturer, and it's common for olives to be fine beyond that date. Once opened, black olives can last for about 10 to 14 days in the fridge if kept in their brine or a solution of oil, salt, and vinegar. If frozen right after opening, black olives can extend their life up to six months. Frozen olives should be defrosted slowly in the fridge.
How do you tell if black olives is bad?
There are a few clear signs that black olives have gone bad. Bad olives often develop a strange, off-putting smell that is different from their normal tangy, briny aroma. If the olives have become slimy or moldy, or if the brine looks cloudy and discolored, you should discard them. Likewise, if the can or jar of olives is bulging, leaking, or has a broken seal, it's a strong sign of spoilage due to bacterial or fungal activity.
Tips for storing black olives to extend shelf life
• Always store unopened cans/jars of black olives in a cool, dark place like a pantry or cupboard. Avoid places with fluctuating temperatures, like near the stove or under the sink.
• After you open the can or jar, transfer the leftover olives along with their brine into an airtight container. This helps keep them fresh for longer. If too dry, they can shrivel and lose their flavor.
• To freeze black olives, place them in a heavy-duty freezer bag, making sure to remove as much air as possible before sealing. Alternatively, you can freeze them in a suitable container filled with olive oil.
• When defrosting frozen olives, take out the desired portion and let it thaw in the fridge. Avoid using the microwave or exposing to high temperatures, as it may alter the taste and texture of the olives.
