So, you’re an olive lover—we don’t blame you! But should you be worried if you buy too many olives? Will they go bad before you can eat them? There’s a bit of debate online about this topic, but the US government states that unopened canned or jarred olives can last 12 to 18 months, while opened or fresh olives can last 2 weeks. [1] In this article, we’ll give you nothing but the facts about when olives spoil, how you can tell they’ve gone bad, and how to properly store them.

Do olives go bad?

Yes, olives can go bad. Unopened olives in liquid typically last 12 to 18 months in a cool, dry place. Open or fresh olives can last up to 2 weeks in the refrigerator if stored in an air-tight container. Olives are bad if they have a rotten smell, a sour or foul taste, or have a fuzzy or moldy appearance.

    If you leave a can or bottle of sealed olives in the pantry after purchasing them, they’ll typically last up to 18 months. If you’ve opened a can or bottle of olives, they can last up to 2 weeks in the refrigerator if stored properly. Fresh olives from an olive bar can also stay for about 2 weeks in the fridge. [2]
    • If you bought your olives in a jar and they were in the store's refrigerator section, make sure to place them in the fridge when you get home.
    • A “Best if Used By/Before” date determines when a product has the best flavor. It does not indicate when the product has gone bad. [3]

    Once you open a can or jar of olives (or get them from a self-serving olive bar), they can last up to 2 weeks in the refrigerator as long as they’re in an air-tight container. [7] Either twist the lid back onto the jar or dump the olives into a reusable kitchen container with a lid.
    • Retain as much of the brine or oil the olives are in if transferring them into another container. This helps keep the olives fresh.

    When buying fresh olives, you may want to opt for whole olives rather than pitted olives. Pitted olives can be a time saver but can be saltier and mushier. That’s because the brine (juice the olives are in) can soak through the inside of the olive since the pit isn’t there.

    Self-serve olive bars can be a wondrous sight for an olive lover, but there are a few precautions to take to choose the best olives. Pick olives that are fully submerged in brine, as these will have the best flavor. [12] Also, when scooping olives, check to ensure there are no signs of mold on the olives: white specks or discoloration.
    • Pro Tip: Ask a worker near the olive bar when the olives are restocked throughout the day. This way, you can pick olives when they’re the freshest.

    Stone fruits or drupes are fruits that have pits in the middle of them. The flesh around the pit is edible, but the pit that holds the seeds of the fruit is not. [13] Being a stone fruit, olives are the cousins of peaches, cherries, plums, and apricots. Some olives have a fruity and sweet flavor, while others are smoky or buttery. [14]
    • Fun Fact: There are more than 1,000 olive varieties, and most olive trees grow in the Mediterranean region. [15]
