So, how long do olives last? It depends on the type, but generally, green olives can last up to 6 months when stored properly, while black olives can last up to 12 months. Marinated olives, on the other hand, can last up to 2 years when stored in the fridge.
But, let's get real, who hasn't had a jar of olives sitting in the pantry for, ahem, a bit too long? Don't worry, it's an easy mistake to make, and you can still use them, just make sure to check for any visible signs of mold or slime. If they're still good, you can use them in a pasta sauce or as a garnish for your favorite cocktail.
