We’ll address the topic “How long can black olives be stored in the refrigerator?” and how to determine if they’ve gone bad in this post.

How long can black olives be stored in the refrigerator?

Olives from the Balkans are frequently preserved in oil. Unopened jars of black olives will keep for 3-6 months after the marked expiration date. Under refrigerated circumstances, the shelf life is reduced to 1-3 weeks or 6-12 months (for some brands) once opened.

When it comes to olives, how long do they last?

The shelf-life of olives is shown in the table below.

The shelf life of olives varies depending on how they are stored, preserved, and what sort of olive they are. Olives that aren’t brined or preserved in oil have a reduced shelf life. Stronger brines preserve food better than their weaker counterparts.

Olives that have been preserved in oil have a longer shelf life than those that have been stored in brine. The self-life of olives preserved in oil and brine is nearly same once the jar is opened.

The table below illustrates the estimated shelf life of olives based on storage and preservation methods.

How do you tell if your olives are bad?

After opening, olives must be totally submerged in their preserving solution at all times. Those that are exposed to air are more likely to spoil.

Examine the jar or can

Toss the jar/can in the trash if it’s swollen, leaking, has dents, or smells rusty. The inflated can is a sure sign that it contains germs that are generating gas.

Similarly, a leaking or broken can/jar puts food safety at jeopardy since it is more susceptible to microbial attack.

Examine the olives

Off-putting odor: When you lift the lid or can top, bad olives emit an extremely intense and unpleasant odor. Because of the metal in the can in which they are preserved, canned olives usually have a metallic odor.

Mold can grow in an opened jar or can of olives that has been sitting in the fridge or on the counter for an extended period of time.

In most cases, the colorful organic growth will be visible. Mold growth is indicated by the slimy texture of the solution in which the olives are submerged.

Rancidity is a condition that arises when olives are preserved in oil. If the jar or container has been sitting in heated temperatures for an extended period of time, the oil will become rancid.

Olive storage suggestions

An unopened jar/can of olives can last for years in the pantry or any other dark, cool location. The printed date for each brand and type of olive will give you a better idea of how long it will last. An unsealed jar of brined olives should keep for a few months.

When storing the olive jars in the pantry, ensure that the temperature remains stable and that the jar is not exposed to any heat sources such as direct sunlight or the stovetop. The taste of olives will be ruined if they are exposed to light or heat for an extended period of time.
Always keep an opened container of olives refrigerated. If the temperature outside the fridge is below 68°F or 20°C, some manufacturers allow storage outside the fridge.

It’s advisable to transfer the contents of a can of olives to a glass jar if you’re not going to use them right away. Then put the jar in the fridge.

The olives should be completely submerged in the solution, whether it’s brine or oil. If the original brine has been emptied, submerge the olives in a homemade brine solution.

To remove the olives from the jar/can, use clean, unused spoons or forks. Refrain from re-filling the jar with the leftover olives.

Between usage, liquid-free olive packets must be firmly packed. Transfer the contents of the package to an airtight jar if the original packing is not reusable.
