Do Olives Need to Be Refrigerated?

In most cases, it’s a good idea to refrigerate the olives. Storing olives in the fridge prolongs their shelf life, even if the label doesn’t explicitly recommend it. Refrigerating them slows down the spoiling process and keeps them fresh for longer.

If you have opened the jar of olives, then you must always refrigerate them. If you don’t plan to use the olives in a jar immediately after opening, it’s best to store them in the fridge.

However, if the olives are submerged in their brine, you can store them at room temperature. Just make sure to keep them out of direct sunlight and heat.


Can Olives Be Left Unrefrigerated?

Yes, but not for long. Opened olives without brine can be left unrefrigerated for 3-5 days. The ideal storage conditions are necessary to preserve them. If stored improperly, they will go bad within just 2-3 days.

Unopened olives, on the other hand, can be kept at room temperature without any problem. When storing olives at room temperature, make sure that the jar is not exposed to any sources of heat, e.g. stovetop, direct sunlight, etc. The constant exposure to heat or light will spoil them very quickly.

If the olives are submerged in their brine, they can be left unrefrigerated for months. You will need to follow the same protective measures, i.e. keeping them out of direct sunlight and heat. After opening, it’s best to consume the olives within 3 weeks.


Do You Have to Refrigerate Kalamata Olives After Opening?

Do Unopened Olives Go Bad?

Yes. Even when unopened, olives have a limited shelf life. However, they can last for a good amount of time, sometimes even past their printed date, if stored properly. You only need to worry about their shelf life when the jar has been opened.

Even then, they can last from a few weeks to months if stored in the fridge. The shelf life of unopened olives varies depending on the preservation method, the storage method, and the type of olives.

Generally, olives preserved in oil have a longer shelf life as compared to those preserved in brine. But once the jar is opened, the shelf-life for both is pretty much the same.


Do Black Olives Have to Be Refrigerated After Opening?

If the jar has been opened, then you will have to refrigerate black olives to prevent spoilage. Once you have opened the jar of black olives, store them submerged in their own liquid in a glass or plastic container in the fridge for 1 or 2 weeks.

There are some manufacturers that state that there’s no need to refrigerate black olives after opening if you handle them correctly.

How Do You Store Olives?

The recommended storage methods vary depending on various factors. If you want to store unopened olive jars and cans, then the pantry is an excellent place for them as it is dark, dry, cool, and free of sunlight. Unopened olives in brine can be preserved for a long time but the length of time depends on the preservation technique used.

If the jar has been opened, then the best place to store olives is in the fridge. Simply tighten the lid to make sure that the olives are submerged in the liquid and then refrigerate them.

If you accidentally spill out the liquid, use 1/2 teaspoon of salt and a cup of water to remove it. Always use clean utensils or spoons when taking out the product to minimize the risk of cross-contamination.


Can You Eat Olives That Have Been Left Out?

Yes. If the olives haven’t been left out for too long, it’s probably okay to eat them. Just be sure to check for the signs of spoilage before proceeding.

If mold or white film has developed, simply pour out the film by tipping over the jar. You can prevent this film from forming by adding a teaspoon of vinegar to the jar. The olives should be safe for consumption.

However, if they taste bad, discard them. You should also avoid eating olives that have a bad odor, color, or texture. Similarly, if the top of the lid on the can or jar is dome-shaped or rounded instead of flat across, it is likely that olives have gone bad because the jar wasn’t sealed properly. Lastly, if you see slime or mold under the brine, it’s best to discard the olives.


In summary, Olives make an excellent ingredient for many dishes, and they even taste great on their own. They come in many varieties and colors, such as green, black, purple, and brown. Additionally, they are used to make olive oil, which is a staple of the Mediterranean diet.

Olives have a long shelf life and don’t go bad easily. They may lose their crunchiness over time so to keep them fresh for as long as possible, you should store them properly.
