How Long Do Olives Last?

When it comes to olives, how long do they last? If unopened, olives can keep for 1-2 years past the “best by” date. The shelf life of olives is determined by a number of factors, including the best by date, preparation process, and storage method. Please read the entire article before making a purchase decision. 

Olives are technically a fruit because they grow from a small Mediterranean fruit tree, but they are commonly considered a vegetable for culinary purposes due to their bitter taste. The majority of olives farmed in the United States are currently grown in California and then fermented to minimize bitterness. To improve the flavor, most green olives are packed with tiny red pimento or sweet pepper.

They come in a variety of colors, ranging from green to black. 

So, do olives go bad after a while? Olives do survive a long time, but how long do they last? Olives have a recommended shelf life of up to a year. If stored correctly they’ll pass their best before date.

Unopened/sealed olives last for 1-2 years (past their best before dates). While opened ones will last about 3-4 months in the refrigerator. Olives can be frozen for about 1-2 years.

How do you know when olives go bad?

The best way to tell whether your olives have gone bad is to use your sense of smell. If the olives are becoming rotten, they will emit an odor. If spoilt, their texture and color may alter, and they may grow mold. 

If the top of the jar or its lid is circular and shaped round, rather than flat across, the olives have most likely gone bad due to a lack of adequate sealing. The seal has been broken if you open the jar and do not hear the typical pop.

Foodborne diseases can be avoided by following proper cleanliness and food safety procedures. Of course, there are some health hazards linked with rotting goods, so always remember to practice food safety and consume your food before its expiration date!

How long do olives last at room temperature?

Generally and most commonly, olives come packed in jars and sealed to keep longer. They do not perish easily as they are fermented already and they have preservative water in them. This makes olive last longer on the counter, therefore unopened/ sealed olives can last 1-2 years in the pantry. While opened ones or the ones that have their seal broken already should be refrigerated.

How long do olives last in the fridge?

After opening the olives, keep them refrigerated. Liquid-free olives can last up to three days in the fridge once opened. Liquid-packed ones usually last at least a week or two but can last much longer if properly stored. If properly stored they will meet up with the recommended time which is about 3-4 months. Just make sure they’re submerged in brine or whatever liquid they’ve arrived in and they are stored where it’s chilly and there is air radiation, like the crisper drawer. 

Can you freeze olives?

The good news is that freezing olives is doable. Frozen olives, for example, can keep their flavor and texture for up to a year. Olives can be kept fresh for up to three weeks after being thawed in the fridge. However, you do not simply place the can of olives in the freezer. The fruit can be frozen in a variety of ways. 

Here’s one way to keep it frozen. 

  • Begin by placing the olives in a colander and running water over them. This would clean the fruit of contaminants. Allow 10 to 15 minutes for the fruit to drain dry. Keep in mind that too much water will generate dampness in the olives, which will damage their flavor. If you can’t wait, you can dry the olives with a paper towel.
  • When the olives are completely dry, place them in a clean, freezer-safe container. Make sure there’s enough room between the olives and the lid, though. At least half an inch of space should be provided to allow for the expansion of the fruits when they are frozen. Before putting the container in the freezer, make sure it’s airtight. We recommend putting the olives in the freezer’s center, where the temperature is stable like you typically do when storing goods. 

Using Brine to preserve olives before freezing them:

You can soak them in brine, which is a strong salt solution. This method will prevent the olives from softening due to freezing. Although you will be soaking the olives in a brine first before freezing them, this process is similar to the previous trick I provided.

The following is a step-by-step tutorial to implementing this method: 

  • Pour a brine made with four ounces of salt per gallon of water over the olives in a pan. Cook for 10 to 15 minutes at a low temperature. 
  • Remove the olives from the brine and place them in cold water. 
  • After removing the olives from the water, place them in a freezer-safe container.

How long does it take to freeze olives?

Freezing olives shouldn’t take long; an olive can be frozen in as little as 2-3 hours. If it isn’t completely frozen after this time, consider leaving it for a few more hours or overnight. 

How long can you keep olives in the freezer? 

Olives can be frozen for 1-2 years and will keep them fresh. As long as they froze well and the freezer bag isn’t ruined, they’ll be okay to eat. Olives can be consumed after this time if they are frozen properly, but it is best to stick to the specified time range to avoid over-freezing. 

Frozen olives offer a great healthy snack that may be eaten after thawing.

Best way to store olives?

Olives last for a year or two when they’re new or unopened on the kitchen counter. It might not be so necessary to freeze them when they’re unopened. However, if they’re opened, they can last for about 1-2 months in the fridge, when they are stored well. But to keep them for longer, they can be frozen for up to a year or two.
