How Long Do Black Olives Last?




Black olives are consumed globally and mostly used to make Mediterranean meals or olive oil. Many people consider them as fruits as they originated from a fruit tree in the Mediterranean. Others consume them as vegetables due to their culinary functions.

But how long do black olives last? Black olives have a best-before-date on their label. However, most brands will last for a minimum of three days and a maximum of two years. Generally, their lifespan depends on storage conditions. Black olives will last up to a year if left unopened and stored in the pantry.

When not stored well, their shelf life reduces. 

While they have a best-before-date on their label, that doesn’t mean you must discard them on that date. You can continue enjoying this delicacy even after the date lapse if it’s are still good.

Do Black Olives Go Bad?

Yes. Black olives can spoil depending on where and how they are stored. So, if you buy them for your salads, pizza, and oil, it’s essential to know their shelf life and how to keep them for later use. 

In most cases, their shelf life depends on three factors. These include:

  • Whether opened or not
  • Storage conditions
  • Whether they have preservatives or not 

Shelf Life of Opened Olive Jar

Unopened black olives will last longer than opened ones. They can remain fresh for one year or longer if you store them on a cool and dry shelf.

Once you open the bottle, ensure you check and comply with everything indicated on the label, especially storage time. Most black olive brands will ask you to empty the jar 3-5 days after opening, and some will tell you to consume it in two weeks. But the good news is that the label has all the instructions. Therefore, once you open the jar, remember to read that tag. 

Shelf Life of Black Olives with Preservatives 

Have you seen people using a jar of black olives for months without expiring? Well, some olive brands can last up to a year when open. The main reason is that they use preservatives (brine).

When you use the right amount of brine to preserve olives, they can remain fresh for months.

There are two crucial things you should consider when adding brine to your olives.

These are:

  • Maintaining hygiene 

For food hygiene, cleanliness is critical. Ensure you use clean utensils and other items when preparing your olives. 

Also, ensure the jar you put your brine is spotless to avoid introducing germs and bacteria to it. Usually, germs in brine can make your black olives rot faster.

  • Making the brine stronger

Saltier or stronger brines are preferred as they increase the shelf life of the black olives more. So, to make your olives stay fresh for several months, use strong brine. Material para manualidades
