Yes, almonds do go bad. They are highly prone to rancidity.

Omega 3-fatty acids are healthy fats that can reduce the risk of heart diseases, high cholesterol levels, and inflammation in the body (*)

How To Tell If Almonds Have Gone Bad?

Please note that all of the shelf life we’ve shared with you is just estimates.

To ensure that your almonds are still fresh, you must inspect them before snacking on them. Here are some of the signs that you should look out for:

1. Mold or Discoloration

Is there a fuzzy green or white growth at the surface of the almonds? Or are there dark spots?

If there are, we highly recommend that you throw them out since there’s a low risk of getting sick when you consume mold. (*)

2. Off Smell

You already know what they should smell like. However, the nuts might not be fresh anymore if they smell differently when you open the pack.

If the nuts already smell like nail polish, old plastic containers, or paint, discard them immediately.

3. Bitter Taste

You can give the nuts a taste if you’re still unsure. But please keep in mind that you should take only a small bite.

If they already taste bitter or sour, it’s already rancid. We highly recommend that you dispose of them as soon as possible if this is the case.

How to Store Almonds the Right Way

If you wish to preserve the almond’s freshness for as long as possible, the best thing that you can do is to store the almonds properly. You can do that by following these tips:

1. Store almonds in a dark, dry, and cool place.

The best way to prevent the fats in almonds from oxidizing is to protect them from heat, light, and air. Of course, you should keep them in a dark, dry, and cool place to do this.

Fun Fact:

The colder the storage temperature, the better it is for the nuts.

That’s why you shouldn’t store almonds just in your kitchen pantry. Instead, the best storage for them would be inside your refrigerator.

2. To extend their shelf life, place them in the freezer.

Doing so would help prolong their freshness by a few months.

Pro Tip:

This is the best storage practice for raw almonds.

3. Place them in an airtight container.

This is highly recommended to keep air away from the almonds. If you plan on storing them in the freezer, make sure to put them in a resealable freezer-safe bag.

4. Keep them away from smelly food items.

They can easily absorb the odor of other foods, especially smelly food items like onions and spices. Because of this, make sure that you place them far away from these food items.

Pro Tip: When choosing in-shell almonds, go for those with white-creamy spots all over the shell and avoid those with yellowish shells.

When you do, and you hear the nut rattling inside the shell, the nut is already old and shrunken. If not, the nut is still of its best quality.
