How Long Does Almond Flour Last?

Over the years, gluten-free products have dramatically risen in popularity. Whether you’re on a coeliac diet or not, many people eat gluten-free foods as a part of their daily diet.

Almond flour is one of these alternatives. Many people have almond flour stored in their cupboards, using it for cookies, muffins, and cakes.

However, time goes by easily, and your new bag of almond flour might go unopened for several months.

If this has ever happened to you, you might be wondering if the nut flour is still safe to use after a few months.

So, just how long does almond flour last? We’ll cover the answer in this article, as well as how to store your almond flour so it lasts for longer.

How Does Almond Flour Go Bad?

Any products in powdered form can go bad once they’re exposed to water or pantry bugs. In almond flour’s case, water exposure leads to mold forming or flour clumping.

Nut flours are also prone to harboring insects. If there are any pantry bugs, dead or alive, you must get rid of your almond flour.

This goes the same for mold or clumps in the flour. However, if there are dry clumps within the mix, these are perfectly safe.

These should easily break with fingers or once the flour has passed through a sift. Wet clumps will not break down. They are a good sign that the almond flour has gone bad.

Almond flour goes bad the same way coconut and whole-grain flours do. These flours contain oils that go off easily.

White flour doesn’t have any of these oils, so in most cases, it can be stored away for longer. If your almond flour hasn’t gone bad already, it will do soon as it contains oils.

Always examine your almond flour well before using it. It should be beige or cream in color. Any blue or green dots are signs of mold, which mean that it should be discarded immediately.

It should also smell pleasantly nutty, but if it starts to smell sour, this means that the product has expired.

How To Store Almond Flour?

Almond flour generally lasts around a year. Most brands should print use by dates on the label, so it’s easy to know when you should throw it out by.

As long as you keep your almond flour in the right storage conditions, it should last you a while. Almond flour thrives best in a cool and dark place.

Here are some of the best ways to store almond flour.

In The Pantry

You can keep your almond flour in the pantry, but only if you haven’t opened the bag yet. Pantries are good places as they are dark and cool.

A kitchen cabinet or cupboard would be an even better choice, as they keep out light and heat well. Try to store your unopened almond flour in the darkest and coldest area of your kitchen.

In The Refrigerator

After you’ve opened your almond flour, you must seal the bag back up after you use it. Once you’ve done this, it’s best to keep your almond flour in the fridge.

If your bag is put back in the pantry, the flour can attract bugs that thrive in that environment. These bugs are normally found in nut-based foods.

The fridge also keeps the almond flour cool, prolonging its freshness.

Before you place your almond flour in the refrigerator, it’s important to put it into an airtight container.

Cold temperatures attract moisture which can form wet clumps and mold. Aim to keep your almond flour in the coldest areas of the fridge.

Can Almond Flour Be Frozen?

Yes, almond flour can be frozen! Freezing your almond flour is the best way of prolonging its lifespan.

Unopened packages can last between 1-2 years, whereas opened bags last between 6-12 months.

If you want to go about this route, be aware that it can be tricky to freeze powdered products. Begin by freezing a small amount of almond flour.

If this went well and there were no difficulties, you can freeze the rest of your product in the same manner.

Almond flour usually comes in sealed plastic packaging, which is ideal to keep in the freezer. In this case, you won’t need to transfer the flour to another container. Simply place the sealed bag in the freezer.

If you have opened your almond flour bag, place it within a freezer bag so that the cold temperatures don’t affect the product. Wrapping it twice in this way can also prevent the flour from losing its fine consistency.

Before you use your frozen almond flour, leave it out for an hour until it reaches room temperature. This avoids any texture changes or clumps when you use it again.

How Long Does Homemade Almond Flour Last?

Homemade almond flour shouldn’t be kept any differently from store-bought varieties.

The same rule applies, keep it in a dark and cold area. As long as you take care of your homemade nut flour, it should last you a while.

Even if you have made your flour by yourself, you should always check it for mold and bugs.

Store-bought nut flours may have preservatives that help keep them fresh. Homemade flours won’t have these, so they may go bad quicker than branded ones.

Are Almond-Meal And Almond Flour The Same?

This is a common question. Almond flour is found regularly now, but it can still be hard to find.

This led many people to substitute almond meal for flour in recipes. However, almond meal and almond flour are different products.

Almond meal is made from raw almonds that have been ground down.

Almond flour is lighter in color, as it’s made from peeled and blanched almonds. These have been ground even finer to resemble flour.

There may be some recipes that won’t matter if you use either product. However, using almond meal may make your bakes cakey or clumpier in texture.

To be on the safe side, always use almond flour when the recipe calls for it.

In Summary

Almond flour is a fantastic gluten-free alternative to wheat flour. However, as it contains oils, it can go bad easily if it isn’t stored properly.

Nut flours do well in a cool and dark place. Keep unopened almond flour in the pantry. Once it has been opened, transfer it to an airtight container and place it in the fridge. If you want to make your almond flour last even longer, you can do so by freezing it for long-term use.
