Does Almond Flour Go Bad?

Almond flour is often used as a substitute for regular flour because it’s gluten-free, low in calories, and minimally processed. But does almond milk ever spoil?

It is made from powdered almonds, which is why almond flour tends to go bad more quickly than other flour products.

You see, almonds contain a high amount of plant-based oil. And as you know, oil can go rancid quickly when exposed to heat and direct sunlight. Often, almond flour is made from blanched almonds, and the process itself may affect the product’s shelf life as well.

That being said, almond flour doesn’t contain moisture, and this helps extend its shelf life. As long as you keep the product sealed and stored away from heat, it should stay okay to use for a long time.


Almond flour is yet another almond-based product that’s gaining popularity recently. If you’re interested in others, we have a guide on how long does almond milk last and an article that tries to answer the question: can you freeze almond milk?

How to Store Almond Flour?

Storing almond flour is similar to storing coconut flour, and not exactly the same as storing wheat flour.

Storing Almond Flour in the Pantry

As long as the almond flour is unopened, you can store it safely in the pantry. Keep the product away from heat and light. If you can, store this product in a kitchen cabinet or perhaps, a cupboard. The darker the storage area is, the better.

After opening the package, make sure to keep it closed after every use.

At this point, you can consider storing the almond flour in the fridge. Why? Two reasons. First, almond flour attracts bugs or “pantry pests.” These critters usually breed in nut products. Second, storing almond flour in the fridge is recommended for freshness.

Storing Almond Flour in the Refrigerator

A fridge is a great place for storing opened packs of almond flour, as well as stretching the shelf life of almond flour that’s nearing its best-by date.

But before you put powdered almonds in the refrigerator, we recommend transferring the product into an airtight container. Chilly temps tend to draw moisture into the product and cause powdered products to clump. That’s why it’s crucial to always seal the container after every use. Store this product in the coldest spot in the fridge.

Can You Freeze Almond Flour?

That’s right; you can also freeze almond flour. When stored in the freezer, this product will keep almost indefinitely.

Of course, freezing powdered products is always tricky, so I highly suggest freezing a small batch of almond flour first. If you didn’t come across any issues, then you can freeze the rest of your stash.

You can often buy almond flour in sealed plastic packaging, so no added prep is needed to freeze this product. Just chuck it in the freezer. But for opened packs of almond flour, use a freezer bag to protect the product from the freezing temps. Double wrapping also helps minimize changes in texture or consistency.

When using frozen almond flour, make sure to let the product sit until it comes to room temperature before using it. This will help prevent clumps.

How Long Does Almond Flour Last

Almond flour that’s stored in the pantry will keep for at least a few months pst the best-by date on the package. Transferring it into the fridge will give it another few months. When it is frozen, almond flour will stay safe to use indefinitely.

Please note that all frozen products deteriorate in quality very slowly, so even though almond flour can stay in the freezer forever, the earlier you use it, the better the quality.

How to Tell If Almond Flour Is Bad?

It is easy to tell if a pack of almond flour has gone bad. When it’s fresh and usable, almond flour has a pleasant, nutty aroma and a loose consistency. It is also beige or cream in color.

But if it has gone bad, it will take on an off-aroma. Its color will change too. Changes in color, texture, and aroma are a sign that the product may have spoiled. The same thing goes for mold growth. If you see specks of bluish-green over the powder, discard the product immediately.

You should also check if the product is infested by bugs or any flour worms. Nut flours attract certain insects, and even if it’s still usable, the presence of bugs means it’s time to toss the product in the trash.

Almond Flour FAQ

Does almond flour need to be refrigerated?

Although the fridge is the recommended storage method for almond flour, it doesn’t require refrigeration to stay fit for use. Keeping this nut flour in cold temperatures simply extends its shelf life.

If you use each bag of almond flour way before the date on the package, there’s no need to refrigerate it.

Can I use almond flour past its expiration date?

The date on the package is usually a “best by” date, which is not an expiration date. As already noted, almond flour can be stored for way longer than that date.

As long as the powdered almonds don’t show any signs of spoilage described earlier, it should be fit for use. Of course, if you’ve found the bag or package stored in bad conditions for God-only-knows how long, tossing it away is also a reasonable option.
