Does Almond Milk Go Bad? How Long Does It Last and Ways to Tell if It Has Gone Rancid

Almond milk, like all milk products, can spoil: when it's unopened shelf-stable it can last months in a pantry, while once opened it should be refrigerated and used within 7-10 days. Spoiled almond milk smells sour, has a lumpy texture, and tastes off. Drinking it can cause digestive issues.

All types of milk products, whether dairy or non-dairy, have an expiration date. While detecting spoiled dairy milk is straightforward—usually, a quick whiff will tell you all you need to know—non-dairy alternatives like almond milk can be trickier. Almond milk, made by blending almonds with water and then straining the mixture, is a popular dairy-free option. But how long does it last? And can you drink it after its expiration date?

How Long Does Almond Milk Last?

Unopened almond milk can last for several months past its production date, especially if it's shelf-stable. Shelf-stable almond milk can be stored in a pantry or any cool, dark place until opened. Once opened, it needs to be refrigerated and typically lasts 7-10 days. Refrigerated almond milk, however, should always be kept in the fridge, unopened or not, and follows the same 7-10 day rule once opened.

How to Tell if Your Almond Milk Has Spoiled

Identifying spoiled almond milk requires a bit more attention than its dairy counterpart. First, check for any changes in smell—spoiled almond milk often has a sour or off odor. Look for changes in texture; if the milk is lumpy or has separated significantly, it's time to toss it. The taste will also be a giveaway—rancid almond milk tastes sour and unpleasant. So, if it doesn't taste right, don't drink it!

What Happens if You Drink Expired Almond Milk?

Drinking expired almond milk, or milk that has gone bad, isn't the best idea. While it might not be as immediately risky as spoiled dairy milk, it can still lead to digestive discomfort, such as stomach cramps or diarrhea. The severity can vary depending on how far past its expiration date the milk is and your personal tolerance.

Wait… What If I Freeze It? Can I Do It?

Yes, almond milk can be frozen, but it's not always recommended due to potential changes in texture and flavor. When stored in the freezer, almond milk can last for up to three months. However, upon thawing, it may separate or become grainy. To minimize these effects, thaw it slowly in the refrigerator and shake well before using.
