How Long An Open Carton Of Almond Milk Should Last In The Fridge

While the dairy aisle is well-stocked with many types of milk, almond milk is the most popular non-dairy alternative to cow's milk in the U.S., according to Morning Consult — and we get why. In addition to its creamy taste, almond milk is generally lower in calories and fat compared to cow's milk and is a great source of vitamin E. Plus, it's usually fortified with vitamin D and calcium, making it a healthy alternative for vegans, lactose-intolerant individuals, and anyone who prefers the taste over cow's milk. As a result, almond milk can be a fantastic substitute for dairy in all kinds of recipes, from non-dairy soups to baked goods.

However, as beloved as almond milk is, not many people know when exactly it goes bad. Similarly to cow's milk, there can be signs that a carton of almond milk has overstayed its welcome in your fridge, such as changes in scent, flavor, and consistency. But there's also a firm timeline for when you should absolutely pour it down the drain and open a new carton. So how long does almond milk last once opened? Provided it's stored in the fridge after opening, a carton of almond milk will remain safe to consume for seven to 10 days, according to the FoodKeeper App, a food safety resource developed by the USDA.

Almond milk is sold in two forms: a shelf-stable carton that doesn't require refrigeration before opening, and a carton that's already refrigerated when you buy it. If you don't drink almond milk often, the shelf-stable carton is the best choice as it lasts much longer when unopened. However, once you've cracked the seal and poured a glass, both types stay fresh for the same amount of time.

The exact timing comes down to your senses. Like cow's milk, almond milk will start to smell and taste bad or develop a clumpy texture as it spoils. Most non-dairy milks, including rice, coconut, and soy, last for the same amount of time once opened. If you use different plant-based milks for different needs, this makes it easier to know when you should get rid of them.

For those who make it themselves, homemade almond milk often spoils faster than a store-bought carton, as it doesn't go through the pasteurization process. You can expect it to last for about three to seven days in the fridge. Like store-bought almond milk, you'll want to toss it once its odor, flavor, or texture changes.

By noting when you open your current carton, you can save yourself from pouring spoiled almond milk into your morning bowl of cereal. After all, the start of the day can already be hard enough without ruining your breakfast.
