Does Almond Milk Go Bad? A Guide to Freshness and Safety

Quick summary: Yes, almond milk can go bad. Proper storage, checking expiration dates, and paying attention to signs of spoilage such as strange odor, taste, or texture are important to ensure its safety and freshness.

As its name suggests, this milk is made from almonds. It has very few links to the original cow’s product, except it is a similarly white creamy color and thick like natural milk. It is an excellent choice for all those who are lactose intolerant or vegan.

It has low-calorie content and numerous nutritional benefits, so it is not surprising that it is becoming increasingly popular in the daily diet of many. But what are the durability characteristics of this product, and how is it best stored? We provide all the answers below. 

How Long Almond Milk Lasts?

Similar to the cow product, here we have two versions of store bought almond milk you can find on sale. The duration depends, of course, on what type of product you choose. So let’s see right away what the duration recommendations are for both.  

Refrigerated Almond Milk

This type of almond milk is found in refrigerators and must be there throughout its life. The packaging is different, and depending on the manufacturer, the duration may vary. Most often, for unopened almond milk the expiration date will be a few weeks. But in any case, after opening, you must consume milk within seven days.    

Shelf-Stable Almond Milk

This is a more durable ultra pasteurized milk with long shelf life and will probably be good for several months on the shelf. Different producers have various instructions on use by date. Just like regular milk, shelf stable cartons can stand at room temperature until you open them. After that, it is necessary to store it in the refrigerator and consume it within a week.  

Can Almond Milk Go Bad? 

Of course. Like all other products, this one can spoil. It will usually be edible a few days or even weeks after the expiration date, depending on whether it is refrigerated or shelf-stable milk, provided it is not opened. 

However, for both versions, the rule is that, after opening, you consume milk within seven or a maximum of ten days, again depending on the brand. But at any time, if you notice any strange phenomena, you should rather throw the product in the trash. Here are some indications that almond milk is spoiled.

Sign 1: The packaging is damaged 

The moment you notice that the unopened carton is damaged, no rules and instructions on the label apply anymore. Whether the box is punctured somewhere, bloated, or has any damage that may indicate that the contents are no longer the same as in production, you better throw everything away.   

Sign 2: Something smells or tastes funny 

A good old nose and tongue are still the best detectors that something is wrong with food. If the milk smells strange or has a sour and unnatural taste, you can throw it away because it is undoubtedly spoiled. Always trust your senses, as this will save you from many illnesses. 

Sign 3: The look is weird   

Almond milk has a creamy texture about the same as regular cow’s milk. It is mild in color and silky. If you notice any stains, green or brown, on the milk, it is a sign that it is probably moldy. Also, if the texture is somehow slimy or has some bumps in it, do not consume the product because that is a bad almond milk.  

Which is the Best Way to Store Almond Milk? 

As already mentioned, keep shelf-steady products on the shelf until the moment of opening, then in the refrigerator. Products packaged for the refrigerator are kept in it at all times, both before and after opening. But if, like most, you buy a dozen products, here are tips on how to preserve the quality. Proper storage is the key to durability.

Tip 1: Keep products away from the sun  

No food product likes sunny conditions. It is very wrong to store food in places where the sun reaches them. In addition to increasing their temperature and improving spoilage, it can also affect the packaging itself, which will swell from the sun. Thus the product will no longer be edible.   

Tip 2: Keep the box tightly closed  

Once you start using the product, always make sure to close the cap well after using it. This will prevent air from entering the package and slow down the decay process. We don’t have to mention that it’s not suitable for other foods to end up in your almond milk because it will undoubtedly disrupt stability.   

Tip 3: Avoid damp places 

The recommendation for most food kept at room temperature is to keep it a dark and cool place. Your pantry is probably the right choice. But speaking of which, make sure there is no moisture near the milk packaging. Sometimes pantries can be damp, and if the milk is in cardboard boxes, it will undoubtedly impair the durability.
