The very first question is, does almond milk do bad? The answer is Yes. Though it can stay stable longer than fresh cow’s milk after some time, even almond milk tends to go bad.

Therefore, I will answer your queries related to the storage of almond milk and various other questions. The following sections are written in such a way that will help you save your stomach ailments. So let’s get into it.


How Long Does Almond Milk Lasts? 

How Long Does it Last How To Store It To Extend Its Shelf Life

The shelf life of almond milk purely depends on the ways you are using it to store it.

How long does almond milk last after opening? 

In case you have opened it, it is better to finish the refrigerated almond milk within seven days.

How long does refrigerated almond milk last?

If you have opened the carton, you can place the carton in the refrigerator as it will last for 3-10 days.

Further, if you have not refrigerated it, you must consume shelf-stable almond milk for 7 to 10 days. Also, there is a variety of almond milk that is not made out of preservatives, so it is recommended to refrigerate it immediately after opening to avoid decay.

On the other hand, if you store an unopened carton of almond milk at room temperature, it can easily survive for at least 3-4 weeks even after the mentioned use-by date. This is because of its sterilization process, in which a product is first heated or dried to kill the foodborne microorganisms.

In addition to this, there is one way of almond milk which is homemade almond milk. As we discussed in the above two cases, the life of almond milk depends on the way you store it. Similarly, you can store homemade almond milk for 3 to 5 days in an airtight container in your fridge, especially in the coldest spot in your refrigerator.

For your information, there is a special packaging that uses an aseptic carton. These cartons are specifically manufactured to give a prolonged shelf life to almond milk.

Here, the fact is that sterilized almond milk is not as stable as shelf-made almond milk. Therefore, sterilized milk can sustain for less duration.

Signs of Almond Milk Spoilage | How do I know when almond milk is bad?

Though you can consume the almond milk even after its use-by date depending upon the way you store it. But you should not consume it at all if you see signs such as thicker texture, bad smell, sour or bitter taste, color change, and sometimes even an awkwardly bloated carton.

If you notice any of the following signs, it is best to avoid consuming almond milk:

1. Thick and Lumpy Texture 

There are two scenarios for lumpy texture in almond milk.

For starters, it could be due to the curdling of the milk. This happens when the milk is on the verge of bacteria development. Whenever any dairy milk begins to lose its quality. The bacteria produce extra acid that might facilitate the process of breaking the entire structure.

While the texture might seem a bit bizarre, such almond milk is safe to consume.

On the other hand, the lumpy texture could also be due to the freezing of almond milk. This can be avoided by thawing the milk and giving it a vigorous shake. Regardless, such milk is safe to drink.

2. Sour Taste 

Check for any added sweetener in the almond milk while buying. Such a feature is more prone to making the almond milk taste bitter, sour, or acidic when it goes bad. If you find any such taste, it is best to toss it out. Do not try to offset the taste by adding sugar, as it can directly affect your health.

3. Bloated Carton 

If your almond milk carton is unopened and packed, it is best to check the carton. If it seems bloated, it is advisable to toss it out.


Bloating is considered to be a clear indication of the presence of bacteria in the container. It feeds on the contents and produces gas. Since this gas does not have any way out, it makes the packet bloat.

4. Change in Color 

Discoloration is said to be one of the most evident indicators of spoiled almond milk. If it is yellow, consider it to be expired.

Always remember that almond milk is supposed to be off-white. If you see any other color, it is best to discard it.

5. Black Patches 

Black patches in the carton of the milk are a sign of mold. Generally, this happens when the almond milk is not used for a long period. If you see any such signs, it is best to toss them out.

What Happens if You Drink Spoiled Almond Milk

There is hardly any difference between the spoilage of any kind of milk and almond milk. If you consume expired milk, you have a high risk of food poisoning. If it goes beyond its mentioned use-by-date, it may develop bacteria, and if you have left it open, the bacterial spores may give room to other organisms to grow.

Further, you may have other food poisoning symptoms as well, such as diarrhea, abdominal pain, cramps, and vomiting, to name a few. Besides, drinking bacteria developed in spoiled almond milk may keep you uneasy with mild discomfort that may last for quite a few hours.

Additionally, if the pain gets worse, it is better to see a doctor and get medication as soon as possible. In this matter, I want to highlight that you should not ever consume expired almond milk. For those who are allergic to dairy products or lactose intolerant, you should never even try this stunt as it may risk your life.
