Does Almond Milk Go Bad? How To Tell If It’s Spoiled?

You’ve bought a few cartons of almond milk on a sale, and one of them still sits in the pantry. It’s past the date on the label, and you’re not sure if you can use it.

Or maybe there’s a half-open carton sitting in the fridge for a few days already.

Either way, one question comes up: does almond milk go bad?

Almond milk is one of the most popular non-dairy milk. But since it comes in a refrigerated and unrefrigerated variety, many people aren’t quite sure how to store it, if it requires refrigeration, and how long does it last.

In this article, I try to simplify all of those aspects. If you’d like to learn a bit more about almond milk, read on.

How To Store Almond Milk

Storing almond milk is similar to storing soy milk or oat milk. There are two kinds of this milk alternative available on the market: unrefrigerated and refrigerated. Let’s start with the former.

Unrefrigerated (or shelf-stable) almond milk is quite similar to unrefrigerated coconut milk or dairy milk. You should store an unopened carton in a cool and dark area, away from sources of heat.

The pantry is usually the best choice, but a cabinet in the kitchen works too. Once you open the carton, seal it tightly and keep it refrigerated.

Refrigerated almond milk needs to sit properly sealed and in the fridge at all times, that’s about it.


If you’re not sure if the nut milk you bought is shelf-stable or not, think about where it was in the store. If it was in the refrigerated section, store it in the fridge.

When it comes to refrigerating almond milk, many producers, like Blue Diamond, recommend storing it away from the door. That’s because the door is usually the warmest part of the fridge and is prone to temperature fluctuations.

Overall, before you open store-bought almond milk, you should store it like they stored it in the supermarket. Once you open the carton, you should keep it refrigerated.

You should always refrigerate homemade almond milk.

Can You Freeze Almond Milk?

Freezing almond milk is somewhat controversial.

Manufacturers, like Silk, don’t recommend it. That’s because the liquid changes its texture after thawing, and it’s definitely not as good as it was before freezing.

But many people, especially those who use almond milk only for baking, freeze the leftovers to avoid waste. Plus frozen and thawed almond milk works fairly well in baked or cooked recipes.

In such dishes, the change of texture isn’t that noticeable and doesn’t affect the quality of the end product that much.

Freezing almond milk for drinking purposes isn’t a good idea, as the change of consistency makes the liquid unpalatable for most.

Overall, feel free to freeze almond milk for cooking and baking. And check out our guide to freezing almond milk for more details.

How Long Does Almond Milk Last

Let’s start with shelf-stable almond milk. This variety usually comes with a best-by or best-if-used-by date on the label. That date is an estimate of how long the milk will retain its freshness.

Of course, since this liquid is shelf-stable, it will usually last beyond that date.

How long does shelf-stable almond milk last past the printed date?

It’s difficult to say, but you shouldn’t expect it to stay fresh for longer than a month or two. Beyond that period it’s probably better to discard the liquid right away.

Once you open the carton, it can sit for about 7 to 10 days in the fridge.

Refrigerated almond milk usually comes with a use-by date.

The use-by date is printed on refrigerated products, and it’s much more strict than a best-by date. That means that an unopened carton of this nut milk can last only a few days up to a week past the use-by date.

Once you open the container, you have about a week to use its contents before it spoils.

When it comes to homemade almond milk, you should use it within 3 to 4 days. Store-bought varieties are pasteurized, so they last longer in the fridge than the one you make yourself.


Always keep open almond milk refrigerated. If you leave the milk out at room temperature for an hour or two, it’s most likely perfectly fine. But if you accidentally left it out overnight, it’s better to discard it.

Almond milk (shelf stable, opened) 7 – 10 days
Almond milk (refrigerated, unopened) Use-by + 5 – 7 days
Almond milk (refrigerated, opened) 7 – 10 days
Homemade almond milk 3 – 4 days

Please note that the dates above are approximate.

How To Tell If Almond Milk Is Bad

There are a few signs of spoilage of almond milk.

First is an unusually bloated carton. If that’s the case, throw out the milk.

Now pour half a glass of this dairy-free milk and give it a sniff and a good look.

If the smell isn’t fresh and nutty anymore, discard the milk. Same thing if you notice any lumps or discolorations in the liquid.

If everything seems to be perfectly fine, give it a taste. If it tastes okay, feel free to use this milk. Otherwise, it’s past its prime, and you should get rid of it.

Of course, going through the process outlined above makes sense only if the date is within a reasonable period.

If the almond milk is already opened for two weeks, just toss it out. Same thing if it’s 3 months past the best-by date.

The first signs of spoilage are impossible to spot, so it’s safer to cut your losses and assume it’s spoiled.

  1. If I buy the almond milk refrigerated, and keep it that way, it seems to be fine, months after expiration. Thanks for the info!

  2. Some almond milk containers say to use within a week, Silk does not. I think it is to sell more of the product. I enjoy this product and am happy with this information so now I can tell if it in fact goes bad that quickly unopened. With Silk brand I was concerned it was a Monsanto product but after reading about it I am pretty sure it is not. I used to use soy but enjoy the taste of choc almond milk so much more and I believe it is safer (for me) in regards to soy and hormones. Thank you for the information provided here.
    If you like chocolate as much as I do try dark chocolate Silk almond milk. It works great for smoothies also.

  3. I have found most times that almond milk stays fresh an unusually long time until this last carton. It came out thicker than normal and didn’t taste bad and I had just eaten refrigerator oats made from it the night before. I got lucky.

  4. I just opened my bottle of almond milk last week. We store it in the refrigerator. Today, the insides of the container has black residue and the milk itself is a bit chunky….but before you jump to conclusion, I want you to know that it tastes and smells GREAT! Even yummy. Do you think it is still spoiled?

  5. I’m drinking some Almond Breeze Reduced Sugar right now that’s been in my refrigerator around 5 months. It still looks, smells and tastes the same as when I opened it. I’ve often kept refrigerated almond milk weeks or months after the date on the carton and never had one go bad during that time.

  6. I drink Almond milk almost everyday. Especially in my morning smoothies. It will go bad after opening. Twice now, I have gone several days without my regular toast and smoothies breakfast, to come back to it and not checked the almond milk for freshness. Once it is opened be very, very careful! The first time it only lasted about four hours, but I had nothing left in my stomach when it was over. The second time was much, much worse. Started throwing up in just a couple of hours and continued that for over 2 hours.n it included clammy skin, severe cramping and nausea. Then it got worse! The clammy skin turned into dripping sweat, soaking my clothes and although the throwing up slowed, diarrhea started and was uncontrollable. I lost any strength I had by then and thank goodness my husband was home or I would still be on the bathroom floor. He was able to put some nausea medicine under my tongue and I was able to finally get under contol. Sorry to be so graphic but those who drink alternative milk need to pay attention after it is open! It does go bad and FOOD POISONING is real!

  7. Was checking around to see how long opened almond milk was REALLY good for. I opened mine on July 31. Today is August 29 and I am still drinking from this same carton. I only use about a cup once or twice a week to make a cocoa almond smoothie (on my diet plan). I’ve had some issues, but I think it may be more from the Xylitol (from birch) that may be affecting my stomach. I don’t notice anything unusual with the almond milk, so I keep using it. There’s probably less than a cup left at this point, so I may just pour the rest out since it will now be another week before I can use it again. I just hate wasting anything, but I don’t want to be sick either!

  8. I have a tetra box of Natura Unsweetened Almond milk, kept in the pantry. Best before date is about 1.5 months ago. I tasted the milk, it was fine, but unflavourful. There were little white particles that appeared after I shook the contents. It did not smell spoiled.

    I needed a bit extra for an overnight recipe for groats, but decided to err on the side of caution and avoid ‘food poisoning’.

    Will keep the milk for usage myself, but not to share with my children.
