How long can almond milk be unrefrigerated?

Almond milk has become a popular plant-based milk alternative in recent years. With its creamy texture and nutty flavor, many people enjoy using almond milk in their coffee, cereal, or smoothies. But there seems to be some confusion around whether almond milk needs to be refrigerated or not. Can it sit out at room temperature, and if so, for how long before it goes bad? Let’s take a closer look at how to store almond milk properly and how long it lasts when unrefrigerated.

How to Store Almond Milk

The best way to store almond milk is in the refrigerator. Unopened, commercially packaged almond milk will typically last for several weeks past the “best by” date when stored in the fridge. Once opened, it’s best to use almond milk within 7-10 days. The refrigeration helps slow the growth of bacteria and extends the shelf life. When ready to use, give the carton a good shake first, as the almond milk can separate a bit when sitting.

Some people wonder if it’s necessary to refrigerate almond milk after opening. Especially if you go through it quickly, you may be tempted to leave it out on the counter. However, dairy and plant-based milks can spoil more rapidly at room temperature. Refrigeration is the best way to maximize the shelf life and prevent spoilage.

How Long Does Almond Milk Last Unrefrigerated?

If almond milk is left unrefrigerated, how long does it last before going bad? Here are some general guidelines on shelf life when left out of the fridge:

• Unopened almond milk: Up to 7-10 days past the “best by” date.
• Opened almond milk: 4-6 days.
• Almond milk frother pods: 3-4 days.

These timelines can vary based on the type and brand of almond milk. Always check for signs of spoilage before consuming.

Signs Almond Milk Has Gone Bad

Here are some tips on how to tell if your almond milk has gone bad and needs to be thrown out:

• Smell: Almond milk that has spoiled will have a sour, curdled smell.
• Appearance: Look for separation, curdling, or whey. Fresh almond milk should have a creamy, uniform consistency.
• Texture: Spoiled milk may have chunks or clumps rather than a smooth pouring consistency.
• Taste: Rancid, sour notes are a clear sign almond milk has turned.
• Expiration date: If it’s passed the “best by” or expiration date, err on the safe side and toss it.
• When in doubt, throw it out! Don’t rely on smell or taste alone.

Does Spoiled Almond Milk Make You Sick?

Drinking almond milk that has gone bad is unlikely to cause serious illness in generally healthy people. However, it can lead to some unpleasant digestive upset like:

• Nausea
• Vomiting
• Diarrhea
• Stomach cramps
• Bloating

The bacteria and mold that causes almond milk to spoil can irritate the digestive system. Children, the elderly, pregnant women, and those with compromised immune systems are most at risk of adverse effects from consuming spoiled milk.

Tips for Storing Opened Almond Milk

To help maximize the shelf life of opened almond milk:

• Keep it refrigerated at all times until use.
• Screw the lid on tight to prevent leaks or spills.
• Store it on an interior fridge shelf, not the door.
• Finish within 7-10 days of opening.
• Don’t return any unused milk back to the fridge.
• Keep the fridge temp at or below 40°F.
• Check the smell and appearance before consuming.

Does Freezing Extend the Shelf Life?

Freezing is an excellent way to extend the shelf life of almond milk. It pauses bacterial growth that can lead to spoilage. To freeze:

• Make sure the container is freezer-safe if freezing in the original packaging.
• Leave about 1/2 inch of headspace to allow for expansion.
• Seal tightly and label with the date.
• Freeze for up to 6 months.
• Thaw in the refrigerator before using.
• Use thawed within 1 week.
• Do not refreeze after thawing.

The freezer can buy you significantly more time to use up leftover almond milk. Just make sure to smell and inspect it after thawing before consuming.

Does Shelf Life Vary by Fat Content?

The fat content can impact how long opened almond milk lasts. Here is a comparison:

Type	Fat Content	Refrigerated	Unrefrigerated
Regular	2-3g per cup	7-10 days	4-6 days
Reduced fat	0-2g per cup	7-10 days	3-5 days
Unsweetened	2.5g per cup	7-10 days	3-5 days

As you can see, full-fat and regular almond milk lasts a little bit longer thanks to the increased fat content. The natural fat helps slow bacteria growth. Just make sure to store all types in the fridge after opening.

Should You Avoid Curdled Almond Milk?

Sometimes almond milk can curdle or separate after sitting out too long. You may notice watery whey at the top with clumps or curds at the bottom. This curdling indicates spoilage.

While curdled almond milk won’t make you severely sick, it’s best avoided. The taste and texture will be unpleasant. Don’t try to remix it back together, as the bacteria cannot be reversed. Simply discard and open a fresh carton.

To help prevent curdling, make sure to refrigerate almond milk promptly after use. Acidity can also cause curdling, so stir gently when adding to hot coffee or tea.

Other FAQs

Here are answers to some other frequently asked questions about the shelf life of almond milk:

Does shelf life vary between brands?

Yes, each brand uses slightly different methods, ingredients, and processes that can impact shelf life. Always go by the date on your specific carton.

Does almond milk last longer than dairy milk?

Almond milk generally has a slightly longer shelf life than regular dairy milk. But for maximum freshness, both should be refrigerated.

Can you microwave spoiled almond milk?

No, microwaving will not make spoiled milk safe to drink. The bacteria cannot be reversed. You should discard and replace spoiled milk.

Is shelf life different for homemade almond milk?

Yes, homemade has a shorter lifespan of just 2-3 days. It lacks the preservatives of store-bought brands to prolong shelf life.

The Bottom Line

When stored properly in the fridge, almond milk can generally last for 7-10 days past the printed expiration date. If left unrefrigerated, it lasts for 4-6 days at room temperature before spoiling. Keep your nose and eyes peeled for signs of curdling, odor, texture changes, and separation. For maximum freshness and food safety, keep almond milk refrigerated at all times until you’re ready to pour yourself a glass or use it in recipes.
