How Long Does Cashew Milk Last In The Fridge

Cashew milk lasts in the fridge for about 7 to 10 days after you open it.
 
That’s the quick answer if you’re standing in front of your fridge right now wondering whether that carton is still good.
 
Homemade cashew milk is a little different and typically keeps for 3 to 5 days in the fridge.
 
If you’ve been asking how long does cashew milk last in the fridge, the short answer is: it depends on whether it’s store-bought or homemade, and whether it’s been opened.
 
In this post, we’ll break down exactly how long cashew milk lasts in the fridge, the signs it’s gone bad, and how to store it so it stays fresh as long as possible.
 
Let’s get to it.

How Long Does Cashew Milk Last in the Fridge?

How long cashew milk lasts in the fridge depends on a few key factors, but here’s the general breakdown:

1. Unopened Store-Bought Cashew Milk

An unopened carton of cashew milk usually lasts until the printed expiration date, which can be anywhere from a few weeks to a few months when kept refrigerated.
 
Shelf-stable cashew milk, on the other hand, can sit in your pantry unopened for months and only needs refrigeration once you open it.
 
Just always check the label, because brands vary in how they process and preserve their cashew milk.
 
 

2. Opened Store-Bought Cashew Milk

Once you open a carton of cashew milk, it typically lasts 7 to 10 days in the fridge.
 
That’s why most cartons say something like “best consumed within 7 days of opening” right on the packaging.
 
Opened cashew milk lasts in the fridge for about a week because exposure to air introduces bacteria that slowly spoil it.
 
So mark the date you opened it and try to use it up within that window.
 

3. Homemade Cashew Milk

Homemade cashew milk lasts in the fridge for only 3 to 5 days.
 
That’s because homemade cashew milk has no preservatives, so it spoils faster than the store-bought kind.
 
Store homemade cashew milk in a sealed glass jar or bottle, and keep it toward the back of the fridge where the temperature is coldest and most consistent.
 
If your homemade cashew milk starts to smell sour or look grainy before the 5-day mark, toss it.

How to Store Cashew Milk So It Lasts Longer in the Fridge

If you want your cashew milk to last as long as possible in the fridge, a few simple habits make a big difference:

1. Keep It Cold and Consistent

Store cashew milk at 40°F (4°C) or below.
 
Don’t leave it sitting on the counter while you make your coffee, and always put it back in the fridge right after pouring.
 
Temperature swings speed up spoilage, so the colder and steadier you keep it, the longer cashew milk lasts in the fridge.
 

2. Seal It Tightly

Exposure to air is one of the biggest culprits behind spoiled cashew milk.
 
Keep the carton tightly closed, or transfer leftovers to an airtight container.
 
That simple step helps cashew milk stay fresh in the fridge longer than a loosely folded carton ever will.
 

3. Store It in the Back, Not the Door

The fridge door is the warmest spot because it gets opened all day long.
 
Keep cashew milk on a shelf toward the back of the fridge instead.
 
That spot holds the coldest, most consistent temperature, which helps your cashew milk last longer in the fridge.
 

4. Don’t Leave It Out Too Long

Cashew milk shouldn’t sit at room temperature for more than 2 hours.
 
So if you poured a glass and forgot about it, don’t pour it back into the carton.
 
Bacteria grow quickly at room temp, and once they’re in the carton, the whole batch spoils faster.

How to Tell If Cashew Milk Has Gone Bad

Even when you know how long cashew milk lasts in the fridge, it’s smart to double-check before drinking it:

1. Smell It First

Fresh cashew milk has a mild, slightly nutty smell.
 
If it smells sour, funky, or just off, it’s time to let it go.
 

2. Look for Separation and Chunks

Some separation is normal, just shake the carton.
 
But if cashew milk looks clumpy or has visible chunks that won’t shake out, it’s spoiled.
 

3. Taste a Tiny Sip

If the smell and look are fine, take a small sip.
 
If it tastes sour or bitter, that’s your sign the cashew milk has gone bad and should be poured out.

So, How Long Does Cashew Milk Last in the Fridge?

Cashew milk lasts in the fridge for about 7 to 10 days after opening, 3 to 5 days if it’s homemade, and until the expiration date if it’s unopened.
 
Store-bought opened cashew milk is good for about a week, homemade cashew milk is good for about 3 to 5 days, and unopened cartons last until their printed date.
 
Keep it cold, seal it tight, and always check the smell and texture before drinking.
