Chocolate milk is not only a kid favorite, but it’s also gained popularity as a post-workout recovery drink for adults. No matter how you plan to use chocolate milk, you should know when it goes bad!
Chocolate milk goes bad around 7-10 days past its best-by date if it’s refrigerated and sealed, and several weeks past its best-by date if it’s shelf-stable. Once opened, aim to use chocolate milk within a week for the best flavor and freshness. (It can also be frozen for up to three months.)
We’ll explain the difference between perishable and shelf-stable chocolate milk and offer specific storage guidelines for many different scenarios!
Types of chocolate milk
There are many types of milk, which means there are many options for chocolate milk! When you think of chocolate milk, your mind probably goes to chocolate-flavored “regular” cow’s milk. This type of milk comes in different fat percentages like regular milk, from nonfat to whole milk.
Non-dairy milk alternatives can also come in chocolate flavors, like chocolate almond milk.
For this article, we’ll be referring to cow’s milk-based chocolate milk of all fat contents.
What is the shelf life of chocolate milk?
Chocolate milk has at least as long of a shelf life as unflavored cow’s milk, if not slightly longer. Why? We’ll get a little science-y to explain.
The added sugar in chocolate milk increases the overall sugar content, which can cause bacteria to lose water through the process called osmosis, and without enough water, the bacteria can’t grow or multiply!
The shelf life of chocolate milk depends on whether it’s shelf-stable (ultra-high temperature milk) or perishable/refrigerated.
Shelf-stable
For shelf-stable chocolate milk stored in aseptic packaging, the shelf life is generally several months when stored at room temperature and in normal humidity. The cartons will have a printed best-by date, and the shelf-stable chocolate milk is usually good for several weeks past that date if they’ve been stored properly.
Once opened, shelf-stable chocolate milk should be used within seven days, or whatever is printed on the package.
Refrigerated
If you bought the chocolate milk from the refrigerated section, that means it’s perishable and needs to be stored in the refrigerator at all times.
Perishable chocolate milk is generally good for around 7-10 days past its best-by date if it’s been sealed (but always check for signs of spoilage first). If you open it past its best-by date, aim to use it within a couple of days since it’ll likely lose its freshness more quickly.
Once opened before the best-by date, aim to use the chocolate milk within a week for optimal flavor.
Chocolate milk shelf life summary
* If you choose to freeze chocolate milk, make sure some of the liquid is removed from the container (if it’s full) to allow room for expansion during the freezing process.
Refrigerator – SEALED | Refrigerator – OPEN | Room temperature | Freezer | |
Perishable chocolate milk (refrigerated) | 7-10 days past best-by date | 7 days; around 2-3 days if opened past best-by date | N/A | Up to 3 months* |
Shelf-stable/UHT chocolate milk | Likely a couple of months past the best-by date | 7 days, or whatever is printed on the package | A few weeks past the best-by date | Up to 3 months* |
How long does chocolate milk go bad after opening?
For ideal freshness, try to use chocolate milk within a week after you open it. It’ll likely last longer than that, but the United States Department of Agriculture (USDA) recommends using it within seven days after opening.
Can you use chocolate milk after its expiration date?
Chocolate milk is likely fine to use a few days after its expiration date if it’s been sealed. If it’s been open for a while, it’s better to toss it.
Shelf-stable chocolate milk is generally fine to use even longer past its expiration date (several weeks or more) since it’s treated at higher temperatures to prevent bacterial growth. If it shows signs of spoiling, though, then don’t risk it.
How to tell if chocolate milk went bad
Consistency: If there are large clumps or grittiness to chocolate milk even after you’ve shaken it, it might be bad.
Smell: Chocolate milk will take on a sour smell like regular milk once it’s past its prime, so give it a sniff to assess if it’s gone bad.
Taste: Chocolate milk should taste delicious and chocolatey. If it tastes bad, it’s a sign it’s spoiled.
What’s the danger in using chocolate milk after it’s gone bad?
Drinking a small amount of chocolate milk after it’s gone bad isn’t dangerous. If you happen to drink a large amount of spoiled chocolate milk, you might get an upset stomach. If you have any severe signs of food poisoning from bacterial growth, reach out to your healthcare provider for advice!
Best storage practices for chocolate milk
- Always keep perishable chocolate milk refrigerated, ideally between 33-38 degrees Fahrenheit. Shelf-stable chocolate milk should also be kept in these conditions once it’s opened.
- Keep containers of opened chocolate tightly sealed at all times.
- Shake chocolate milk before using it, which helps redistribute the chocolate flavoring and fat within the milk.
- Store shelf-stable chocolate milk at room temperature and normal humidity. Excessive heat (above 95 degrees Fahrenheit) and humidity can reduce its shelf life.
FAQs:
Is chocolate milk spoiled milk?
Don’t worry, brown milk isn’t bad milk – it’s just brown from the chocolate flavoring! If your milk is brown and it’s not chocolate-flavored, that’s a problem, though…
How long can chocolate milk go unrefrigerated?
Chocolate milk shouldn’t be out of the fridge longer than two hours. The exception is shelf-stable chocolate milk, which is good for many months when sealed at room temperature.
