How Long Does Buttermilk Last?
The answer to this question depends on the type of buttermilk you use and the temperature at which it was made. If your buttermilk is not fresh, then its shelf life will be short. Fresh milk contains live bacteria that break down lactose into lactic acid. Lactose is the sugar found in milk. When you add water to make buttermilk, the bacteria produce lactic acid. The lactic acid causes the milk to curdle (turn cloudy) and become less nutritious. After several days, the bacteria die off and the milk becomes rancid.
If you have stored your buttermilk properly, it may last indefinitely. However, if you store it too cold or in a closed container, the bacteria may grow and spoil the milk before it gets to you. You could even get sick from drinking spoiled milk!
However, if your buttermilk is fresh and unpasteurized (not pasteurized), then its shelf life will be much longer than that of regular dairy products.
Many dairy farmers don’t pasteurize the milk they sell from their farms because if they did, it would not be fresh for long. Without pasteurization, the shelf life of the milk is only 2 to 3 days! That’s because before pasteurization was invented in the 1800s, a few harmful bacteria were able to enter the milk and multiply quickly.
So, does buttermilk go bad?
The answer is maybe. Fresh, unopened buttermilk will keep much longer than pasteurized buttermilk that has been opened and left at room temperature.
How Long Does Unopened Buttermilk Last?
Unopened pasteurized buttermilk lasts for about 2 to 4 weeks after the pack date (this is usually printed on the carton). The pack date can be found on the side or bottom of the carton. But remember, it won’t go bad in 2 or 4 weeks; it’s still safe to drink after that time period. It just won’t taste as good!
If the buttermilk is unpasteurized (it says on the carton), then it lasts for about 2 to 3 months after this date. The taste of the buttermilk will change after this time period, but it is still safe to drink.
How to Tell If Buttermilk Is Bad?
Buttermilk is a fermented food, so it does not spoil easily. But if kept past its expiration date, it can eventually grow mold, especially if it has been opened and left at room temperature. Of course, if you see mold on the top of the buttermilk, throw it away. If it smells bad when you open the carton or if it seems strangely thick or lumpy, then don’t drink it.
Does Buttermilk Separate?

Always remember to check the use-by, best before and sell-by dates so you know how long a food is good for.
The longer you’ve had a certain item, the closer it is to its expiration date, so keep this in mind as well.
