If your buttermilk has been hanging out at the back of the fridge for a while, you might not be sure if it's still good to use. Since buttermilk has a signature tangy flavor, it can be hard to tell if buttermilk has gone bad based on taste alone. Don't worry—we'll go over all the signs of spoiled buttermilk, and put your mind at ease if you accidentally eat bad buttermilk.
How Long Does Buttermilk Last?
Your buttermilk is likely expired if it’s thick or chunky, smells sour or tangy, has dark colorations or mold in it, or if it’s been at room temperature for more than two hours. Buttermilk can keep 2-3 weeks in the fridge and up to 1 week past its expiration date.

Almost all buttermilk that you buy from the store is cultured—it's skim milk with added bacteria and citric acid to give it a tangy flavor. Traditional buttermilk is the thin liquid that's leftover from making butter.Thanks
