How Long Does Buttermilk Last?

Buttermilk is a popular ingredient in many recipes, from fluffy pancakes to tangy salad dressings. However, if you don’t use it often, you might be wondering how long it can be stored in your refrigerator before it goes bad.

The shelf life of buttermilk depends on several factors, such as the type of packaging, storage conditions, and whether it has been opened or not.


Unopened buttermilk can typically last for about two to three weeks in the refrigerator. However, once you open the container, you should use it within one week to ensure its freshness and quality.

It’s important to note that the taste and texture of buttermilk may change over time, especially if it has been stored for too long. Therefore, it’s always a good idea to check for any signs of spoilage, such as a sour smell or visible mold, before using it in your recipes.

If you find yourself with leftover buttermilk and don’t want it to go to waste, you can freeze it for future use. Just remember to pour the buttermilk into an airtight container, leaving some space for expansion, and label it with the date. Frozen buttermilk can last for up to three months in the freezer.
