Shelf Life Of Buttermilk
Buttermilk, whether unopened or opened, can last up to 3 months in the refrigerator. If the buttermilk is extremely thick, has a sour smell, and/or has mold on the lid or floating on top, it is bad and should not be consumed. When it comes to homemade buttermilk, as long as it is stored in an airtight container in a very cold part of the fridge, it can last up to two weeks. Buttermilk can also be frozen to prolong its shelf life, although the texture may become slightly grainy after thawing. However, it is still suitable for use in most recipes, especially cooked and baked dishes. It’s important to note that buttermilk has a longer shelf life than fresh milk due to its high lactic acid content, which inhibits the growth of harmful bacteria.
Freezing Buttermilk
Freezing buttermilk is a simple and effective way to preserve it. The texture may become slightly grainy after thawing, but it can still be used in most recipes. It’s best used in cooked and baked recipes like pancakes and biscuits, but it can even work in dressings like ranch dressing. To freeze buttermilk, make sure it is in an airtight container. Leave some space at the top for expansion during freezing. Label the container with the date and use within 3 months for the best quality. When you’re ready to use the frozen buttermilk, thaw it in the refrigerator overnight or in the microwave on the defrost setting. Give it a good stir before using to blend the texture.
Homemade Buttermilk
Homemade buttermilk can last up to 2 weeks when stored in an airtight container in the refrigerator. If buttermilk is extremely thick, coming out of the container in large lumps, and/or has a very sour smell, it is bad. There might even be some mold on the lid of the buttermilk or floating on top. Bad buttermilk is very thick and has large chunks. Guidelines from agricultural programs at various universities recommend consuming buttermilk within three weeks of the date stamped on the package. In the test kitchen, it has been found that buttermilk won’t turn truly bad (signified by mold growth) until at least three weeks after opening. As long as you store homemade buttermilk in an airtight container in a very cold part of your fridge (i.e.: not the doors, which are the warmest and most often exposed to warmer air), it can last up to two weeks. Freezing buttermilk is also a simple and effective way to preserve it, although the texture may become slightly grainy after thawing.

By following proper storage methods and regularly checking for any signs of mold or unpleasant odors, you can still utilize expired buttermilk safely.
Buttermilk Substitutes
When it comes to buttermilk substitutes, you have a few options to choose from:
1. Lemon juice: Lemon juice is a common substitute for buttermilk in recipes. Simply mix 1 tablespoon of lemon juice with 1 cup of whole milk and let it sit for 5 minutes until it curdles. This will give you a tangy flavor similar to buttermilk. 2. Sour cream: Sour cream can also be used as a substitute for buttermilk. Mix 3/4 cup of sour cream with 1/4 cup of water to achieve a similar consistency to buttermilk. This will add a creamy texture to your recipes. 3. Whole milk: In a pinch, you can use whole milk as a substitute for buttermilk. Just remember to add 1 tablespoon of lemon juice or white vinegar to 1 cup of milk and let it sit for 5 minutes. This will help to mimic the tangy flavor of buttermilk. Overall, these substitutes can be effective when you don’t have buttermilk on hand. However, they may not provide the exact same flavor and texture as using real buttermilk in your recipes.Tips For Properly Storing Buttermilk
Properly storing buttermilk is essential for extending its shelf life. To keep your buttermilk fresh for a longer time, follow these tips:
- Store buttermilk in the coldest part of the refrigerator, such as the back shelf, to maintain its quality. Avoid storing it in the refrigerator door where the temperature fluctuates frequently.
- Use an airtight container to prevent air exposure and maintain the freshness of the buttermilk.
By following these simple guidelines, you can ensure that your buttermilk stays fresh and usable for a longer period. Remember to check the expiration date on the packaging and consume it within the recommended timeframe.
What Is Buttermilk?
Buttermilk is a versatile ingredient that is commonly used in baking and cooking. It is a tangy and creamy liquid that is left behind after churning butter from cream. Buttermilk has a longer shelf life than fresh milk due to the presence of lactic acid, which acts as a natural preservative and inhibits the growth of harmful bacteria. When stored in the refrigerator, unopened buttermilk can last for up to 3 months. However, once opened, it should be used within 2 weeks to ensure freshness. If you have homemade buttermilk, it can also last for up to 2 weeks when stored in an airtight container in the coldest part of your fridge. Alternatively, you can freeze buttermilk to extend its shelf life. Although the texture may become slightly grainy after thawing, it is still suitable for use in most recipes.
Conclusion
Buttermilk has a relatively long shelf life compared to fresh milk due to its high lactic acid content, which inhibits the growth of harmful bacteria. It is recommended to consume buttermilk within three weeks of the date stamped on the package.
However, in our test kitchen, we found that buttermilk won’t turn truly bad until at least three weeks after opening. Additionally, homemade buttermilk can last up to two weeks if stored in an airtight container in the refrigerator. Freezing buttermilk is also a viable option to extend its lifespan.
Just remember to stir it up after thawing, as the texture may become slightly grainy. So, next time you’re wondering how long buttermilk lasts, you can confidently refer to these guidelines to make the most of this versatile ingredient.
