Signs of Spoiled Buttermilk
Before we delve into the factors that affect buttermilk‘s shelf life, let’s identify the telltale signs of spoiled buttermilk:
- Sour Smell and Taste: Buttermilk naturally has a sour tang, but if it develops an overpowering, pungent odor or tastes excessively sour, it’s time to discard it.
- Lumps and Separation: Fresh buttermilk should be smooth and uniform. If you notice lumps or separation, it’s a sign of spoilage.
- Mold Growth: Any visible mold or discoloration on the buttermilk’s surface is a clear indication that it has gone bad.
Factors Affecting Buttermilk’s Shelf Life
The following factors play a crucial role in determining how long buttermilk will last in the fridge:
- Refrigeration Temperature: Buttermilk should be stored at a temperature of 40°F (4°C) or below. Higher temperatures can accelerate spoilage.
- Container: Store buttermilk in an airtight container to prevent air exposure, which can lead to oxidation and spoilage.
- Acidity: Buttermilk’s acidity level plays a role in its shelf life. Buttermilk with higher acidity will generally last longer than buttermilk with lower acidity.
How Long Does Buttermilk Last in the Fridge?
The shelf life of buttermilk in the fridge varies depending on the factors mentioned above. Generally, unopened buttermilk can last up to 2-3 weeks, while opened buttermilk should be consumed within 7-10 days.
Preventing Buttermilk from Going Off
To extend the shelf life of buttermilk, consider the following tips:
- Store Properly: Keep buttermilk refrigerated at all times and store it in an airtight container.
- Use Clean Utensils: When handling buttermilk, always use clean utensils to prevent contamination.
- Freeze Buttermilk: Buttermilk can be frozen for up to 3 months. Thaw it in the refrigerator before using.
Using Buttermilk That’s Gone Off
While it’s best to avoid consuming spoiled buttermilk, there are a few instances where it can be used:

- In Baking: Slightly spoiled buttermilk can be used in baking recipes that call for buttermilk, although it may impart a stronger sour flavor.
Alternatives to Buttermilk
If you don’t have buttermilk on hand, you can substitute it with the following ingredients:
- Yogurt: Plain yogurt mixed with a small amount of lemon juice or vinegar can be used as a substitute for buttermilk in most recipes.
