Buttermilk, a cherished ingredient in culinary creations, adds a tangy touch to pancakes, waffles, and baked goods. But how long does this dairy delight last in the fridge? Understanding the shelf life of buttermilk is crucial to prevent spoilage and ensure its safe consumption. In this comprehensive guide, we’ll delve into the intricacies of buttermilk’s longevity and answer the question: “Does buttermilk go bad in the fridge?”
Signs of Spoiled Buttermilk
Buttermilk, like any dairy product, can deteriorate over time. Here are telltale signs that your buttermilk has gone bad:
- Sour Smell and Taste: Buttermilk naturally has a slightly sour aroma. However, if the smell becomes excessively pungent or unpleasant, it’s a sign of spoilage. Additionally, sour or bitter taste indicates bacterial growth.
- Lumps or Separation: Fresh buttermilk should be smooth and uniform. If you notice lumps or separation, it’s a sign that the buttermilk has curdled and is no longer safe to consume.
- Mold Growth: Mold is a clear indication of spoilage. Any traces of mold on the surface or inside the buttermilk should be discarded immediately.
- Discoloration: Fresh buttermilk has a pale white or slightly yellowish color. If it turns green, pink, or any other abnormal color, it’s best to discard it.
Shelf Life of Buttermilk in the Fridge
The shelf life of buttermilk in the fridge depends on several factors, including:
- Type of Buttermilk: Homemade buttermilk, made from fresh milk, has a shorter shelf life (up to 2 weeks) compared to store-bought buttermilk, which contains stabilizers and preservatives.
- Storage Conditions: Buttermilk should always be stored in an airtight container in the coldest part of the refrigerator (typically the back or bottom shelf).
- Opening the Container: Once the container is opened, buttermilk is exposed to air and bacteria, which can accelerate spoilage.
How to Store Buttermilk Properly
To extend the shelf life of buttermilk, follow these storage tips:
- Refrigerate Immediately: After purchasing or making buttermilk, refrigerate it immediately.
- Use an Airtight Container: Transfer buttermilk to an airtight container to prevent oxidation and contamination.
- Avoid Freezing: Buttermilk should not be frozen as it can alter its texture and flavor.
Can You Use Expired Buttermilk?
While it’s not recommended to consume buttermilk beyond its expiration date, there are some exceptions:
- Within a Few Days: If buttermilk is only a few days past its expiration date and shows no signs of spoilage, it may still be usable for baking purposes.
- Baking Only: Expired buttermilk should only be used in baked goods, where its sourness can enhance flavor. Avoid using it in drinks or as a topping.
Health Risks of Consuming Spoiled Buttermilk
Consuming spoiled buttermilk can lead to foodborne illnesses, such as:
- Stomach Upset: Nausea, vomiting, and diarrhea are common symptoms.
- Food Poisoning: In severe cases, spoiled buttermilk can cause food poisoning, leading to fever, chills, and muscle aches.
- Allergic Reactions: Some individuals may experience allergic reactions to spoiled buttermilk.

If you’re out of buttermilk or concerned about its shelf life, there are several substitutes you can use:
- Yogurt: Plain yogurt can be substituted for buttermilk in most recipes.
