Buttermilk is a versatile dairy product that adds a tangy flavor to various recipes. However, like any other perishable food item, buttermilk has a limited shelf life. Understanding how long buttermilk lasts in the refrigerator is crucial to ensure its freshness and prevent foodborne illnesses.
How Long Does Buttermilk Last in the Refrigerator?
Unopened buttermilk can typically last for up to two to three weeks in the refrigerator. The airtight packaging helps preserve its freshness.
Once opened, buttermilk’s shelf life is significantly shorter. It can last for five to seven days in the refrigerator, provided it is properly stored.
Signs of Spoiled Buttermilk
Spoiled buttermilk exhibits several telltale signs:
- Sour smell: Buttermilk has a slightly sour aroma, but if it becomes overly pungent or rancid, it has likely spoiled.

- Separation: Buttermilk may separate into a watery liquid and a thick curd. While this is not necessarily a sign of spoilage, it may indicate that the buttermilk is nearing the end of its shelf life.
- Curdling: Buttermilk should have a smooth consistency. If it becomes curdled or lumpy, it has likely spoiled.
