This blog post aims to provide a comprehensive guide on the shelf life, spoilage signs, and proper storage of kefir, empowering you to make informed decisions about its consumption.
Shelf Life of Kefir
The shelf life of kefir primarily depends on the following factors:
- Type of Kefir: Plain kefir generally has a shorter shelf life (7-10 days) compared to flavored kefir (14-21 days).
- Storage Conditions: Kefir stored in the refrigerator at 40°F (4°C) or below has an extended shelf life.

Signs of Kefir Spoilage
It is crucial to be aware of the telltale signs that indicate kefir has gone bad:
- Mold: The presence of mold, especially white or green, on the surface or inside the kefir is a clear sign of spoilage.
- Sour Smell: Kefir should have a slightly tangy odor. However, if it develops a strong, sour, or pungent smell, it has likely spoiled.
- Gas Production: Kefir naturally contains carbon dioxide, but excessive gas production or a fizzy texture may indicate spoilage.
