How to Tell If Kombucha is Bad

The appearance, smell, and taste of kombucha can change as the drink ferments. If the smell or taste changes, it’s probably wrong. If it’s still odorless when placed in a glass, it may be okay to re-use it. However, if you notice mold or bacteria, throw it away. The good news is that kombucha can be fermented again. Store-bought kombucha may be better than homemade if you’re unsure.

Store-bought kombucha will likely contain added preservatives and processing to extend its shelf life. Make sure to read the guide provided with your kombucha and label the bottle correctly.
