Are there any signs that kombucha has gone bad after bottling (in storage)?

Question

Are there signs that bottled kombucha has gone bad? Learn how to tell if your stored kombucha has spoiled, beyond just becoming more vinegary over time.

Answer 1

Yes, signs that kombucha has gone bad after bottling include mold growth, a vinegary or putrid smell, a significant change in taste, or excessive pressure buildup in the bottle. If any of these are present, it's best to discard the kombucha.

Detailed Explanation:

Kombucha, being a fermented beverage, can sometimes go bad even after bottling. Here's a breakdown of what to look for:

1. Mold: This is the most obvious sign. Mold can appear in various colors (green, black, blue) and textures. If you see any mold, discard the entire batch. It's different from the normal SCOBY strands that might form.

2. Smell: A healthy kombucha smell is typically tart and slightly vinegary. If it smells putrid, cheesy, or otherwise off-putting, it's likely spoiled.

3. Taste: A drastic change in taste, especially if it becomes overwhelmingly sour or bitter, can indicate spoilage. While kombucha naturally becomes more acidic over time, an extreme change is a red flag.

4. Excessive Pressure: Kombucha is carbonated, but excessive pressure buildup in the bottle can be dangerous. If the bottle feels extremely hard or shows signs of bulging, it could explode. Handle with caution and release pressure slowly, or discard it carefully.

5. Sediment: Some sediment is normal in kombucha, but excessive or unusual sediment could be a sign of unwanted microbial activity.

Pro Tip:

Always use high-quality bottles designed for carbonated beverages when bottling kombucha. This helps prevent explosions due to pressure buildup. Also, store your bottled kombucha in the refrigerator to slow down fermentation and prevent spoilage.
