Introduction to Kombucha Troubleshooting
For more kombucha tips, check out our kombucha brewing guides.Kombucha is a fermented tea drink that has gained popularity worldwide for its potential health benefits and unique taste. However, brewing kombucha can be a delicate process, and various issues may arise, such as mold, off-taste, and carbonation problems. In this article, we will explore the common issues encountered when brewing kombucha and provide step-by-step solutions to troubleshoot them.
Equipment Needed for Troubleshooting
- Large glass jar or container with a wide mouth
- Cheesecloth or a coffee filter
- Rubber band
- Stirring spoon
- Thermometer
- pH meter (optional)
- Bottles with tight-fitting lids for secondary fermentation
Troubleshooting Mold in Kombucha
Mold is one of the most common issues when brewing kombucha. It can appear as a white, green, or black fuzzy patch on the surface of the SCOBY (Symbiotic Culture of Bacteria and Yeast) or in the liquid. To prevent mold, it’s essential to maintain a clean environment and ensure the SCOBY is healthy.
Step-by-step solution to mold:
- Discard the contaminated SCOBY and liquid.
- Clean and sanitize the equipment and workspace.
- Start a new batch with a healthy SCOBY and fresh ingredients.
Troubleshooting Off-Taste in Kombucha
An off-taste in kombucha can be caused by various factors, such as the type of tea used, the fermentation time, or contamination. To resolve the issue, try the following:
- Adjust the fermentation time: shorter or longer fermentation can affect the taste.
- Change the type of tea: some teas may produce a stronger or weaker flavor.
- Check for contamination: ensure the equipment and workspace are clean and sanitized.
Troubleshooting Carbonation in Kombucha
Carbonation is a critical aspect of kombucha, as it contributes to the drink’s characteristic fizziness. To achieve the right level of carbonation, follow these steps:
- Secondary fermentation: transfer the kombucha to bottles with tight-fitting lids and let it ferment for 1-3 days at room temperature.
- Monitor the carbonation: check the bottles regularly to avoid over-carbonation.
- Refrigerate: once the desired level of carbonation is reached, store the bottles in the refrigerator to slow down fermentation.
Pro Tips for Brewing Kombucha
- Use filtered water to prevent contamination and off-tastes.
- Maintain a consistent temperature: ideal fermentation temperature is between 68-85°F (20-30°C).
- Monitor the pH level: the ideal pH range for kombucha is between 2.5 and 3.5.

Frequently Asked Questions (FAQ)
- Q: Why is my kombucha too sour?
- A: Kombucha can become too sour if the fermentation time is too long. Try reducing the fermentation time or adding a small amount of sugar to balance the flavor.
- Q: Can I use a metal container for brewing kombucha?
- A: No, it’s not recommended to use metal containers, as they can react with the acidic nature of kombucha and contaminate the brew.
