Quick Answer
Add flavorings to fermented kombucha after it has reached the desired level of carbonation and tanginess, usually 7-10 days after the initial fermentation period. This allows you to preserve the beneficial bacteria and acids that developed during the fermentation process. Avoid adding flavorings too early, as they can be overwhelmed by the strong flavors of the SCOBY.
Choosing the Right Flavorings
When selecting flavorings for your kombucha, consider using herbs, spices, and fruits that are naturally antimicrobial and complementary to the SCOBY’s beneficial bacteria. Some examples include ginger, lemongrass, and rose hips. A general rule of thumb is to add 1-2 cups of flavorings per gallon of kombucha, adjusting to taste.
Flavoring Techniques
To extract the flavors and oils from herbs and spices, try steeping them in hot water for 5-10 minutes, then mixing the resulting liquid into the kombucha. For fruits, simply slice or chop them and add them to the kombucha, allowing the flavors to infuse over the next 1-3 days. Avoid using artificial flavorings or preservatives, as they can harm the beneficial bacteria and compromise the fermentation process.
Secondary Fermentation and Storage
After adding flavorings, allow the kombucha to undergo a secondary fermentation period of 1-3 days, which will allow the flavors to mature and the carbonation to develop. Once the secondary fermentation is complete, transfer the flavored kombucha to glass bottles with tight-fitting lids and store them in the refrigerator to slow down fermentation. This will help preserve the flavors and prevent over-carbonation.
