What ratio of juice to kombucha should I use for the second fermentation (to add flavor)?
A. Generally speaking a ratio of 20% juice and 80% kombucha works well. We’ve also had customers report good luck adding fresh fruit (peaches are a favorite) to the kombucha. But adding fruit and juice is one place you can certainly experiment to find your preferred flavors. When using fresh fruit, be sure to limit the amount of time the mixture is allowed to sit (24-48 hours).
