Perfect Kombucha Perfect Kombucha For a 16 oz. bottle of kombucha: • 12 oz. fermented kombucha • The Perfect Purée flavor of choice: 1-2 tbsp. Concentrate, thawed, or 2-4 tbsp. Purée, or 2-4 tbsp. Blend, Recommendation: 1. Combine kombucha and The Perfect Purée in a 16 oz. swing-top bottle. One should adjust amounts to their own preferences. The sourness of the Kombucha is something to consider. If your fermentation is shorter, then the recommendations above should be a good start. If you tend to ferment for a long period to get an extra sour flavor, we recommend using more Perfect Purée to balance the flavor. After adding the Purée, Concentrate, or Blend, the flavored kombucha can be served as is or further fermented for a few days.
