Our neighbor Rindon brought over frozen pureed blackberries and raspberries that he strained to removed the seeds. We used this to flavor the large batch 1/3 cup of blackberry (or raspberry) plus a tablespoon of sugar. We made 8 bottles of raspberry and 7 bottles of blackberry.
We pulled the raspberry and blackberry after two days. Was not explosive, the raspberry had enough fizz and was delicious, however, the blackberry was flat but tasted really excellent.
The medium batch was also strong so we used 1/2 tablespoon to each bottle. We made 8 bottles.
The large batch tasted just right and was very good. We took the large batch and added 1/3 cup pureed raspberries and 1 Tbspn of sugar. This is the first time we are using frozen raspberries. We made 14 bottles.
The medium batch was strong and vinegary so we used 1/2 Tbspn of sugar and we made 8 bottles.
The large batch made 13 bottles of lemon-blueberry. We pureed 2 pounds of frozen blueberry and added the juice of one and a half lemons. we used 1/3 cup of the lemon-blueberry and 1 Tablespoon of sugar.
We pulled at 5 days which was a mistake and it exploded on the ceiling. Blueberry is like strawberry and needs to be pulled 2-3 days. It tasted very good though and the lemon blueberry was delicious.
We used part of the large batch and medium batch to make 4 bottles of ginger kombucha. 1 teaspoon of grated ginger with 1/2 tablespoon sugar. We pulled this after 7 days, we could have used 1 tablespoon of sugar or pulled a bit sooner as it was slightly vinegary.
The remaining medium batch we used 1/2 tablespoon of sugar making 6 bottles.
The large batch tasted like strong sweet tea with little fermentation. We made 9 bottles of pineapple (from flash frozen pineapples) with 1/3 cup of pineapple puree and added 1/2 tablespoon of sugar. We also tried frozen mangoes pureed them and made 5 bottles with 1/3 cup puree and 1/2 tablespoon of sugar.
The medium batch was strong and we added 1/2 tablespoon sugar to make 8 bottles of plain.
