Thanks, time and warmth are easy fixes. By more oxygen do you mean I should cover containers with something that allows more air flow or does that go along with time?
I recently started making kombucha. Let the first couple batches sit 8 or 9 days with first fermentation and 3 or 4 days with 2nd fermentation. Tastes like alcohol after first and second fermentation. It has good fruit flavor but a strong alcohol taste, not the sour tang like store bought...
