I tasted the Kombucha I made on about August 12. It is finally losing the sweetness. I don't like mine too sweet. I'm thinking about another week. Interesting that this batch is working again. I am wondering if the problem I had using green tea and both batches molding, may be that the green tea contained mold spores? This batch made with black tea is fine. Can't wait. I'm going to try ginger!! I love GT'S Organic Raw Kombucha Gingerade.
