I am on my third batch of Kombucha. The first two have turned out great, taste good and lots of fizz on second fermentation. The only problem I am encountering I think, is that the new scoby are very thin. The one on this brew from 7 days is just thinner than either of the other two, even though they also were really thin. I don't have ph strips, I intend to buy some tomorrow but I've had no mold, the tea tastes and goods good, but I'm worried that something is up.
