John Asked a Question

Nov 5

Is it better to add sweat tea to store bought kombucha, or to wait for the kombucha to grow a pellicle? Some add sweat tea to store bought kombucha and that becomes a full batch after a few weeks, with a pellicle and all. Others just put the store bought kombucha in a mason jar and cover it until it grows the pellicle, and then use that whole thing as the starter and add sweat tea to it. Does it matter which way you go? Is one method better than the other?
