I am overall pleased with the purchase of this starter kit. I am a first time home brewer of Kombucha and this was very beginner friendly. The only thing I am not certain of is, during my research and being on all sorts of Kombucha blogs, I have read/learned that you need 2 cups of starter liquid per gallon. I didn't specifically measure, but I don't think the starter liquid that came with the pellicle was 2 cups, I think it was more like 1 cup, and it did say it makes a gallon, so it may be a little misleading. Fortunately, this did NOT have a negative impact on my batch. My first batch did take a little over 2 weeks to be ready for F2 (which is quite long), but I was still able to get a good batch out of it, which also helped to create future batches. I am now on my 4th batch, so needless to say, even if it wasn't a full 2 cups of starter liquid per gallon, it still worked, just took a bit longer!
