I'm only learning as I go but we're loving Kombucha at home. At least once a week we split a bottle. :) I understand that you can grow your own Kombucha, but I'm going with the lab tested and monitored batches versus "home grown" as "results may vary."
Digestively speaking, great stuff. Really cleans you out. LOL
