Kombucha Makers Unite; Where to ask and be answered in Recipe Sharing Posted June 16, 2014 Nice tip, M! I'm waiting for my vessel and will then try to conjure a SCOBY from bottled kombucha. My water kefir is coming out sooo fizzy with zero effort. I'm on autopilot with the process--possibly easier bc it ferments in 24-48 hours depending on heat. Curious to see how the kombucha process compares.
