I’ve been making Kombucha for about a decade and have a pretty reliable system for making great kombucha at home.
It’s not for sale commercially but I will come and teach a class for you.
The picture below is of a dozen 2nd fermentation bottles with a variety of experimental flavors.
The picture below is of 8 SCOBYs in jars I sold at one of my classes. Now I think I’ll give them away in strong bags.
Until have a better way, just contact me through email or facebook to talk about a class.
