Commercial VS Home Brew?
Home-brewed kombucha typically has more alcohol than the store bought varieties. For a while the store bought kombucha had alcohol levels higher than the legal limit. So the FDA/CFIA made it compulsory for commercial brewers to pasturize their yeast strains. It is unclear on if the pasturization process disrupts the beneficial bacteria. Since home-brewed kombucha is unpasturized there are possible health benefits over store bought kombucha. When more studies are done we will know if the pasturization process eliminates the beneficial components of store bought strains.

Yikes! What The Heck Is That!?
Let me introduce you to the star of the kombucha making process. This is S.C.O.B.Y. which stands for Symbiotic Culture of Bacteria and Yeast. The combination of bacteria and yeast operate together to transform the sugar and tea into the delicious drink known as kombucha tea. Your S.C.O.B.Y. is continously growing and shaping itself to your vessel. You can use a dehydrated S.C.O.B.Y. but it can takes numerous weeks to rehydrate. I found you can grow one quicker from using raw kombucha.
