                                Kombucha fermentation relies on sugar as a critical fuel source for the SCOBY (Symbiotic Culture of Bacteria and Yeast). The initial sweetened tea might contain a significant amount of sugar, but the SCOBY consumes most of it during the fermentation process. The type of sweetener used is central to both the fermentation's success and the final flavor profile of the brew.
