No. One of the cool things about kombucha is that the yeast and bacteria work in symbiosis, so as the yeast continue to produce ethanol, the bacteria continue to convert that ethanol into acid. It’s a constant cycle. So the alcohol content in kombucha is self-limiting. Unlike kombucha, beer and wine are fermenting often with a purpose to drive alcohol content, so efforts in those brews usually involve removing the self-limiting components of fermentation. That being said, because real kombucha is naturally fermented and not pasteurized to kill the beneficial yeast and bacteria, the trace amount of alcohol in kombucha varies from brew to brew.
