Many people argue that you cannot use raw honey in the fermentation process because raw honey is known to have anti-bacterial agents. Their concern is that it would kill the mother culture such as kombucha.
Honey is anti-microbial in nature, but it kills microbes primarily by suffocation, so mixed with water, its antimicrobial properties are somewhat diminished and it becomes a happy home and food source for airborne yeasts and organisms to feast on and produce a traditional fermented product.
So, find yourself a source for high-quality local raw honey and enjoy your fermentation experiments.
