Amouranth, the Kick streamer, is allegedly brewing beer with her vaginal yeast. It’s an obvious publicity stunt to squeeze more money from her impressionable and “thirsty” audience.
Gross-factor aside, is this even possible? Is it analogous to brewer’s yeast? Would this cause undesirable side effects or introduce undesirable compounds?
Several drinks have “store barrel in cave/shed in specific region” as a manufacturing step, specifically because of the wild yeast in the area.
But only a small number, because making people violently sick is a poor business strategy.
