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?
One of the most important aspects of these brewers yeasts versus regular bakers yeasts or wild yeasts (like a sourdough starter) is that they can thrive in higher alcohol environments, allowing them to convert more sugar into alcohol…
And it was this aspect that I learned about just a few days prior that led me to question the whole thing. For the purposes of making what average people would consider beer, it seemed like you couldn’t just swap in whatever you wanted.
You definitely can use wild yeasts to make alcohol. It probably won’t work as well or as consistently, but I’m sure you can make some good stuff just by letting things ferment naturally. I bake a lot of sourdough and it’s very fiddly compared to commercial yeasts. You also technically can use bakers yeast for brewing, but I think it’s not ideal for various reasons, like the flavour can be different and I think it doesn’t clump together as much so it’s harder to remove.
