What even is yeast? I am thinking mainly of the kind we use to make bread rise. Which I buy from the grocery store…
But, back in the day, where did people find yeast? I assume people cultivate it and grow it, much like sour dough, but someone had to find it originally, right?
And what does ir do in the wild? Especially since it is so easy to kill? (Can’t be too hot, can’t touch salt, can’t be too old…)
Note: this is purely to do with my curiosity. I have no interest in actually hunting wild yeast

‘Yeast’ refers to a bunch of different species of single-celled fungus. It exists all around the place, and if you use different things as “starters” (for instance, fruit skins) you can cultivate some interesting sour dough flavours.
The yeast you buy from the store is one particular species – *Saccharomyces cerevisiae*, aka brewer’s yeast or baker’s yeast.
