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

The easiest place (that I know of) to find yeast is on grapes. That hazy coating you see on grape skin is the yeast.
And I can attest, you can make bread with any kind of live yeast. Try making bread with brewer’s yeast used for making beer (the live yeast brewers use, not the “brewer’s yeast” dietary supplement you find in health food stores), and you’ll be so pleased with the outcome that you’ll never go back to baker’s yeast.
