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

During earlier times before commercial yeast was available, people used sourdough starters. There is naturally occurring yeast in flour and if you mix flour and water and let it sit, it will ferment and “rise.”
Otherwise, breweries sold yeast as a by-product of making beer.
