Okay, so I am going to go out here on a limb and ask my question. We purchased a brewhause 15 gallon distiller a few months ago. Thus far I have not used it, but am looking to very soon.

I guess my question based out of curiosity is this: What did people use before there were things like commercial yeast available? Obviously there is natural born yeast cultures in the air. I capture these wild yeasts to make my own sourdough culture leaving me non-dependent on the commercial products. Has anyone fermented outside for their brew OR used sourdough culture?

Maybe this is something to play around with in the future once I have learned it using commercial means?

Let me know your thoughts!
