Now comes the tricky part... How do we get yeast? The homebrew shop, with its neat little vials of beer yeast around the world, is perhaps a smoldering ruin. Seems shaky to me, but the tried and true i.e. 10,000 year old method is simply to toss wild fruit skins into the wort. Grapes, preferably. Maybe i can find some in some canyon. More likely apples.
