"How does one "discover" beer? Wine I can see. Grape juice, sits in storage till it ferments and viola, you've got wine. Beer, on the other hand, requires a scientific approach to brewing ingredients, cooking, fermenting, etc. One does not accidentally come upon beer, it must be planned and researched........."
I always thought making wine and mead was much more complicated. I've made beer for years but when I read a book on wine making I thought it was pretty fussy.
Someone cooked the barley and then let it sit in the pot.
