Answer 1

Think of it this way, the alcohol produced via fermentation is the byproduct of yeast metabolism, so think of the alcohol as the yeast’s poo. The byproduct of humans eating food is poop, the byproduct of yeast eating sugar is alcohol. The bacteria used to ferment cabbage is a different species and doesn’t “poop” alcohol it poops something else.
