I understand that vinegar is fermented wine (which is itself fermented sugar). But when I leave something like a cup of soup sit out for awhile, it begins foaming and develops a vinegar taste. This isn't food with alcohol in it (it even happens when I'm soaking a pot of beans, there's nothing but beans and water and the foaming/vinegar still happens), so:
1) What microbe (if that?) is causing the foaming,
2) Is it vinegar or something chemically related?
3) Is it safe to eat "raw"? I return any affected foods to a boil to kill off anything unsafe, and I don't mind the vinegar flavour, I just wonder if I need to be re-cooking the stuff.
Even if you can't answer #1, I'd apreciate the answer to #2. I'm mainly confused about what it is, because it tastes like vinegar but I'm told that vinegar only comes from alcohol.
Whatever that microbe is, I must have a LOT of it in my apartment's air, because I get that foaming action quickly. =p
