    If you end up with vinegar, it’s because of the yeast. Yeast is naturally everywhere, so when you’re fermenting you can either use chemicals or heat to sterilize your mash (whatever you’re fermenting) to help make sure only the yeast you add is populating the batch. Otherwise, yeah, the natural yeasts that are already on the fruit, grains or whatever will do their own thing.

    Keep in mind there are similar flavours to vinegar that can be produced even if there’s little to no acetic acid present, like sour beers that use lactobacillus or if you boil your grains too hot for too long on a dark beer.
