    You’re all wrong. Different strains of yeast are used in making vinegar. Oxygen is integral to primary fermentation in both wine and vinegar but in secondary and bottling it is minimized because oxidation negatively affects the flavor. If you end up with vinegar when you tried to make wine, it’s because yeast that produce vinegar got into your brew.

      Yeast are used to ferment sugars to alchol, acetic acid bacteria are used to convert alchol into acetic acid. Yeast and bacteria are different.

      In our experiences, it depended on the fruit we started with. Watermelon was the worst, after like 2 weeks of brewing, it would be around half vinegar.

      Elderberry came out the best, basically the same process. Granted we didn’t use proper brewers yeast though, we just used bread yeast.

      My daddy wasn’t a normal person, but we got drunk on the cheap LOL!

        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.
