The fermentation process is where the magic happens, and microorganisms like bacteria and yeast come into play. They feed on the sugars in the grains, converting them into ethanol and carbon dioxide. It's like a little party in the fermentation tank, with the microorganisms doing the hard work of turning grains into a useful liquid.
After fermentation, the ethanol is distilled to produce a high-proof spirit. This is where the "distilled" part of white distilled vinegar comes from – the liquid is heated and condensed to concentrate the ethanol and remove impurities. It's similar to when you distill water to make it purer, but in this case, you're creating a strong spirit that will become vinegar.
