First, someone has to make alcohol. I know, right? The best part of vinegar production is that it starts with a party. For white vinegar, manufacturers usually use corn or grain—they mash it up, add water, and let enzymes break down the starches into sugar. That sugary liquid is then fed to yeast, which promptly gets drunk on it and produces ethanol (a.k.a. booze).
Think of it as the yeast’s wild night out. They eat the sugar, burp out carbon dioxide, and leave behind a liquid that’s basically a weak beer or a raw vodka. This isn’t your fancy craft cocktail—it’s industrial alcohol, and it’s about to get a serious makeover.
Why Not Just Use Wine?
You might wonder, “Why don’t they just use cheap wine?” Great question! Technically, they could, and some small-batch vinegars do. But for the clear, neutral white vinegar you buy, the goal is zero flavor from the original source. They want the purest, most neutral alcohol possible so that the final vinegar doesn’t taste like corn or grain. It’s the flavor equivalent of a blank canvas.
