What You Need to Know
During fermentation, lactic acid bacteria convert fermentable sugars in the grits into lactic acid, lowering the pH and inhibiting spoilage organisms. Yeasts concurrently produce small amounts of ethanol, contributing to the characteristic aroma and mild alcohol content. The combined acidification and ethanol production preserve the porridge and create a tangy, slightly sweet flavor profile.
