What You Need to Know
During fermentation, malt enzymes hydrolyze starches into sugars, which are then converted by Saccharomyces cerevisiae into ethanol and by Lactobacillus spp. into lactic acid. The resulting sweet‑sour profile and low alcohol content are achieved when temperature, pH, and time are tightly controlled.
The Science
Primary Reaction
starch hydrolysis → sugar fermentation → ethanol + lactic acid
