What You Need to Know
The process begins with germination of maize kernels, activating endogenous α‑amylase that hydrolyzes starch into glucose and maltose. These sugars are subsequently converted by Saccharomyces yeasts into ethanol and by lactic acid bacteria into lactic acid, producing a mildly alcoholic, slightly sour drink. Temperature, pH, and amylase activity must be carefully controlled to prevent spoilage and ensure consistent flavor.
