What You Need to Know
The process began with the enzymatic hydrolysis of starches by amylases from malted barley, producing fermentable sugars. Spontaneous microbial activity—primarily Saccharomyces yeasts and lactic acid bacteria—converted these sugars into ethanol, CO₂, and lactic acid, while herbs added for flavor also provided antimicrobial protection.
The Science
Primary Reaction
Starch hydrolysis → fermentable sugars → alcoholic fermentation
