What You Need to Know
During fermentation, yeasts metabolize sugars to ethanol and CO₂, while co‑existing lactic acid bacteria convert sugars to lactic acid, lowering the brine’s pH. The combined action of ethanol, CO₂, and acids creates a complex flavor profile and preserves the vegetables. Temperature and time control the balance of these reactions, preventing spoilage and ensuring safety.
The Science
