What You Need to Know
The process begins with gelatinization of malted barley starches at ~65 °C, releasing β‑glucans and fermentable sugars. Wild yeasts and lactic‑acid bacteria then convert sugars to ethanol and lactic acid, lowering pH to ~4.2. Honey phenolics and essential oils from herbs such as pennyroyal or thyme add antimicrobial activity and aromatic complexity.
