Beer fermentation is the biological conversion of fermentable sugars into ethanol and CO₂ by yeast, producing the beverage’s alcohol content and carbonation.
Origin: Sumerian (~4000 BC) — Mesopotamia
See full technique reference →During fermentation, yeast metabolizes glucose via glycolysis to pyruvate, which is decarboxylated to acetaldehyde and then reduced to ethanol by alcohol dehydrogenase. CO₂ is released as a by‑product, and minor compounds such as glycerol, diacetyl, and esters contribute to flavor complexity.
