Fermented grain mash brewing is the process of converting starches to sugars and fermenting them into beer.
Origin: Mesopotamians, Egyptians, Europeans, Asians (Ancient (~4000 BC) to present) — Mesopotamia, Egypt, Europe, Asia
See full technique reference →During mashing, alpha‑amylase and beta‑amylase hydrolyse starches to maltose, maltotriose and glucose. Yeast then ferments these sugars to ethanol and CO₂, lowering the pH from ~5.5 to ~4.0. Proper temperature control optimises enzyme activity, yeast health, and flavour development.
Primary Reaction
Starch hydrolysis to fermentable sugars followed by yeast fermentation of sugars to ethanol and CO₂
