What You Need to Know
The high pentosan content and lower gluten strength of ancient grains demand greater hydration and longer autolysis to develop a functional gluten network. Controlled fermentation temperatures (24‑28 °C) and acidity (pH 3.8‑4.2) optimize starch conversion to fermentable sugars and lactic‑acid production, while preventing excessive acetic‑acid buildup that weakens gluten.
The Science
Primary Reaction
Starch → maltose → lactic acid + acetic acid + CO₂
