PRACTICAL WALKTHROUGH · PARAMETERS · COMMON MISTAKES
Early Japanese sake was brewed in porous earthenware jars, allowing simultaneous saccharification and fermentation of steamed rice.
Origin: Japanese (Early Edo period) — Japan
See full technique reference →The process begins with koji mold (Aspergillus oryzae) converting rice starch into glucose at ~30 °C, followed by alcoholic fermentation of the glucose by Saccharomyces cerevisiae at 12‑15 °C. The porous clay permits controlled micro‑oxygenation and pH buffering, which stabilises enzymatic activity and yeast vitality.
Primary Reaction
Starch → Glucose (koji enzymes) → Ethanol (yeast fermentation)
