Sake Yeast & Koji

Sake Yeast and Koji for Home Sake Brewing

Sake yeast and koji are core ingredients in sake brewing. Koji turns steamed rice into an enzyme-rich ingredient that can convert rice starch into fermentable sugar, while sake yeast carries out alcoholic fermentation.

Sake brewing is more process-sensitive than most simple fermentations. Rice washing, soaking, steaming, koji handling, temperature control, staged additions, yeast health, sanitation, and recipe timing all matter. Use this collection to find the yeast and koji ingredients that support a complete sake recipe.

How these ingredients fit the process

  • Koji starter: use Koji Kin to inoculate properly prepared rice for koji production.
  • Sake yeast: choose yeast according to the recipe, fermentation temperature, and flavor target.
  • Rice planning: use polished sake rice where the recipe calls for it.
  • Recipe support: follow a complete sake process instead of treating koji and yeast as direct substitutes for ordinary beer yeast.

Start with Koji Kin sake starter, pair it with Calrose 70% polished sake rice, and browse sake making ingredients or the full sake making collection.
