Amazake has always been the same thing: white, thick, faintly grainy, sweet enough to taste like rice pudding. KOJI CLEAR breaks that rule on purpose.
It starts with amekoji — a koji technique developed in Akita, a region that has spent centuries perfecting fermentation. By pairing that koji with a second koji — white koji — and filtering the result, we arrive at something remarkably clear, with a naturally pale-gold tone: clean, faintly sweet, quietly complex.
Its gentle sweetness and tartness come from the glucose and citric acid that the koji produces on its own — not from added sugar.
Three ingredients. No more.
- — Akita-grown rice koji
- — Rice
- — Water
No added sugar. No preservatives. No additives.
KOJI CLEAR is planned and sold by Es Inc. It is manufactured by a partner facility in Akita.
What is koji?
— Koji is rice (or another grain) inoculated with Aspergillus oryzae, the mold at the center of Japanese fermentation. It's the starting point for miso, soy sauce, amazake — and now, KOJI CLEAR.
What is amekoji?
— A technique developed in Akita for drawing a natural, concentrated sweetness out of koji without adding sugar.
What is white koji?
— A koji strain valued for the citric acid it naturally produces — the source of KOJI CLEAR's gentle tartness.
Why is KOJI CLEAR so clear?
— Because after fermentation, the rice solids are filtered out. What's left is the flavor, without the cloudiness — a clear liquid with a naturally pale-gold tone.
