Although,about the method, it is often misconceived that "No rice malt is necessary" or "Single fermentation is done, not multiple parallel fermentation," the multiple parallel fermentation is actually done, which requires saccharification with rice malt (the rice malt over 3% of the amount of the original rice is required).
よく、「麹が不要」「並行複発酵ではなく単発酵」と誤解されているが、実際は麹による糖化が必要な並行複発酵(麹歩合が原料米の3%以上必要とされる)。
