The sixth yeast is the oldest seishu yeast among the yeasts which are still used today and the long-term fermentation kept at low temperatures became the prototype of ginjoshu (high-quality sake brewed at low temperatures from rice grains milled to 60 percent weight or less) later. 第6号酵母は現在も使われている酵母としては最も古い清酒酵母であり、また低温長期醗酵はのちの吟醸酒の誕生の原型となった。 |
