In the technology of Fen-flavor liquor, the biggest feature of low-temperature koji-making is the high yield of liquor, and there are many kinds of specific raw materials, such as sorghum, corn, wheat and barley. The greater the wine production, the higher the contents of ethyl acetate and ethyl lactate. Therefore, the fragrance of Fen-flavor liquor is elegant and pure.
There is a core in the "12987 soul craft" of high-quality maotai-flavor liquor, which is "three highs and three lengths", and among them, it is high-temperature koji making. Of course, in the process of koji making, koji blanks can be divided by temperature, and there are also medium-high temperature koji making, medium temperature koji making and low temperature koji making. For example, the koji-making temperature of Moutai is generally above 60 degrees, and the high-quality Daqu of Maotai-flavor liquor is made at high temperature.
