The invention belongs to the technical field of
wine brewing, and particularly relates to an innovative functional
yeast making method for
brewing, which comprises the following steps: mixing glutinous
sorghum, wheat, water and beautiful
millettia root in the form of extract or
powder, pretreating the beautiful
millettia root, and extracting active ingredients of
polysaccharide and
flavonoid compounds in the beautiful
millettia root so as to facilitate subsequent mixing; mixing the raw materials according to a ratio, ensuring uniform distribution, gradually raising the
internal temperature of the raw materials, entering a temperature and acid raising period, controlling the accumulation thickness, and ensuring uniform distribution of heat and
moisture; in the stacking process,
yeast is regularly turned over, heat and
moisture are uniformly dispersed, local overheating or overwetting is avoided, excessive
moisture and
carbon dioxide are discharged through
yeast turning and ventilation, mildewing is prevented, the yeast turning frequency and the ventilation quantity are adjusted according to temperature changes in the
fermentation process, the temperature is maintained within a suitable range, and the
yeast fermentation method has the advantages that various functional components are integrated, and the
fermentation efficiency is improved. The functionality and safety of the yeast for making hard liquor are improved, and the increasing health requirements of consumers are met.
