The invention belongs to the technical field of sweet
wine preparation, and particularly relates to a process preparation method of a sweet
wine formula, which comprises the following steps: S1, uniformly mixing clean
sorghum, wheat and corn according to a formula ratio, putting into a steamer with
steam pressure of 0.05-0.1 MPa, cooking for 60-90 minutes to ensure that the raw materials are well-done, and controlling the temperature to 38 DEG C after cooking. Fresh raw materials are selected at a
raw material end, and storage conditions are accurately controlled, so that the quality of the raw materials is guaranteed. And the parameters of the
fermentation link and each flow, such as temperature,
humidity and distiller's
yeast addition amount, are accurately regulated and controlled, so that the
fermentation stability and effect are greatly improved. The water strictly meets high standards, and interference of impurities on the quality of the sweet
wine is reduced. In addition, through strict disinfection and fine
filtration in the whole process, infectious microbe
pollution is effectively prevented. The finally prepared sweet wine is unique in
flavor, mellow in taste, stable in quality and clear brown liquid, and the requirements of consumers for high-quality sweet wine are greatly met.
