The invention relates to the technical field of white spirit brewing, and particularly discloses a brewing method of red yeast rice white spirit. The brewing method is characterized in that sorghum, rice, millet, corn, wheat and pea are used as raw grains, red yeast rice, white yeast rice, dry yeast, vinasse and steamed bran husk are used as auxiliary materials, and the product is obtained throughraw grain crushing, vinasse adding, steamed bran husk adding with water for moistening and stewing, stewing, red yeast rice, white yeast rice and dry yeast adding into a cellar for fermentation, discharging out of the cellar for distillation and ageing. Wherein the red yeast rice accounts for 12-18% of the total weight of the unprocessed grain, the white yeast rice accounts for 5-10% of the totalweight of the unprocessed grain, and the dry yeast accounts for 0.5-2% of the total weight of the unprocessed grain; wherein the fermentation temperature is kept at 20-25 DEG C, and the fermentationtime is 28-32 days. The Baijiu and Baiqu compound use mode improves the liquor yield of Baijiu, solves the problem of the liquor yield rate in the traditional process, improves the total acid and total ester, forms the aroma components of white wine, improves the quality of liquor and ensures the style of liquor.
