The invention discloses a production method for multiple-grains type Baijiu. The production method comprises the following steps: mixing, by weight, 30-45 parts of sorghum rice, 3-8 parts of corn, 10-20 parts of wheat, 8-15 parts of buckwheat and 10-15 parts of polished round-grained rice, adding the mixture to water for immersing, then performing primary steaming and boiling, and mixing the mixture with 5-10 parts of rice husk, 2-5 parts of bran, 2-7 parts of compound fruits and 2-9 parts of common yam rhizome; performing secondary steaming and boiling after urease-producing bacteria liquid moistening material is added, adding 3-8 parts of water and taking out from a resort, cooling, add 5-8 parts of daqu, 8-12 parts of aspergillus candidus, 2-5 parts of aroma-producing yeast and uniformly stirring, performing stacking fermentation after a urease-producing bacteria liquid is added, and fermenting in a pool to obtain fermented grains materials; and adding activated carbon after distillation and performing adsorption, storing after freezing and filtration, and preparing the multiple-grains type Baijiu by blending. The production method for the multiple-grains type Baijiu has the advantages of simple process, high production efficiency and high liquor yield; and the obtained Baijiu is clear and transparent, is pure in taste, is high in quality, and is stable.
