Hongxin (HX) is an indispensable Daqu in the production of light-flavor Baijiu (LFB). However, classification method HX highly subjective, and functional differences microorganisms different grades are still unclear. In this study, metagenomics physiochemical analysis were used to compare three (top, first, second) clarify their brewing functions LFB. The results showed that a total 1556 genera 5367 species detected all samples. Bacteria fungi main HX, relative abundance bacteria above 4.5:1. Kroppenstedtia (11.43%), Leuconostoc (10.52%), Fructilactobacillus (9.00%) top HX. Although microbial community composition similar, each has specific structure macrogene characteristics, indicating they have functions. dominant top-grade first-grade mainly positively correlated with energy metabolism lipid metabolism, while second-grade carbohydrate amino acid metabolism. This study revealed fermentation effects LFB provided suggestions for scientific quality control
