In order to explore the effect of Wickerhamomyces on production flavor compounds in Xiaoqu Baijiu, this study examined correlation between fungal communities and ester compounds. It was hypothesized that contributes aroma Xiaoqu. Enhanced fermentation methods were used validate role Baijiu brewing. Compared traditional Xiaoqu, enhanced significantly increased acidity fermented grains starch utilization rate (P<0.05). The analyzed by high-throughput sequencing technology. dominant fungi both control test groups Saccharomyces, Cyberlindnera, Rhizopus, Meyerozyma, with replacing Saccharomymycopsis group. Flavor experiments analyzed, revealing ethyl acetate content 949.94 mg/L group, while isoamyl alcohol decreased 23.62 isobutanol 34.81 mg/L. Functional prediction analysis using PICRUSt2 confirmed a higher relative abundance enzymes involved metabolism lower These findings demonstrate enhances reduces alcohols during brewing, offering theoretical foundation for enhancing quality Baijiu.
