In order to screen yeast strains suitable for low-temperature brewing rice wine, this study isolated and purified and screened yeast with comfortable aroma production, excellent fermentation capacity, alcohol production capacity and ester production capacity at low temperature from rice bent, and identified the strain by morphological observation and molecular biology methods, analyzed its growth and tolerance, and applied it to low-temperature brewing rice wine. The results showed that a low temperature tolerant yeast strain XQ2-8 was isolated...
