Objective To screen the tea cultivars with better productive character of "Huhong" Congou black tea. Methods Three tea varieties including Bixiangzao, Huangjincha, Zhuyeqi were selected as materials and black bar tea was made by traditional black tea processing technology. Through sensory evaluation and dynamic analysis of quality components, the content of water extract, amino acid, caffeine, tea polyphenols, theophylein, theaflavin and theafronin in the black tea produced by 3 tea varieties at each process stage were measured, and the dynamic changes of their main physical and chemical components were analyzed. Results The results showed that the aroma, color and taste of tea samples from Bixiangzao and Zhuyeqi varieties were better in sensory evaluation. The content of tea polyphenols and thearubin in tea samples from Bixiangzao was the highest, which was 14.0% and 2.19%, respectively. Conclusion Comparing comprehensively, Bixiangzao cultivars are more suitable for the production of Huhong Congou black tea.
