The San Xia Tian Cong (SXTC) green tea is produced in Wanzhou, Chongqing.It has a unique geographical location and quality advantages and is known as the representative of China’s high gorge among clouds tea.Until now, there have been no reports on the sensory quality of SXTC tea.This study used sensory quantitative descriptive analysis (QDA) to investigate the sensory characteristics of 29 SXTC green teas.Results showed that after the generation of attributes, discussion, M-value screening, and correlation analysis, the evaluation team identified 21 primary attributes from 119 descriptive attributes and constructed a sensory wheel and radar chart.The results of variance analysis and principal component analysis (PCA) showed that the 21 descriptive attributes could effectively distinguish and comprehensively evaluate the sensory characteristics of SXTC green tea.Among the 21 attributes, there were 6 most prominent sensory characteristics, namely chestnut aroma, clean and refreshing, umami, refreshing, sweet aftertaste, and chestnut flavor.The results of hierarchical clustering analysis (HCA) showed that bitter, astringency, umami, sweet, sweet aftertaste, and refreshing were the main characteristics to distinguish the different sensory qualities.This study provides a reference for the scientific evaluation of the sensory quality of SXTC green tea.
