Abstract: 78 samples of different grades（including top famous tea and special famous tea in Zhejiang province）were collected in this research. Through the sensory evaluation, an obvious flavor changes between different grades were found. While processing the data of chemical compounds in different grade samples with discriminant analysis, a well judgment can be shown, which is essentially in agreement with the sensory evaluation result. The quantity of samples with different aroma and taste types was counted, and then the characteristics of each tea were summarized. Flavor wheels were drawn after the analysis and reconstitution of the flavor types.

Key words: top famous tea, sensory evaluation, flavor, flavor wheel
