It is of great significance for the production and popularization of yellow tea with standard grade difference. In this paper, 9 yellow tea samples of 3 categories (yellow bud tea, small-leaf yellow tea, large-leaf yellow tea) from western Anhui province were selected. Then 80 consumers and 22 assessors were recruited to analyze these samples using ranking and Napping-UFP respectively. The results show that the 8 standard samples can be distinguished according to the appearance by ranking, except the super class and the first class of bud tea. In Napping-UFP, 22 assessors could distinguish different grades of samples by appearance. The categories (yellow bud tea, small-leaf yellow tea and large-leaf yellow tea) and the roasting degrees (light fire and sufficient fire) could be accurately distinguished based on their aroma or taste. At the same time, the assessors provided relatively rich descriptive terms (33 of appearance, 21 of aroma and 24 of taste), including "green", "yellow" and "fairly stalk" in the appearance attributes, "tend aroma", "sweet aroma" and "tobacco" in the aroma attributes, and "fresh" in the taste attributes. These terms could be used to accurately assess yellow tea from western Anhui province, which is conducive to consumers’ understanding and acceptance, as well as the market promotion of yellow tea from western Anhui province.
