Abstract:

Ten tea cultivars from the hilly areas of Jiangsu Province were selected to study their processing suitability for Congou black tea based on the comparative analysis of the physical properties, processing properties, quality components and sensory quality of fresh leaf raw materials and finished black tea. The results show that the (TF+TR)/TB value of ‘Fuding-dabai’, ‘Fuding-dahao’, ‘Jinguanyin’, ‘Longjing43’ and ‘Baiye No.1’ are higher than 1.05, and their tea soup aroma, taste and brightness are satisfactory. ‘Zhenong 113’ and ‘Chuyeqi’ have aesthetic appearance and moderate inner qualities, which are suitable for making Congou black tea. However, ‘Wuniuzao’, ‘Longjingchangye’ and ‘the small leaf population varieties of tea population cultivar’ are unsuitable for producing Congou black tea because of poor fermentation performance and incongruity of quality components. Among the tea cultivars suitable for Congou tea processing, ‘Jinguanyin’ is of charming aroma but rather unsatisfied appearance quality, and ‘Baiye No. 1’ is of fresh and sweet soup but slower fermentation process. These two cultivars have distinctive characteristics, and are suitable for the further development of characteristic Congou black tea.

Key words: the hilly areas of Jiangsu Province, tea cultivars, Congou black tea, quality components, sensory quality, processing suitability
