China tea is mainly divided into green tea, black tea, oolong tea, white tea, yellow tea and black tea.

1, green tea

Main varieties: Yingshan Yunwu Tea, West Lake Longjing Tea, Emei Xueya, Meitan Cui Ya, Lan Xin Queshe, Huiming Tea, etc.

Green tea is one of the main tea leaves in China, which refers to a beverage made from the new leaves or buds of tea trees without fermentation, and through the processes of enzyme fixation, shaping and drying. The color of the finished product and the brewed tea soup retain the green style of new tea.

2. Black tea

Main varieties: Rizhao Black Tea, Qi Hong, Zhaopinghong, Huohong, Dianhong, Yue Hong, Quanchenghong, Quanchenglv, etc.

During the processing of black tea, a chemical reaction centered on the enzymatic oxidation of tea polyphenols took place, and the chemical components in fresh leaves changed greatly. Tea polyphenols decreased by more than 90%, resulting in new components such as theaflavins and thearubigins. Compared with fresh leaves, the aroma substances increased obviously.
