What's the difference between black tea, green tea and black tea?

Black tea: Black tea belongs to fully fermented tea. It is made of one bud, two leaves or three leaves through withering, rolling, indoor full oxidation, fermentation and finally drying. In the process of fermentation, polyphenols in tea are oxidized to produce black tea pigment, which makes black tea have the characteristics of soup red leaves. Black tea is divided into three categories: ethnic black tea, kung fu black tea and red broken tea. Black tea is very popular among European and American consumers. It is the largest tea trade product in the world and the second largest tea in China.

Green tea: Green tea is a kind of non-fermented tea, which has the widest production area, the largest output and the best variety in China. Green tea production accounts for about 70% of the total tea production in China. Green tea can be divided into steamed green tea, baked green tea, fried green tea and sun-dried green tea according to the different ways of fixing and drying in the initial process. Fixing green tea is the key process in the initial production of green tea. Enzymatic oxidation of polyphenols can be prevented by high temperature deactivation, and the characteristics of green tea, green leaves and green soup can be maintained.

Black tea: Black tea belongs to post-fermentation tea, which is unique to China and has a long history of production. Mainly produced in Hunan, Hubei, Sichuan, Yunnan, Guangxi and other places. The main varieties are Hunan black tea, Hubei old green tea, Sichuan border tea, Guangxi Liubao tea and Yunnan Pu 'er tea. Among them, Yunnan Pu 'er tea enjoys a long-standing reputation at home and abroad. Black tea is made from coarse and old raw materials through four primary processes: deactivation, rolling, fermentation and drying. Stacking fermentation is the key process to determine the quality of black tea. The length and degree of stacking fermentation will make the quality and style of finished tea have obvious differences. Black tea pressed tea, such as brick tea, cake tea, Tuo tea and Liubao tea, is an indispensable drink for ethnic minorities.
