Combined with the above common classification methods, China tea can be divided into two parts: basic tea and reprocessed tea:
Basic tea:
Green tea-This is the largest tea produced in China, and its variety ranks first in the world. Green tea has the characteristics of high aroma, mellow taste, beautiful appearance and resistance to brewing. Its production process includes the processes of enzyme fixation, rolling and drying. Due to the different drying methods in the processing, green tea can be divided into fried green tea, baked green tea, steamed green tea and sun-dried green tea.
Green tea is a kind of tea with the largest yield in China, and it is produced in all tea-producing provinces (regions) in China 18. China has the largest variety of green tea in the world, exporting tens of thousands of tons every year, accounting for about 70% of the green tea trade in the world tea market. China traditional green tea-plum tea and pearl tea, with high aroma, mellow taste, beautiful appearance and resistance to brewing, are well received by consumers at home and abroad.
Black tea-The difference between black tea and green tea lies in the different processing methods. When black tea is processed, it will wither, so that fresh leaves lose some water, and then it will be kneaded (kneaded into strips or cut into granules) and fermented, so that the tea polyphenols contained in it will be oxidized and become red compounds. This compound is soluble in water and insoluble in water, but it accumulates in leaves, thus forming red soup and red leaves. There are three main kinds of black tea: competition black tea, kung fu black tea and red broken tea.
Green tea (oolong tea) belongs to semi-fermented tea, which is a kind of tea between green tea and black tea. Both the freshness of green tea and the sweetness of black tea. Because its leaves are green in the middle and red in the edge, it is called "green leaves with red edges".
White tea is a specialty of our country. When processing, do not fry or knead, only dry the delicate tea leaves with fine hairs on the back or dry them with slow fire, so that the white fine hairs can be preserved completely. White tea is mainly produced in Fuding, Zhenghe, Songxi and Jianyang counties in Fujian. There are several kinds of white tea, such as Silver Needle, Bai Mudan, Gongmei and Shoumei.
Yellow tea-in the process of making tea, yellow leaves and yellow soup are formed by boring. It can be divided into "yellow bud tea" (including the silver bud of Junshan in Dongting Lake, Hunan Province, the yellow bud of Mengding in Ya 'an, Sichuan Province, and the inner bud of Huoshan in Anhui Province), "yellow tea" (including Beigangzai in Yueyang, Hunan Province, Maojian in Weishan, Ningxiang, Tanghuang in Pingyang, Zhejiang Province, and Luyuan in Yuan 'an, Hubei Province) and "yellow tea" (including Dayeqing in Anhui Province and Huang Da in Huoshan).
Black tea-the raw materials are coarse and old, and after a long period of accumulation and fermentation during processing, the tea leaves are dark brown. It is an indispensable daily necessity for Tibetan, Mongolian, Uygur and other fraternal peoples. There are Hunan Black Tea, Hubei Old Green Tea, Guangxi Liubao Tea, Sichuan West Road Side Tea, South Road Side Tea, Yunnan Compact Tea, Flat Tea, Square Tea and Round Tea.
Reprocessed tea:
Additive tea, which is made from various kinds of crude tea or refined tea, includes scented tea, pressed tea, liquid tea, instant tea and medicinal tea.
Medicinal tea-Medicinal tea is made by mixing medicines with tea leaves, so as to exert and strengthen the efficacy of medicines, promote the dissolution of medicines, increase the aroma of medicines and coordinate the taste of medicines. There are many kinds of this kind of tea, such as "afternoon tea", "ginger tea powder", "longevity tea" and "slimming tea".
Scented tea-this is a rare tea color. It is a product that enhances the fragrance of tea with floral fragrance, which is very popular in China. Generally, green tea is used as tea blank, and a few people use black tea or oolong tea as tea blank. It is made of fragrant flowers and fragrance according to the characteristic that tea easily absorbs peculiar smell. There are several kinds of chemicals used, such as jasmine and osmanthus, among which jasmine is the most.
From a global perspective, among the above teas, black tea is the most, followed by green tea, and white tea is the least.
