According to “The Classic of Tea” written by Lu Yu in Tang dynasty, “tea serves as a drink, originating from the Shen Nong peroid.” Tea drinking emanates from China and has become a “national drink” and an impartible part of Chinese life.

Based on the historical records, the history of tea making can be traced back to the Zhou dynasty. Tea is used in many different methods in various periods. In Zhou dynasty, fresh tea leaves were used as tribute; in the Western Zhou dynasty, tea was used as a sacrifice; during the Spring and Autumn Period and the Warring States Period, tea was considered as food and medicine; in the Western Han dynasty, tea was traded as the main commodity; in the Western Jin dynasty, tea was used as a soup drink. Later on, in the Tang dynasty, the emergence of steamed compressed tea marked the birth of the first tea category in history—green tea; then in the Song dynasty, steamed loose green tea was invented, and then in the Ming dynasty, fried green tea, yellow tea, black tea, and dark tea were created. Afterwards, in the Qing dynasty, white tea and oolong tea were created. China is vast in territory, thus teas in different regions have different characteristics and producing techniques. So far, the six major types of teas are formed, which are green tea, black tea, oolong tea, white tea, yellow tea, and post-fermented tea ( or dark tea).

The six types of tea are classified according to different processing techniques. The most fundamental reason is that the biochemical reactions of the substances in the tea during the producing process finally show that these substances have different contents and proportions and produce new materials, such as different teas have different amounts of flavanols and catechins.

One example is the difference between green tea and black tea. The process for making green tea is withering, fixation, twisting and drying, while the process of making black tea is withering, twisting, fermentation and drying. Therefore, the taste of green tea is relatively sweet, with the characteristics of “green leaf and green tea soup”, with a tender fragrance or roasting aroma; and the taste of black tea will be more stimulating and thicker than that of green tea, with the characteristics of “red leaf and red tea soup”, which has a rich floral and fruity flavor. In essence, their contents and proportions are different. For green tea, after heating, tea polyphenols are not substantially oxidized, so the soup color of green tea shows chlorophyll and other non-processed pigments’ (anthocyanin) color. For black tea, after the fermentation process, most of the tea polyphenols are oxidized into the pigments produced by theaflavins, thearubigins and others, meanwhile, a large amount of aroma substances are also generated, hence the black tea soup will be orange or bright red, and the aroma is also stronger than that of green tea.

Green tea
