Black tea is a tender leaf or bud of camellia sinensis. Black tea is not naturally grown, but is made on the basis of green tea in the late Ming and early Qing dynasties. It is a kind of tea refined by a series of technological processes such as withering, rolling (cutting) fermentation and drying. , make the ingredients in tea have a chemical reaction.

Green tea is a shrub or small arbor plant of Camellia of Theaceae, with natural appearance and green color. It is made of new leaves or buds of tea tree through the processes of deactivation, shaping and drying, and retains the natural substances of fresh leaves. Tea leaves have thin tips, smooth surface, white flowers and small polygonal flowers. The flowering period is 10-February of the following year.

The difference between black tea and green tea:

1, with different appearance.

Black tea is red leaf soup with bright red color, which is the quality characteristic of fermentation. The most representative ones are Ninghong and Dianhong, while green tea has the characteristics of green leaves and clear soup.

2. Brewing water temperature.

The brewing temperature of black tea is about 90 degrees of boiling water. For high-quality green tea, especially famous tea with tender buds, it is generally brewed with boiling water of about 80 degrees. When the water temperature is too high, vitamin C in tea is easy to be destroyed, and caffeine is easy to precipitate, which affects the taste.

3, the taste is different.

Black tea tastes very different from green tea. After black tea is fermented, tannin is solidified, insoluble in water, not as astringent as green tea, and more palatable. However, because most of the aromatic oil in tea has evaporated, it is not as fragrant as green tea.

4. Production process.

Black tea is fermented tea. Generally, it is made of suitable tea leaves after withering, rolling, fermentation, drying and other processes, while green tea is not fermented at all. After picking, it can be directly slaughtered, kneaded and dried.
