It is the quality characteristic formed by fermentation, the most representative ones are Ninghong and Dianhong, while the color of green tea is bright and green,the bud peaks are revealed, the soup color is bright, and it has the characteristics of green leaf clear soup. The representative varieties are Longjing and Biluochun.
2. Brewing water temperature
The brewing water temperature of black tea is about 90 degrees of boiling water, while for high-quality green tea, especially the famous tea with delicate buds and leaves, it is generally used about 80 degrees of water. Brewing in boiling water, if the water temperature is too high, it is easy to destroy the vitamin C in the tea, and the caffeine is easy to precipitate, which affects the taste.
3. Difference in taste
The taste of black tea and green tea is quite different. After the black tea is fermented, its tannin is solidified and insoluble in water, so it is not as astringent as green tea, which is more suitable for drinking.  However, since most of the aromatic oil in the tea has evaporated, there is no green tea fragrance.
4. Production process
Black tea is fermented tea, which is generally refined from suitable tea tree sprouts and leaves through typical processes such as withering, rolling, fermentation, and drying. Green tea does not go through any fermentation process when it is made. After picking, it can be directly killed, rolled and dried.
