Because the boiling point of green tea is generally low, the amount of tea added to famous green tea is less than that of black tea, and the water temperature is also lower than that of black tea. According to relevant data, due to the low boiling point of green tea, the consumption of famous green tea is generally less than that of black tea, and the water temperature is also lower than that of black tea. Due to the influence of raw materials and technology, once green tea and yellow tea are brewed, the taste is quick, and the extract in tea leaves comes out quickly, so the consumption of green tea and yellow tea does not need too much. Green tea is one of the main teas in China. Green tea is made from the new leaves or buds of tea trees without fermentation, through the processes of deactivation, shaping and drying. It retains the natural substances of fresh leaves, and contains nutrients such as tea polyphenols, catechins, chlorophyll, caffeine, amino acids and vitamins. The color is green, and the tea soup retains the green style of new tea, hence the name.
