The boiling water can be boiled at the beginning, so that the freshness of the tea brewed is better. The water temperature of tea is required to be about 80, because the chlorophyll of high-quality green tea is easy to be destroyed and yellowed at too high temperature, and the tea polyphenols in the tea will also oxidize at high temperature to make the tea soup quickly yellow, and many aromatic substances will quickly volatilize and lose at high temperature, so that the tea soup loses its fragrance.
