Withering strengthens the activity of enzymes, so that tea polyphenols are fully oxidized during rolling and fermentation, forming a unique color, aroma, and taste. High-temperature drying destroys the activity of enzymes, so that the unique quality formed can be fixed. Its quality characteristics are red soup and red leaves. According to its appearance and quality, there are small black tea, broken black tea, and Kung Fu black tea. After fresh Pu'er tea leaves are picked, a large amount of pesticides and bacteria will be attached to the tea leaves.
