Black tea, as a representative of fully fermented tea, during the production process of black tea, the tea polyphenols in the tea leaves undergo a full oxidation reaction and are converted into new components such as theaflavins and thearubigins, which give black tea its unique color and aroma. The dry leaves of black tea are dark in color, the tea soup is bright red, the aroma is long lasting and sweet, and the taste is mellow and slightly sweet after taste.
In contrast, oolong tea is a semi-fermented tea, and its degree of fermentation is between that of green tea and black tea. The production process of oolong tea is complex and delicate. Through processes such as shaking green, the tea leaves are partially oxidized under hot and humid conditions, thus forming a unique aroma and taste. Oolong tea not only retains the fresh aroma of green tea, but also combines the mellow taste of black tea, forming a unique floral and fruity aroma. The color of the tea soup is bright orange, clear and translucent, and the taste is fresh and sweet, which is endless aftertaste.
