Depending on the degree of fermentation, it can be divided into light fermented tea, semi-fermented tea, fully fermented tea and post-fermented tea.



Lightly fermented

The tea doesn’t undergo fermentation process. Green tea is the lightly fermented tea. Because it is not fermented, it has a natural smell, refreshing aroma and bright green color. Green tea can be divided into two types depending on the process: one is made by steaming and then drying, which is called sencha; the other is made by frying in a pot, such as longjing tea and pearl tea. Sencha will gradually lose its color and flavor due to long storage, but fried green tea does not have this disadvantage.


Semi-fermented tea is made by destroying chlorophyll in the tea leaves and fermenting them from 20% to 70%, such as Tieguanyin and Wuyi Rock Tea. Semi-fermented tea is made by withering in the sun, withering in the room, frying, kneading and drying. It is very distinctive because it has both the freshness of green tea and the fruitiness of black tea. This tea is partially fermented, so the leaves have a special beauty of "green leaves with red edges".
