Oolong Tea is also called “semi-fermented “tea and mostly produced in China and Taiwan. The
mature tea leaves were plucked and processed immediately. They are wilted in direct sunlight,and
then shaken in bamboo baskets to bruise the edges of the leaves. The next stage is to dry them indoors to promote fermentation.
The fermentation is stopped when 30% of leaves turn to red. This kind of oolong tea is also called green Oolong.
If the fermentation is stopped when 70% of leaves turn red, this kind
of tea produced is called black Oolong tea.
