Oolong tea, basically originating from China, is a traditional beverage of Asian countries. The name oolong is derived from Chinese word, Wulong Cha, which means black dragon tea. In ancient times, it was also known as Qingchatea. It is extracted from the plant camellia sinensis by following a similar course of withering and processing as done for other tea varieties. But, Oolong is slightly more oxidised than green tea and somewhat lesser than black tea.
Though it is manufactured by following the same procedure of withering, rolling, curling, and roasting but the change in timing and the temperature at which it is processed makes all the difference. An exclusive method of baking and roasting is applied to oolong tea. It is a complex traditional technique to create this medicated and highly advantageous tea.
Oolong tea is oxidised between 8% and 85% (approx.) according to the custom of its respective province. China oolong tea is lesser oxidised while Taiwanese variety that is more tilted towards black tea with higher oxidisation. Differences in region, horticulture, and styles of production have a huge impact on the flavor of oolong tea. Its aroma can be sweet, fruity, woody, etc. depending on the tradition followed by the manufacturer.
