There are 2 categories within this classification.
 
They are what is commonly also known
 as green oolong and black oolong.
The green oolong is also commonly and rather loosely termed as green tea.
How green oolong is achieved is dependent on the tea master
who handles the processing.
Unlike coffee crops that are sold prior to harvest, tea crops are sold only
 after the tea is harvested,
processed and the taste test is conducted.
The final product sold is dependent on the quality of the end product.
Therefore, the tea quality is dependent on factors like weather, seasons
 and the final processing by the tea maker.
Freshly roasted green oolong is vacuum packed to preserve its freshness.
Black oolong is achieved by re-roasting the old green oolong.
