Oolong Tea is a nice middle ground between Black Tea and Green/White teas. It undergoes some oxidation but not a lot.
If you are looking for a full bodied tea - think a petite syrah version of tea - Black Tea is the way to go. Black Tea is the tea that is traditionally thought of. Black Tea is the most common tea in the western world and readily available in loose form as well as tea bags. Black tea is meant to be brewed at a higher temperature than green or white counterparts. Green Tea, White Tea, and Oolong Tea all come from the same plant but different levels of oxidation and different preparation methods mean different flavors are produced.
