You've tried green and black (and perhaps white and jasmine too), now how about oolong tea? With the fragrance of green tea and the smoothness of black tea, oolong tea is full-bodied, sweet, and reminiscent of stone fruits like apricots. Although it is traditionally served hot, I think oolong also makes particularly good iced tea.

What Is Oolong Tea?

Like all true teas, oolong tea is produced from the leaves of a shrub called Camellia sinensis. Primarily grown in China and Taiwan (Formosa), this tea is also known as wulong, which means "black dragon."

Whereas green tea is not oxidized and black tea is fully oxidized, oolong tea is semi-oxidized to varying degrees between 10 and 80 percent. (It is sometimes referred to as semi-fermented but fermentation is a misnomer.) Oolong is always a whole-leaf tea with the leaves being open, rolled, or curled.

Varieties of Oolong Tea

The aroma and flavor of oolong tea can vary depending on where it is grown, when it is plucked, and how it is processed. The color of the infusion can also vary; less oxidized teas have a lighter, more golden color, while more oxidized teas have a darker, orange or brown color.

Here are a few oolong teas to look for:

Oolong Tea and Health

Oolong tea is sometimes touted as a "weight loss" tea. Studies have indicated that drinking oolong tea may increase energy levels, improve metabolism of lipids, and lower blood sugar.

The caffeine level of oolong tea can vary widely based on the level of oxidation, but it is generally between that of green and black tea.
