Oolong tea is a traditional Chinese tea but it is yet undiscovered by many people.

- It is a partial oxidized tea that falls somewhere in between dark and green teas and combines the qualities of both teas.
- All teas are made of leaves from the Camellia sinensis. The Camellia sinensis sinensis is a small-leaved plant native to China and is commonly used for green and white teas. The Camellia sinensis assamica is a larger-leaved plant typically used for black and oolong teas.
- The color and taste of oolong tea can vary greatly depending on the degree of oxidation.

Oolong tea no. 17 is a more processed tea than oolong tea no.12 because it has been rolled for a longer time, so it presents a stronger flavor and color.
