Oolong tea originated in China, and is produced and consumed primarily in China and Taiwan. The production process for oolong involves allowing the leaves to begin to oxidize, as one would in the production of black tea. However, before the oxidation is completed, the process is stopped by heating (usually roasting). The degree of oxidation and level of roast both vary considerably, leading to many different varieties with widely variable colors, flavors, and aromas.

Oolong tea, also spelled wulong or wu long, is a type of semi-oxidized tea, meaning that it is intermediate between black tea and green tea. This article summarizes some basic facts about oolong tea, including health information and an introduction to different varieties.
