Oolong teas are a wide variety of semi-oxidized teas with a diverse range of flavors, aromas, and styles. The most well-known Oolongs are grown in Wuyi Mountain and Anxi County in Fujian, Phoenix Mountain in Guangdong, and all across Taiwan. These teas come in a wide range of styles and have a vast array of flavors and aromas, but are all similar in their 15-85% oxidation state.
Because of the large variety of oolong teas, it is impossible to generalize their flavor. However, lighter-oxidized oolongs tend to be more delicate and floral tasting similar to green teas, while heavier-oxidized oolongs are more intense and robust like black teas.
