Oolong sits between green and black tea on the oxidation spectrum, typically 15-85% oxidized, giving it the widest flavor range of any tea category. Lightly oxidized oolongs (High Mountain, Jade) taste floral and creamy; heavily oxidized ones (Da Hong Pao, Dan Cong) taste roasted, fruity, and complex. Oolong is the artisan's tea: labor-intensive to produce and deeply rewarding to explore cup by cup.
