Cultivated in China and Taiwan, oolong teas come from the Camellia sinensis plant, like white, black, and green tea leaves. Oolong loosely translates to "black dragon," named for the coiling shape of the semi-oxidized leaves.
The benefits of oolong tea are true of all teas: EGCG, antioxidants, L-theanine, and other compounds support overall mental and physical well-being. Is there caffeine in oolong tea? Tea leaves contain a range of caffeine between 15 and 60 mg per cup, vs. almost 100 mg in a cup of coffee. The oxidation process is responsible for the unique oolong tea taste, with complex floral, bright, and creamy notes.
