Oolong is a traditional semi-oxidized Chinese tea (Camellia sinensis) produced through a process including withering the plant under strong sun and oxidation before curling and twisting. Most oolong teas, especially those of fine quality, involve unique tea plant cultivars that are exclusively used for particular varieties. The manufacture of oolong tea involves repeating stages to achieve the desired amount of bruising and browning of leaves. Withering, rolling, shaping, and firing are similar to black tea, but much more attention to timing and temperature is necessary.
