Oolong leaves are processed immediately after picking. Typically, the leaves are first laid out in the sun to dry and then placed into baskets and shaken, which “bruises” the leaves. The leaves are then spread out again under the sun to begin a partial oxidation process, however the process is halted after two hours or so the leaves may be fired in hot woks. Ultimately, an Oolong will have crisp, dry leaves
