Oolong teas are semi-oxidized, rolled, twisted or curled into balls or thin strands. The shaping technique depends on the tea master making the tea. Rolling is important in oolong tea because it alters the appearance, color, and aroma of the tea leaves. Darker oolongs produce a warm and toasty flavor and lighter oolongs have a more delicate flavor. Free customized sample and disposable tea filter included with every order.
