Ten Ren's First Grade Dark Oolong consists of the finest oolong harvested during the premium seasons, spring and winter, and from the best area to grow oolong, the mountains of central Taiwan. Each tea leaf is handpicked to ensure harvests of young terminal buds. Because Dark Oolong is baked longer than Green Oolong, the steeped tea has a light golden brown hue, prominent roasted aroma with sweet undertones, the initial flavor of roasted chestnuts, and a strong lasting, sweet and roasted aftertaste which lingers at the back of the throat.
