Long lasting cups of this remarkably strong, full - bodied tea are both stimulating and delightful. This WuYi Mountain rock wulong is named Rou Guior ‘cassia bark’ because the tea’s famous fragrance is akin to the cassia tree’s spicy, cinnamon - like bark. Long, tightly rolled leaves of a lustrous deep dark green - brown give birth to golden - brown liquor. This and all of our other WuYi Mountain rock wulongs are certified organic.
