Black Teas are usually fermented between 60% and 80% and are processed using specialized techniques that bring out unique and satisfying aromas, tastes, and colors. When brewed, the tea color ranges from dark brown to a gorgeous deep red, from which it gets its Chinese name, Red Rea, or Hong Cha. Some Black Yeas are robust and woodsy, while others are delicate with a perfume-like fragrance that fills the room.
