Black tea is a novelty in China compared to other genres of tea. Legend has it that it was accidentally produced when the farmers had to leave their tea mid-production because of an invasion. Because of this the leaves oxidised resulting in a darker and more fragrant tea, which later became well loved by both the Chinese and the Europeans trading with them.
Chinese black tea is mostly very sweet and malty compared to its Indian counterparts. Fruity notes are also fairly common.
