Keemun is a type of black tea that originated in China's Anhui province. Some common synonyms for Keemun include Qi Men, Qi Men Hong Cha, Keemun Gongfu, and Keemun Mao Feng. These synonyms refer to high-quality Keemun tea leaves that are carefully processed to produce a smooth, rich, and slightly smoky flavor with a reddish-brown color. Qi Men Hong Cha, in particular, is often used to denote the highest-grade Keemun tea, while Keemun Gongfu refers to the tea's artisanal processing. For tea lovers looking for a stronger flavor, Keemun Mao Feng might be the perfect substitute with its bold, earthy flavor and stone fruit or nutty notes.
