Keemun is produced exclusively in the Qimen County in the south of Anhui province. The name of the tea is an older Western spelling of the name of the nearby town, Qimen (pronounced Chee-men). The tea-growing region lies between the Yellow Mountains and the Yangtze River. The cultivar used for Keemun is the same as that used in production of Huangshan Maofeng. While the latter is an old, well-known variety of green tea, Keemun was first produced in 1875 using techniques adapted from Fujian province farmers.
