Keemun is a historically well regarded black tea in China. It is known since Qing Dynasty and originated in Keemun County (祁门县 Qimen Xian) and surrounding areas at Anhui Province (安徽省 Anhui Sheng). In the past, Keemun was mainly exported overseas, especially Europe and United States. At the begining of 20th century the price of Keemun at the New York Stock Exchange hit record high figures which made Keemun tea the most expensive tea at that time and only upper class could afford to enjoy it. The Imperial and Noble Families used to treat it as a fashionable exotic beverage. It was said that Keemun was presented to Queen Victoria as the Gift Tea during Her birthday. In United States it was the everyday-tea for the President Roosevelt and his spouse. We're focusing on Keemun produced in the original production area of Keemun County which is located at the province nature preserved park at Anhui Province from genuine cultivar called Zhu Ye Zhong (槠叶种). There are many other cultivars being used to produce Keemun. However, different cultivars at other growing environment and difference in manufacturing techniques make those teas significantly lower in quality in comparison to genuine Keemun tea.
