Of all the black teas available in China, Keemum is probably one of the most well known. Keemun black tea was produced only after 1875 due to the demand of the English’s preference of black teas over green teas at the time. Keemun rapidly became an English staple after its production. This organic tea has a complex and subtle flavor that’s aromatic and penetrating without being lush or floral. USDA Organic.
