Nkaka was built in 1979 in the Mwumba Commune in the Ngozi province. It lies at an altitude of 1675m. It is named after the small Nkaka River that passes through the region. Legend has it that men would go to this river after drinking too much beer to sober up before going home. If they arrived late and were asked where they had been, they would say that they had come from 'Nkaka'. This washing station collects cherries from over 2400 local coffee farmers spread over the 13 neighboring colonies. During the harvest season, Nkaka processes more than 1200 tons of coffee. In the cup, this coffee has a perfectly balanced profile.
