The Kainamui processing station is owned by the New Ngariama Farmers Cooperative Society and is located near the town of Ngariama in Kirinyaga County. Kirinyaga lies in central Kenya, south of Mount Kenya, along with the neighbouring Nyeri Province it is the home of Kenya’s most complex coffees.

During the harvest period, approximately 1,800 small producers deliver their crops to Kainamui, where the coffee cherries are immediately sorted and separated according to various criteria. Upon reception, cherries are de-pulped and then fermented the following night. Fermentation is a microbial

process, during which various wild yeasts and bacteria help to break down the slimy, sugary layer attached to the seeds of the fruit. This is followed by repeated washing and drying for 9-13 days.
