The Kimatu processing station is owned by the Rwama Farmers Cooperative Society and is located in the Njuki-ini ward of 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 800 small producers deliver their crops to Kimatu, 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.
