The Kamwangi Factory (wet mill) is one out of two wet mills of the “New Ngariama Cooperative Society” in Kirinyaga.
The factory was registered in 1997. Kirinyaga is located on the slopes of Mount Kenya and is neighboring the well-known region Nyeri.
Cherries are hand sorted for unripes and overripes by the farmers before they go into production. The coffees are graded by density into 3 grades by the pulper. The coffee is fermented for 16-24 hours under closed shade. After fermentation the coffees are washed and again graded by density in washing channels and then soaked under clean water from the stream for 16-18 hours.
After soaking, the coffees are skin dried at hessian mesh mats for skin drying up to one day. After a day the coffees are moved to the traditional drying tables. The coffee is then normally dried on a surface of jute clothing or shade net on top of the wire mesh.
