The Muchagara cooperative is found in the heart of Kirinyaga. Each lot consists of coffees from hundreds of smallholders from the area surrounding the washing station (factory). The team at the factory sort the cherries before they go into production. The coffees are traditionally processed with dry fermentation, before being washed and graded in channels, and dried on raised beds. The farmers mainly grow SL28 and SL34, but as with almost all Kenyan cooperative coffees, there can be a mix of everything. Other common cultivars are K7, Ruiru 11 and now also Batian.
