The Nduma factory is part of the Ruthaka Farmers Cooperative Society. The factory lies at 3km from the town of Mukerwe-ini. Nduma factory lies at around 1750 meters above sea level. The factory services around 600 smallholder producers in the direct region nearby. These producers farm coffee at varying altitudes between 1650 and 1850 meters above sea level. Most common varieties in the region are SL28 and SL34, with some Ruiru 11 left and right. Nduma factory is blessed with a supply of water from the nearby Ruarai river. The factory has water treatment ponds in place so the wastewater does not contaminate the water network.
The producers deliver their cherries to the central washing station. Kiungu will take care of the wet processing in typical Kenyan style. The cherries are sorted on maturity and processed separately per quality group. The coffee is depulped and ferments for 24 to 36 hours, depending on the environmental temperature. When the mucilage has broken down sufficiently, the washing station staff will open the tanks to the washing channels. Here, they wash and grade the parchment by pushing it through a long channel. The lowest quality, lightest beans will float all the way to the end. This makes it easy to remove defect beans. The highest quality, heaviest beans will remain at the start of the channel. The highest qualities are soaked for an additional 24 hours in clean water before being carried out into the drying field. The coffee will dry on raised beds for an average of 16 days.
When the coffee has dried to 11% moisture content, marketing agents collect samples to sell the lot at the Nairobi Coffee Exchange. In this auction, registered buyers are able to bid on the coffees they liked. Each buyer can take samples from the auction’s sample room to evaluate in his own lab, a week prior to the auction.
