Kagumo Coffee Factory sits in Kirinyaga County, on the western slopes of Mount Kenya and opposite the Aberdare Ranges. This position places the factory in one of Kenya’s most suitable coffee-growing areas. Red volcanic soils, steady rainfall, and cool temperatures support slow cherry development and balanced maturation.
The factory lies about 115 kilometres north of Nairobi. It serves farming communities from the Mutira and Kanyekiini catchment areas, where coffee has long played a central role in rural life.
Kagumo is affiliated with the Mutira Farmers Cooperative Society, a long-established cooperative in Central Kenya. Founded in the early 1950s, the society has supported smallholder farmers for decades through shared infrastructure and collective organization.
Today, Mutira Farmers Co-operative Society operates nine washing stations across Kirinyaga. Seven elected management committee members lead the society, while three supervisory committee members provide oversight. Together, they ensure accountability and farmer representation.
Kagumo is one of the largest washing stations within the cooperative and serves around 1,500 active smallholder farmers. Most farmers manage very small plots, averaging about 0.1 hectares.
Coffee provides an important source of family income. At the same time, farmers grow food crops such as maize, beans, potatoes, vegetables, fruits, and bananas for household use. In addition, many farmers cultivate tea as a secondary cash crop. This mix helps reduce risk and supports year-round stability.
Farmers carry out all agronomic work on their own plots. They follow guidelines from the Coffee Research Station and receive support from the Ministry of Agriculture. Typical field activities include pruning, weeding, spraying, fertilizing, mulching, and regular maintenance.
Moreover, farmer training programmes and field visits provide technical guidance throughout the season. A dedicated field committee monitors compliance with cooperative standards. For example, the committee restricts intercropping with maize and beans to protect coffee quality. However, it allows macadamia and Grevillea trees, which provide shade and long-term benefits.
Farmers selectively handpick ripe cherries and deliver them to the factory on the same day. This practice preserves freshness and limits quality loss. Upon arrival, factory staff supervise sorting to remove underripe and overripe cherries.
Once intake ends, processing begins. The factory uses a fully washed Kenyan method. After pulping, the coffee undergoes dry fermentation for around 24 hours. Staff then wash the coffee using clean river water sourced from the Mount Kenya forest system.
After washing, the coffee soaks in clean water for about six hours. This step supports clarity and balance. Finally, workers dry the coffee on raised beds, while they regularly monitor moisture levels to ensure even drying.
The factory uses clean river water throughout processing. Importantly, staff recirculate the water before disposal. They release wastewater into seepage pits, which helps prevent contamination and protects the surrounding environment.
Kagumo places strong emphasis on transparency. Staff weigh each cherry delivery and digitally record the results. The system sends this information directly to the farmer’s mobile phone. As a result, farmers can track deliveries and payments with clarity.
Staffing levels change with the season. During peak harvest, the factory employs several casual workers. Outside the harvest, only a small team remains. Permanent staff handle weighing, grading, farmer payments, and daily communication with members.
Beyond processing, the factory supports farmers through input credit schemes and cash advances. These services help farmers manage costs during the season and reduce financial pressure before payments arrive.
Kagumo’s coffee grows at 1,600 – 1,700 metres above sea level in red volcanic soils. The area receives around 1,100 mm of rainfall each year. Temperatures remain moderate, typically between 16 and 26°C.
Shade trees and mixed farming systems improve soil health and biodiversity. Together, these conditions support stable production and long-term farm resilience.
Through cooperative organization, disciplined processing, and transparent systems, Kagumo delivers consistent washed Kenyan coffees. The station reflects a balance between quality focus and community-led sustainability on the slopes of Mount Kenya. Expect expressive profiles of citrus and berry fruit, high sweetness, and floral aftertaste.
