Located in Gatundu, Kiambu County, the Wamuguma Coffee Factory operates under the Ritho Farmers' Cooperative Society (FCS), which was established in 1972. Ritho FCS is made up of nine board members and manages two factories—Wamuguma and Handege-both known for producing exceptional coffees from Kenya's central highlands. At Wamuguma, freshly harvested coffee cherries are delivered directly by smallholder farmers and undergo the traditional washed (wet) process. Water for pulping and recirculation is pumped into holding tanks using a diesel engine. After pulping, the coffee is fermented overnight, then thoroughly washed and soaked, before being carefully spread on raised drying tables. The parchment is frequently turned, sorted by hand, and stored in optimal conditions while awaiting delivery to the dry mill. The factory has made key investmentsin infrastructure, including a mechanical pulper,a recirculation system, and 10 conditioning bins, to ensure quality and efficiency throughout processing. Like many of Kenya's high-quality microlots, coffees from Wamuguma are traceable to the factory level, and sometimes even to individual farmers, depending on the lot. Most farmers in the region own between 1/8 to 1/4 hectare of land, meaning their daily harvests are small and are processed collectively into "day lots".These are blended at the factory by date and cupped intensively. Our green buyer resides in Kenya during the harvest season to taste hundreds of samples, selecting only thetop-performing lots—usually fewer than 100 bags—to purchase as microlots. Wamuguma is situated in Kiambu County, Kenya's most productive coffee-growing region. Kiambu benefits from abundant rainfall, cool highland temperatures, and fertilered volcanic soils—especially in the uplands where coffee thrives. A region with deep agricultural roots and a long-standing coffee and tea trade history, Kiambu today features a blend of both smallholder farms and large estates. Its coffees are famed for their bright acidity, complex character, and distinctive notes of Berries and currants, which continue to define Kenya's place on the world coffee map.
