Muthuthuini is operated by the Ruthaka Farmers Cooperative Society, which has 3,557 members delivering coffee cherries to seven washing stations. The farmers in this area of Nyeri grow coffee in fertile red volcanic soil. Coffee in Kenya is typically traceable down to the factory, or mill level: most farmers own between 1/8 to 1/4 of a hectare, and often grow crops other than coffee as well, which means they rely on a central processing unit for sale and processing of their coffee.
Producers deliver coffee in cherry form to a factory, where the cooperative will sort, weigh, and issue payment for the delivery. The coffee is then blended with the rest of the day's deliveries and goes on to be processed. Because of this system, which serves many hundreds of smallholder farmers per factory, there is limited traceability down to the individual producers whose coffee comprises the lots.
