INTRO
Boma Washing Station, operated by the Boma Farmers Cooperative Society in Tenwek, roughly 80km west of Kericho in Kenya's Rift Valley — prune and blackcurrant depth meet the bright citrus character of pomelo, creating a layered, expressive fruit profile. In the cup: prune, blackcurrant, and pomelo.
THE PRODUCER
Established in 1999, Boma Farmers Cooperative Society serves surrounding smallholder farmers and currently consists of 1,346 members, producing around 850,000 kilograms of coffee cherries annually. Women and young farmers make up a significant portion of the membership, with female representation in both management and the cooperative's board. Overseen by a nine-member board of directors and three supervisory committee members, the cooperative employs eight full-time staff year-round and up to 48 workers during the peak September-to-December harvest season. Most members manage small farms with approximately 300-400 coffee trees, growing SL28, SL34, and Batian on fertile volcanic soils under reliable rainfall and cool mountain temperatures — conditions that slow cherry maturation and contribute to the cup's distinctive quality and complexity.
THE PROCESS
Freshly harvested cherries were depulped and processed using the washed method. Following fermentation, the coffee was thoroughly washed, then dried on raised African beds for 14-21 days until reaching approximately 10-12% moisture, before hulling and grading.
The slow, cool-climate cherry maturation is the defining factor here — it's what builds the layered complexity behind the prune and blackcurrant depth, with a bright pomelo citrus character cutting through.
THE CUP
Layered and expressive — prune and blackcurrant depth up front, with a bright pomelo citrus character rounding out the finish. A classic, community-rooted expression of Kericho's terroir.
