Community Context

Yellow Diamond is Habil Olaka’s family farm in western Kenya, a 30-acre property with about 21 acres of coffee across four distinct blocks. Habil moved his family out from the city to Trans-Nzoia county with corn, chickens, flowers, and honey before coffee gradually claimed the bulk of his attention, encouraged in part by nearby producers like Stephen Nendela of Muinami Estate. Today, though an abundance of fruits, flowers, and an apiary (reached through a small banana grove) remain on the farm, the focus is optimizing for coffee. Soil has been tested and enriched with compost from coffee husk chicken manure, and shade trees of macadamia and Grevillea planted to provide both shade and wind protection.

Ruiru 11’s stability, productivity, and cup potential when paired with meticulous processing have made it the farm’s preferred variety, though Batian remains in play as well. When we visited the washing station just after the 25/26 harvest season, the place was immaculately clean, and detailed temperature/pH notes from their final anaerobic lot of the season were still fresh on the chalkboard.

When pressed (lightly, of course) for a backstory on the place’s name—Yellow Diamond Hacienda—Farm Manager Isaac smiled, assuring us it was merely meant to evoke something bright, rare, and valuable.

Country Context

Kenya is one of coffee’s great paradoxes. Its top coffees command some of the highest prices in specialty, yet farmgate compensations are some of the lowest, with national production declining for decades. Traceability to some degree is a given, but direct trade remains difficult. Farmers legally own coffee to export, yet have often been farther from customers than almost anywhere else. Internationally, Kenya reads as a land of microlots, but on the ground it runs on volume—AA and elephant beans—with the “microlot” impression largely an artifact of rigorous grading. And yet, for all of its antiquated or misunderstood attributes, it also possesses a thrilling frontier in the West.

In 2023, reforms upended many longstanding systems. Marketing agents—the only parties licensed to sell producers’ coffees at auction—were dissolved in favor of decentralized licensing. The Cooperative Bank’s Direct Settlement System sped payment straight to farmers. Most important, private export channels opened. For farmers, this shift was both liberating and bewildering. Many producers are cupping for the first time, experimenting with fermentation, trialing lot separations, and paying attention where they once didn’t.

As we continue calibrating to these evolving systems, we are building a service-based export model that turns traditional intermediaries into calibrated service providers. A network of cuppers, agronomists, millers, banks, and exporters supports each export. Producers submit samples on schedule; we evaluate, score, and price them against the week’s auction using a cost-plus framework. Accepted coffees move into secondary milling, bagging, and export—with shared visibility throughout.

Right now, in spite of its tremendous possibilities, we are still in the critical trial/error stage as far as achieving desired results. We are incredibly fortunate to have such strong partners on the ground, particularly out west, as we continue plowing forward together.
