Kenya Coffee

Kenya's coffee industry is relatively young by African standards. Unlike Ethiopia, where wild arabica grows natively, Kenya did not have coffee cultivation before the late 19th century. Arabica was introduced by Scottish missionaries in 1893, and commercial cultivation followed during the British colonial period in the early 20th century. The first Kenyan coffee was exported in 1908.

The colonial-era agricultural research that defined Kenya's modern coffee identity happened at Scott Agricultural Laboratories (now KARI — Kenya Agricultural Research Institute). In the 1930s–1950s, researchers at Scott Labs developed SL28 and SL34 — selections from trees showing drought and disease resistance. SL28 is believed to be related to a Tanzanian varietal introduced from South America via Tanganyika; SL34 comes from a different genetic line. Both produce the high-acid, intensely fruited cup that Kenya is now famous for.

The Nairobi Coffee Exchange (NCE) auction system is the other defining feature of Kenyan coffee. Coffee farmers deliver cherry to cooperative-owned washing stations (called "factories" in Kenya), which process the coffee and submit it to the NCE auction. The traceability is at the cooperative/factory level — a bag labelled "Kii AA, New Ngariama Cooperative" is traceable to a specific factory and cooperative, though not to an individual farmer's plot. This system creates quality competition: better cup scores mean higher auction prices, which benefits the cooperative and its members.

Kenya produces two crops per year — the main crop (October–December, the larger and more important) and the fly crop (April–June, smaller, often lower altitude). Specialty buyers focus almost exclusively on main crop lots.

The current challenge for Kenyan specialty is price. NCE auction prices for top lots have risen significantly as international specialty demand has grown, making Kenyan AA expensive relative to Colombian or Ethiopian at comparable quality levels. The flip side is that traceability has improved: more roasters are buying directly from cooperatives, bypassing the auction where possible, which increases the quality floor on what reaches UK shelves.
