Origin
Kirinyaga Region, Kiambu Count, Kenya
Coffee reached Kenya in 1893, when French Holy Ghost missionaries planted Bourbon seed stock from Réunion, and by 1899 the same order had established coffee at St Austin's Mission on the edge of Nairobi, bordering what is now Kiambu. Kiambu quickly became one of the first centres of commercial estate coffee in the colony, and its farms remain among the country's most historic. The 1933 Coffee Act established the Coffee Board of Kenya and, from 1934, green coffee was sold through the Nairobi auction, a system that rewards quality with price, with reforms in recent years also allowing direct sales to buyers. Today Kenya's Central region, taking in Kiambu, Nyeri, Kirinyaga, Murang'a and Embu, produces the majority of the country's coffee. Kiambu is also home to the Coffee Research Institute at Ruiru, where the Ruiru 11 and Batian varieties were developed. Kenya's distinctive grading system sorts milled coffee by bean size and shape into AA, AB, PB, C and lower grades, so a C grade shares its origin and processing with the larger grades from the same lots. Kiambu's red volcanic soils, reliable rainfall and high elevations continue to produce some of Kenya's most recognisable cups.
