Origin
Machakos County, Kenya
Coffee arrived in Kenya with French Holy Ghost missionaries near Bura in 1893, but commercial production took off in the early 1900s under British settler estates; African smallholders were only permitted to grow coffee from the 1930s–50s onward, and it was this later smallholder expansion – organised through farmer co-operative societies and their communal "factories" (wet mills) – that now forms the backbone of Kenyan production. Kenya uses a distinctive screen-size grading system (E, then AA as the largest commercial grade, down through AB, C, PB for peaberry, and lower grades TT/T), with most quality lots sold through the weekly Nairobi Coffee Exchange auction, alongside a growing direct-trade and second-window system.
The country's high-altitude volcanic soils, dual bimodal rainfall (main crop October–February, fly crop May–August) and heirloom SL varieties combine to produce the intensely juicy, blackcurrant- and citrus-toned acidity that defines the "classic Kenyan cup." Kenya's meticulous washed processing – full pulping, multi-stage fermentation, repeated washing and slow raised-bed drying – is widely regarded as one of the most rigorous in the coffee world and a major contributor to the clarity and brightness for which its coffees are known.
