Specialty

Kenya Specialty Coffee

At its most typical: blackcurrant and tomato-leaf aromatics, high malic/citric acidity, dense body and a long, savoury-sweet finish.

Production is split between smallholder cooperative societies delivering to wet mills ("factories") and larger estates. Cooperative lots are usually sold by factory and outturn, which is what makes Kenyan traceability unusually granular.

What a specialty offer from this origin includes

Lot identity at the level shown above, the process detail the station records, moisture and water activity with the measurement methods stated, a screen analysis, a defect count, tasting notes, and a cupping score where the lot has been cupped — with the protocol named. We do not publish estimated scores.

Grades

Specialty grade designations

Grades used for Kenya specialty separations. They describe preparation and size — the cup is confirmed on the sample.

Kenya specialty grades
GradeWhat it encodesScreen
Kenya AAFlat beans retained on screen 17/18. The most quoted Kenyan grade — and the most frequently misread, because it describes size, not cup.Screen 17–18 (≈6.8–7.2 mm)
Kenya ABThe combined A (screen 16) and B (screen 15) separations, and normally the largest single block in an outturn.Screen 15–16 (≈6.0–6.8 mm)
Kenya PB (Peaberry)Single rounded seeds separated by shape from the main run. Denser per unit volume, so roast profiling differs.

Geography

Where specialty lots come from

Growing areas within Kenya, with the altitude and harvest timing that shape the separations available from each.

Kenya growing regions
RegionAltitudeHarvestCharacter
Nyeri1,600–2,000 mOctober–December, fly crop May–JulyRed volcanic soils between the Aberdares and Mount Kenya. Cooperative factories here produce many of the most structured and blackcurrant-driven Kenyan lots.
Kirinyaga1,400–1,900 mOctober–December, fly crop May–JulySouthern and eastern flanks of Mount Kenya. Dense factory network, frequently with very tight day-lot separations.
Murang’a1,350–1,800 mOctober–December, fly crop May–JulyLarge smallholder base south of Nyeri, generally rounder and less piercing than the higher Nyeri factories.
Embu & Meru1,300–1,950 mOctober–December, fly crop May–JulyEastern Mount Kenya. Meru in particular can be juicier and more tropical in profile than the classic central-highland cup.
Kiambu1,500–1,800 mOctober–December, fly crop May–JulyEstate-heavy area close to Nairobi, producing large, uniform single-estate lots.
Kisii, Bungoma & Trans-Nzoia1,500–1,900 mOctober–DecemberWestern Kenyan highlands. Smaller volumes, softer acidity, and generally more accessible pricing than the central highlands.
