Kenyan Coffee: Blackcurrant, SL28 and the AA Grade
Key takeaways
Blackcurrant is on 22% of the 541 single-origin Kenyan coffees in stock, against about 1% of every other coffee on Cuppd.
SL28 is listed on 77% of Kenyan lots, but most are field blends: 305 lots list SL28 or SL34 alongside Ruiru 11 or Batian.
AA, AB and PB are bean sizes, not quality scores; AA appears in the name of 157 lots, AB in 40 and PB in 35.
86% of Kenyan lots are washed, and Kirinyaga (136 lots) and Nyeri (130) supply half the shelf.

Which Kenyan region has the best coffee?
There is a moment the first time someone hands you a good Kenyan. You taste it, you pause, and you say 'that's blackcurrant' out loud, to nobody. Nobody told you to expect blackcurrant. It is just there.
It is not your imagination, and it is not the roaster's. Of the 541 single-origin Kenyan coffees in stock on Cuppd, 22% list blackcurrant as a tasting note. Across the other 13,249 coffees on the site, it is about 1%. No other country has a flavour that much its own. Here is why it tastes like that, what AA and SL28 on the bag mean, and which lots to start with.

What does Kenyan coffee taste like?
Blackcurrant first, then sharp fruit. After blackcurrant (22% of lots) come blackberry (13%), grapefruit (12%), floral, caramel, raspberry, plum and cherry. Roasters used 179 different notes across all Kenyan lots, but the vocabulary keeps circling back to dark berries, citrus peel and a savoury tang — rhubarb, redcurrant, even tomato on the wilder bags.
The acidity is the other half. A good Kenyan is very bright and very juicy at the same time; a bad one is just sour. When it is right it tastes like fruit juice that happens to be hot. When it is under-extracted it tastes like a lecture.
Acidity: the bright, mouth-watering quality in coffee, like the snap of a ripe berry. It is a flavour, not a stomach problem, and Kenya has more of it than almost anywhere.
Processing shifts the flavour more than people expect. Blackcurrant is on 23% of the 467 washed Kenyans but only 13% of the 39 naturals, and the naturals pick up chocolate instead: 31% of them list a chocolate note, against 16% of washed lots. If you want the Kenyan cliché, buy washed.
Washed — blackcurrant, grapefruit, redcurrant
Why does Kenyan coffee taste like blackcurrant?
Nobody has a single proven answer, but the usual suspects all point the same way: high-grown coffee on volcanic soil around Mount Kenya, a strict washing process, and a handful of varieties selected for this country. The catalogue lets us check one of those.
Start with the varieties. SL28 is listed on 418 of the 541 Kenyan lots (77%), and its sister selection SL34 on 334. Both were picked out by Scott Agricultural Laboratories in the 1930s, are prized for their cup, and are badly exposed to leaf rust and coffee berry disease. So Kenya bred its own resistant varieties: Ruiru 11, released in 1985, and Batian in 2010, named after Mount Kenya's highest peak and bred partly from SL28 and SL34. They are on 286 and 237 lots.
Here is the part that surprises people: most Kenyan lots are all four together. Farmers grow them side by side and the factory processes them as one, so 305 lots list SL28 or SL34 alongside Ruiru 11 or Batian, and 151 list all four. Only 23 are pure SL28. And the mixed lots carry blackcurrant at least as often as the SL-only ones — 24% against 18% — so the resistant varieties are not the flavour-killers their reputation suggests. Only 16 lots are Ruiru 11 or Batian without either SL; two of them list blackcurrant.

How is Kenyan coffee processed and graded?
Washed, often soaked, then sorted by bean size — and AA, AB and PB on the bag are those sizes, nothing else. After milling, the beans go through screens: AA is the largest, AB the next size down, PB is peaberry, and there are smaller grades below. Nothing in the letters measures flavour. 157 Kenyan lots in stock carry AA in their name, 40 carry AB and 35 carry PB; the rest name only the factory.
Peaberry (PB): a cherry that grows one small, round seed instead of the usual two flat ones. It is sorted out and sold as its own lot.
Bigger beans tend to come from healthier trees and fetch higher bids, so AA has become a shorthand for 'the good stuff'. But an AB from the same factory and the same week is often just as good, and roasters know it. If a roaster you trust is selling a well-described AB, buy the AB.
The grading is the last step of a famously careful process. Most Kenyan coffee is grown by smallholders who belong to cooperatives, and the cooperatives run the 'factories' — the local word for a washing station. Cherry is pulped, fermented, washed in channels, and then often soaked under clean water before drying. The FAO describes a soak of about 12 hours after fermentation as improving both colour and taste.
Factory: Kenyan for a washing station, usually owned by a farmers' cooperative society. It is why bags say Gachatha, Kii or Kamwangi rather than a farmer's name.
It shows in the shelf. 467 of the 541 single-origin Kenyan lots (86%) are washed, and only 39 are natural. That is the opposite of Ethiopia, which splits evenly. Most Kenyan coffee is then sold through a weekly auction at the Nairobi Coffee Exchange, where roasters and importers bid on individual factory lots; a 'second window' for direct sales has existed since 2007-08, but the auction still handles most of the crop.
The rarer side — Kenyan naturals
Which Kenyan coffee regions should you know?
Two counties on the slopes of Mount Kenya supply half the shelf. Of the lots with a region on the label, 136 come from Kirinyaga and 130 from Nyeri, and they are also among the most blackcurrant-heavy.
- Kirinyaga: the current roaster favourite and the deepest shelf. Blackcurrant on 27% of its lots. Factory names to look for include Kii, Kamwangi and Karimikui.
- Nyeri: the classic, with red volcanic soil and blackcurrant on 26% of lots. Gachatha and Gatomboya are regulars.
- Kiambu: near Nairobi, more estate country than smallholder plots. 64 lots, and noticeably softer: blackcurrant on 13%.
- Murang'a, Embu and Meru: smaller volumes (34, 20 and 6 lots), often rounder and sweeter, and a good entry point if full-strength Kirinyaga feels like a lot.
- Nandi: west of the Rift Valley and far from the Mount Kenya cliché. Only 11 lots, but 6 of them are Batian or Ruiru 11 without either SL, 6 of the 16 such lots on the shelf.
Which roasters sell the most Kenyan coffee?
Kenya is a one-bag origin for most shops. Of the 325 roasters with a single-origin Kenyan in stock, 225 have exactly one, and only 15 carry five or more. The top two, Five Senses in Perth (14 lots) and Goriffee Roastery in Bratislava (12), hold 26 — about 5% of the shelf.
Each of the top three does Kenya differently. Five Senses spreads 14 lots across eight counties, from Kirinyaga to Nandi, Meru and Nakuru, with two double-fermented lots. Goriffee mixes washed AA, AB and PB with naturals from Kiambu and Nandi. Cafés San Agustín in León (10) stays on Mount Kenya and lets you compare its counties: three lots each from Kirinyaga, Nyeri and Embu, plus a natural from Kiambu.
How should you buy and brew Kenyan coffee?
Get a washed lot from Kirinyaga or Nyeri, AA or AB, whichever the roaster describes better. Brew it as pour-over and let it cool for five minutes before you judge it; Kenya opens up as it cools and the blackcurrant fully arrives.
It punishes under-extraction harder than almost any other origin. Grind a touch finer than you think, use water that is genuinely hot, and give it time. As espresso it is a wild ride; as filter it is the whole point. And if Kenya turns out to be too sharp for you, try Ethiopia's softer, more floral style instead.

How did we count 541 Kenyan coffees?
Every number on this page is a count from the Cuppd catalogue, not an estimate or an export statistic. Specifically:
- Source: the product listings on 940 specialty roasters' own online shops, not marketplaces or resellers. A coffee counts once per roaster; Onyx Coffee Lab's US and EU shops are counted as one roaster.
- In stock: every coffee is re-checked against the roaster's shop once a month. All figures here are for lots confirmed available on 2 October 2026.
- Origin: as the roaster labels it. 653 coffees in stock contain Kenyan beans; 541 are single-origin Kenyans, and every share on this page uses those 541. The other 112 are blends and multi-origin lots.
- Varieties, grades and regions: varieties as the roaster lists them (89 lots name none). AA, AB and PB are counted from the coffee's name, so lots that print the grade only in the description are missed. Regions come from the roaster's county tags, grouped by county; lots with no region are not in the regional figures.
- Tasting notes: the roaster's own notes, mapped onto a shared vocabulary of 330 notes so spelling variants of the same note count as one. A lot can list several, so shares do not add up to 100%.
- Not ranked: nothing here is scored or sponsored. Roasters are ordered by how many Kenyan lots they stock, nothing else.
