AA or AB, factory or blend, light or dark, 10 ounces or 12: a Kenyan coffee listing packs a lot into a few lines. Here is how to read one, and what five bags on sale today actually cost per cup.
Some brands we cover are clients of our publisher. What we recommend is decided by our editors, and prices are read on the date noted in each article. Our standards.
Quick take
- AA and AB are size grades, not flavor scores. AA is the largest screen size. One roaster describes AB as a notch less uniform with a bit more body.
- The “factory” is the washing station. A listing that names one tells you more than one that just says “Kenya.”
- Roast level changes what you taste more than anything else on the bag. Four of the five bags below are roasted light or moderate. One is roasted dark, which is unusual for Kenya.
- Bag sizes run from 8 to 12 ounces, so the shelf price is misleading. At 15 grams a cup, today’s bags cost between $1.01 and $2.25 per cup.
Why Kenyan coffee gets its own label vocabulary
Kenya is a small producer by volume. The USDA’s Foreign Agricultural Service forecasts 850,000 60-kilogram bags for the 2025/26 marketing year, and its report explains how that coffee is sold. Roughly 80 percent is marketed through producer co-operatives, and the Nairobi Coffee Exchange, running since 1935, handles more than 90 percent of sales. Licensed brokers grade and catalogue each lot before it goes to auction.
That’s why Kenyan bags are so specific: lots arrive already sorted by bean size and traced to a washing station, and roasters pass those labels on to you.
It’s also seasonal. Intelligentsia’s catalog feed lists 16 Kenyan coffees, and none of them was available the morning we checked. Seasonal lots sell out and rotate, so treat any bag below as available today, not indefinitely.
Editors’ note: We did not taste, brew, or lab-test any of these coffees. Everything below is taken from each roaster’s own product page, read on September 26, 2026, and the cost-per-cup figures are our arithmetic from the listed bag weight and price. Tasting notes are the roasters’ words, not ours. Health and nutrition claims made on any seller’s page were not verified and are not repeated here.
How we chose
We looked for Kenyan single-origin coffees that were in stock on the roaster’s own website today and priced per bag, not per subscription. Any product that was sold out or listed at a placeholder price was dropped. Then we recorded what each page publishes: grade, washing station or farm, varieties, process, elevation, roast level, and bag weight. Where a page leaves something out or contradicts itself, we say so. More in How we choose.
For cost per cup we used one dose for every bag: 15 grams of beans per mug, which is about 1 part coffee to 17 parts water for a 250-milliliter cup. That matches the ratio Stumptown prints in its own brewing guide. Brew stronger and every figure rises proportionally; the ranking holds.

The label, line by line
Grade: AA, AB, PB
Kenyan grades describe bean size. Coffee Research’s Kenya profile puts it simply: AA is the largest, followed by successively smaller grades. George Howell’s page for its Mamuto AB states that AB is “one grade lower than AA due to being less uniform” and suggests it gives a bigger body in the cup. A grade tells you how beans were sorted, not how the cup will taste.
Factory, farm, or blend
In Kenya a “factory” is the washing station where smallholders deliver their cherries. Stumptown names Karumandi and its co-operative. Onyx names Kamunyaka within the Iria-Ini Farmers Cooperative Society. George Howell names a single family farm. Verve does something different on purpose: Kubwa blends AA coffees from several producer groups across the central regions. A named station tells you provenance; a blend is built for consistency.
Variety
SL28 and SL34 come up constantly on Kenyan bags. Onyx’s page says SL28 was developed in the early 1930s by Scott Laboratories. Ruiru 11 and Batian are newer, disease-resistant cultivars. Several listed together, as on Onyx and Verve, is normal for smallholder lots.
Process
Most Kenyan coffee is washed, meaning the fruit is removed and the beans are fermented and rinsed before drying. Read this line carefully. If the story on a page and its spec block disagree, trust neither until you’ve asked the roaster.
Roast level
This is the line with the biggest effect on flavor, and roasters describe it in very different ways. Onyx gives a number (Agtron #127, which it calls “moderate”). Verve says “light roast.” Stumptown uses a slider with no number. Most specialty roasters keep Kenyan coffee light to preserve the fruit. If you drink dark, look at the one exception below.
Testing claims
“Mold tested” usually refers to ochratoxin A, a mycotoxin that can form on coffee. The European Union sets a legal maximum of 3.0 micrograms per kilogram for roasted beans and ground coffee (5.0 for instant). If a seller says its coffee is tested, the useful question is which lot was tested, by which lab, against which threshold. The answer should come as a certificate of analysis, not a badge.
Caffeine
Product-page caffeine figures are usually estimates. The steadier reference is the FDA, which cites 400 milligrams a day for most adults as an amount not generally associated with negative effects. The FDA describes that as about two to three 12-ounce cups of coffee, and notes that sensitivity varies widely.
Five Kenyan bags, read today
1. Verve Kenya Kubwa
$23 for 12 oz (340 g) · about 22 cups · $1.01 per cup
The cheapest per cup today, and the listing that tells you most clearly what it is. The Kubwa page calls it a regional blend of washed AA coffees from producer groups across Kenya’s central growing regions. It lists SL28, SL34, Ruiru 11 and Batian (spelled “Baitan” on the card), an elevation of 1,600 to 2,000 meters, and a light roast. Verve says each order is roasted to order and ships within two business days. Whole bean or three grinds, same price.
What it doesn’t say: no single washing station, which is the point of a blend.
2. Modern Roots Life Kenyan Origin
$23.99 for 12 oz (340 g) · about 22 cups · $1.06 per cup
The only dark roast in this group. That’s the reason to consider it: if you like a heavier roast and have skipped Kenyan coffee because every bag is light, this one is roasted dark. The Kenyan Origin listing describes a dark roast with citrus and floral notes and a lighter body, and comes as 12-oz whole bean, 12-oz ground (same price), or a 100-count K-Cup box at $69.99. It’s the one bag here sold as lab and mold tested. The company says certificates of analysis are available on request, with about a two-week turnaround. Ask for the one that matches your lot. The page also notes a current two-week ship time for the first batch. The coffee listing says shipping is free on all coffee orders, while the sitewide banner says free U.S. shipping over $100, so confirm at checkout. The same brand sells Colombian and Brazilian single origins in its lab-tested coffee range.
What it doesn’t say: grade, washing station, variety, process or elevation. On this page, “Kenya” is the whole origin story.
3. Stumptown Kenya Karumandi
$23 for 10.5 oz (298 g) · about 20 cups · $1.16 per cup
This page has the best processing story in the group. Stumptown’s Karumandi listing names the factory south of Mount Kenya and its co-operative (Baragwi, about 3,000 smallholders). It describes a wet fermentation of 17 to 30 hours with “no static times,” followed by raised-bed drying and final milling at the New Kenya Planters Cooperative Union. Its tasting notes are red currant, blackberry and dark chocolate.
What it doesn’t say: no grade, variety or elevation figure, and roast level is shown only as a slider. Note the 10.5-ounce bag. It costs the same as Verve’s 12 ounces.
4. Onyx Kenya Kamunyaka AA
$26 for 10 oz (283 g) · about 19 cups · $1.38 per cup
This page has the most data of the five, and it shows why you should read the whole thing. Onyx’s Kamunyaka page lists the AA grade, the Iria-Ini society, SL34/Batian/Ruiru 11/SL28, raised-bed drying, and a measured roast color (Agtron #127, “moderate”). A 2-oz sample is available for $7, which is a cheap way to try it. But the story text calls it “this natural lot” and “around 1,700 meters,” while the spec block says “Dry Washed” and 1,800 MASL. Those are different processes. Likely a copy slip, but ask before buying for the process.
What it doesn’t say: nothing is missing. Two lines just disagree with each other.
5. George Howell Mamuto AB
$34 for 8 oz (227 g) · about 15 cups · $2.25 per cup
The most expensive per cup by a wide margin, and the most traceable. The Mamuto AB page names the farm (the Mathagu family, 21 acres in Kirinyaga), the producer, washed processing, SL34 and heirloom varieties, 5,070 feet, and a December 2025 harvest. It’s the only page here with a harvest date. The roaster says it has bought Mamuto since 2006 and buys the farm’s entire crop. It’s sold as a light roast, whole bean or ground to one of four methods.
What it doesn’t say: little. The small 8-oz bag makes the shelf price look closer to the others than it is.
The bottom line
Read a Kenyan listing in this order: bag weight, roast level, then everything else. Weight tells you the real price. Roast level tells you whether you’ll like the cup. Grade, factory and variety tell you how much the roaster is willing to share. Four of today’s five bags roast light or moderate and publish a lot of origin detail. Modern Roots Life is the dark-roast option with lot testing available on request, but it publishes little origin detail. George Howell’s single-farm bag costs about twice as much per cup as the rest.
Prices, stock and roast details change often, especially with seasonal lots. We’ll correct anything that has changed; see our corrections policy.
