Kenyan coffee is renowned for being some of the brightest in the world, and it’s no coincidence. One sip is enough to notice: lively acidity, dark red fruit, a background reminiscent of black tea, and a clean finish. In this article, we’ll tell you where that character comes from, what the letters and numbers on the label mean (SL28, SL34, AA), and how to brew it at home so it really shines.
Where Kenyan coffee is grown
Most Kenyan coffee is grown in the country's central highlands, on the slopes of Mount Kenya and the Aberdare Range. One of the most acclaimed regions is Nyeri, which is where the Kenyan coffee we roast in Barcelona comes from.
Three factors explain its quality:
- Altitude: coffee grows at about 1,500 to 2,000 meters. In the cool air, the cherry matures slowly and accumulates more sugars and acids.
- Volcanic soils: mineral-rich, they provide nutrients naturally.
- Two harvests per year: the main one at the end of the year, and a smaller one in the spring.
The varieties: SL28, SL34, Ruiru 11, and Batian
If Kenyan coffee tastes different, a good part of the credit goes to its varieties:
- SL28 and SL34: selected in the 1930s at Kenya’s Scott Laboratories (hence the "SL" initials). They are responsible for the classic Kenyan profile: bright acidity, great structure, and notes of blackcurrant and blackberry.
- Ruiru 11 and Batian: these are more modern and were developed to better resist diseases like coffee leaf rust and provide higher yields for the producer, without sacrificing cup quality.
Our batch combines all four varieties, as is standard in Kenya, blending the character of traditional varieties with the resilience of the new ones.
The Kenyan washed process and "factories"
In Kenya, most coffee is grown by smallholders. They don’t process it on their own farms; they take the freshly picked cherries to community washing stations, which are called factories. Our coffee is processed at the Mutwewathi station in Nyeri, at an altitude of 1,600 to 1,750 meters.
There, the cherries are hand-selected, depulped, and fermented in water to loosen the mucilage. Afterward, they are washed with clean water and dried slowly in the sun on African beds. This careful washed process results in the clean cup and sharp acidity typical of Kenya. If you want to see how flavor changes based on the process, we explain it in our article on natural vs. washed coffee.
What "AA" means in Kenyan coffee
In Kenya, coffee is classified by bean size. AA is the category for the largest beans, followed by AB, and it is not a grade of cup quality. Even so, large, uniform beans tend to roast more evenly, and AA batches are generally the most sought after. The batch we roast is AA screen size.
What Kenyan coffee tastes like
The tasting notes for our Kenya are blackberry, black tea, and citrus. In practice, this translates to:
- Bright and juicy acidity, which is more reminiscent of forest fruits than lemon.
- Silky body and a background reminiscent of black tea.
- Clean, long finish with no bitterness.
It is a coffee with personality, perfect for those who want to move beyond the classic profile of chocolate and nuts. If you're interested in understanding why each country tastes different, read our guide on what is single-origin coffee.
How to brew Kenyan coffee at home
Our Kenyan coffee is roasted for espresso, although it also works very well in an AeroPress. These parameters are a starting point: adjust the grind to your liking.
Espresso
- Dose: 18 g of finely ground coffee.
- Beverage: 38-40 g in the cup (approx. 1:2.1 ratio).
- Water: 93-94 °C.
- Time: 27-30 seconds.
If it turns out too acidic or sour, grind a little finer or slightly extend the extraction. Conversely, if you notice bitterness or dryness, do the opposite. To nail these adjustments, it really helps to have a grinder with fine adjustments like the Eureka Mignon Specialità and a machine with stable temperature like the Profitec Go 2.0.
With milk, the acidity of the Kenya turns into a very pleasant fruity touch in a flat white or a cortado.
AeroPress
- Dose: 15 g, medium-fine grind.
- Water: 220 g at 88-90 °C (since it's an espresso roast, a slightly lower temperature prevents bitterness).
- Time: stir, let steep for 1 minute, and press for about 30 seconds.
- Ratio: approx. 1:15.
An AeroPress Go Plus is ideal if you want to take the ritual on a trip or to the office.
Try Kenyan coffee and compare
The best way to understand an origin is to try it alongside others. You have several options:
- Buy Kenyan coffee in whole bean or ground for your brewing method.
- Daily Dose Pack: Kenya, Acevedo, and Brazil roasted for espresso, to compare acidity, balance, and body.
- Coffee Lab Pack: Kenya along with Ethiopia and El Salvador, three profiles and three different roasts.
