Are Kenyan Coffee Beans Expensive? What is the Best Coffee in Kenya?

FrontStreet Coffee Introduction - Kenyan Coffee

Kenya's coffee industry runs on confidence, and not only because of the country's vivid flavors — the intense aroma, the distinct fruit acidity. It's also because after harvest, all Kenyan coffee must be purchased uniformly through the government-established Coffee Board of Kenya (CBK), cupped, and graded. Grades are assigned by bean size, judged on size, shape, and weight. There are seven grades: PB, AA, AB, C, TT, T, and Buni. The top grade is AA (large beans retained on a 7.2mm screen), followed by A grade (second-largest, retained on a 6.8mm screen), B grade (medium, retained on a 6.2mm screen), C grade (all small beans below B), PB grade (oval-shaped peaberries), plus TT and T beans that are too light and too small. A and B beans are blended together for export as AB grade.

Kenyan Coffee Growing Regions

The seven most famous Kenyan growing regions are Thika, Kirinyaga, Mt. Kenya West, Nyeri, Kiambu, Ruiru, and Muranga.

Kirinyaga Region

Kirinyaga sits on the slopes of Mount Kenya next to Nyeri, and is famous worldwide for coffees of intense flavor, rich layering, and a solid mouthfeel. Together with Nyeri, it is recognized as one of Kenya's two finest growing regions. Most producers here are smallholder farmers organized into cooperatives, which act as the unifying layer — running the washing stations where farmers deliver their cherries to be processed into green beans.

SL28 and SL34 Varieties

As for the origin of SL28 and SL34: in 1930, Kenya's local Scott Laboratories set out to improve the coffee industry by working with local Kenyan varieties, hoping to cultivate plants with high yields, disease and pest resistance, greater adaptability to climate variation, and a fit for local soils. Researchers crossed traditional Kenyan natives such as Bourbon, Mocha, and Typica to create the two future stars, SL28 and SL34. Flavor-wise, they deliver a fruit acidity that surpasses traditional Bourbon, with pronounced notes of citrus, dark plum, and more.

Kenyan Washing Process (K72)

The Kenyan washed process uses repeated cycles of fermentation and washing. The finest cherries are selected on harvest day for depulping and a 24-hour fermentation. After 24 hours they are washed in clean river water, then fermented for another 24 hours in fresh river water, washed again — the cycle repeated 3 times to reach 72 hours total. Hence the name: the Kenyan 72-hour fermentation wash, or K72. This extended, cool-temperature fermentation gives the beans brighter, cleaner, yet fuller flavors!

Trading Methods

Model 1: Nairobi Coffee Exchange Auction

Since the auction system was established in the 1930s, the vast majority of Kenyan coffee has been sold this way. Auctions are held every Tuesday during the harvest season, and they evolved from an open-outcry format in which each trader bids by pressing an electric trigger. Thanks to competition among agents, prices for high-quality, sought-after lots can soar.

Model 2: Direct Trade

Direct trade lets farmers and buyers (roasters or importers) agree on a price different from the auction, either before or during the harvest. Some exporters also buy directly from marketing agents or factories, using the previous week's auction prices for a given grade as their negotiating reference. Direct trade can mean meaningfully higher income for farmers producing top-quality coffee.

FrontStreet Coffee Recommendation

If you want to taste what makes Kenya special, FrontStreet Coffee recommends starting with a top-grade light roast:

FrontStreet Kenya Cherry Tomato (AA TOP) — a premium washed Kenyan from the Thika region, grown at 1,550–1,750 meters on the classic SL28 and SL34 varieties, with full, round beans meeting the AA TOP standard. Processed with Kenya's signature 72-hour double fermentation wash (K72) to amplify the fruit while keeping the cup clean, and roasted light to preserve its lively acidity, it offers dried cherry tomato and floral notes in the dry aroma, then vivid cherry tomato and dark plum flavors with bright, juice-like acidity. The mid-palate brings sweetness of snow pear and black plum, finishing long and clean with yellow sugar and a whisper of green tea. Balanced, distinctive, and unmistakably Kenyan — our top pick for anyone exploring this origin, especially brewed as a pour-over at a medium-fine grind with 91–92°C water.
