FrontStreet Coffee - African Coffee Origins: Kenya's Coffee Growing Regions

Kenya is a model country for producing excellent coffee. The high-altitude, washed Arabica beans grown there rank among the finest in the world. Coffee was introduced from Ethiopia by the British in 1900, and today it forms the largest sector of the agricultural economy, accounting for roughly 50% of the total. About 80% of the population works in coffee-related industries. Since 1963, most Kenyan coffee beans have been uniformly graded and inspected by the Kenya Coffee Board before being sold at auction.

AA grade covers all beans sized 17-18 on the screen, while AB grade covers beans sized 15-16, with up to 10% allowed below 15. Grade alone, however, does not correlate directly with actual quality. The Kenya Coffee Board maintains very strict standards for research, development, and quality management. Its outstanding auction system lifts bean prices and, in turn, indirectly helps hardworking farmers, while agricultural education keeps cultivation techniques continuously updated and improved. High-quality Kenyan coffee, with its distinctive, powerful blackberry-like fruit acidity, is produced in limited quantities; these lots are the estates that green bean merchants compete to acquire.

A coffee bean usually consists of two pea-shaped seeds (often called female beans). Peaberries (PB), by contrast, grow as a single round or oval seed (often called a male bean). Kenyan peaberries are a hand-selected variant of Kenyan beans. Among all coffee peaberries they have the most distinctive character, the widest roasting range, and the most unique variation, which is why they are so familiar to coffee lovers.

Thika Region

The Asali Cooperative AA Top is produced in the foothills of the Aberdare Mountains, in Kenya's Thika region near the eastern Great Rift Valley that borders Ethiopia. The cooperative is made up of 155 smallholder coffee families who own the washing station, with an annual production of 1,200 bags of green coffee. The coffee comes entirely from nearby smallholders' cultivated plots. On average, each farmer grows 250 coffee trees and delivers harvested red cherries to the washing station for processing. Coffee from this region is prized for its blackcurrant aroma and flavor. Flavor description: grapefruit aroma, mulberry, caramel, a candied sweet-and-sour sensation, full-bodied and juicy, crisp and sweet.

Widely planted varieties include Bourbon, Kents (SL34, SL28), Typica, and Riuri 11. Today about 90% of cultivated coffee is SL34 and SL28. The new variety Batian, released in 2007, has yet to be widely planted. The vast majority of Kenyan coffee is organically grown without certification, because improved cultivation techniques keep the use of chemical pesticides and herbicides to a minimum. All premium Kenyan coffee is washed. Sun-dried, unwashed beans (M'buni) are low-grade and intended only for the local market.

Knowledge Extension

Full-bodied AA beans are round and thick-fleshed, with excellent heat conductivity, rich flavor, and good expansion; both their aroma and sweetness are of superior quality. Beans of this grade are often considered by many to be among the best coffee in the world.

FrontStreet Coffee Recommendation

If Kenya's blackberry-and-grapefruit profile is what draws you to African coffee, the natural next step is Ethiopia, where the continent's coffee story began. FrontStreet Coffee's washed Yirgacheffe is the classic entry point: a clear jasmine florality lifted by bright citrus acidity, light and elegant on the palate with a tea-like finish that recalls a clean, refreshing lemon tea.

For a fuller picture of Ethiopian terroir, try FrontStreet's Yirgacheffe natural Red Cherry, with its peach, cocoa, honey, and lemon notes, or the Guji Hambella natural Hana Asako, a traditional sun-dried lot spread on raised beds for 21 days that opens with soft fermented wine, floral, citrus, and mango tones before deepening into honeyed sweetness, a cocoa bass note, and a long, full body. Together they trace the same fruit-forward African signature that makes Kenya so compelling.
