FrontStreet Coffee - Kenyan Premium Coffee Introduction

Kenya lies in eastern Africa, with the equator running through its central region and the Great Rift Valley extending from north to south. It borders Somalia to the east, Tanzania to the south, Uganda to the west, and Ethiopia and Sudan to the north, with the Indian Ocean to the southeast.

Kenyan coffee, known as the "Connoisseurs' Cup," is characterized by a rich aroma, bright and lively acidity, a full and elegant body, and a multi-layered mouthfeel with juicy acidity that leaves a lasting impression.

Most Kenyan coffee grows at altitudes between 1,500-2,100 meters, with two harvests a year. Coffee from different regions tastes distinctly different because of variations in microclimate. Kenya's production is best known for its seven major regions: Thika, Kirinyaga, Mt. Kenya West, Nyeri, Kiambu, Ruiri and Muranga. The foothills of Mt. Kenya and the Aberdare range are the primary producing areas.

Today, FrontStreet Coffee would like to share a Kenyan coffee from the central region of KIAMBU (Kiambu), specifically from the Kamvara Mandela processing plant. This coffee grows at an altitude of 1,720 meters, is of the SL28 and SL34 varieties, and is processed by the washed method.

Central Region - KIAMBU

The central KIAMBU (Kiambu) region is a traditional tea-growing area in Kenya, but it also contains the highest altitude coffee-growing zones in the region. The area is named after Nakuru town, and coffee grows at altitudes around 1,850-2,200 meters. Coffee production here is relatively limited and follows a plantation and smallholder model, with two harvest seasons a year.

The Mandela processing plant, located within KIAMBU, is a small farm operation of nearly 30 hectares growing SL28 and SL34 varieties at altitudes between 1,600-1,800 meters.

SL34 & SL28

These two varieties were selected and cultivated in Kenya by French and British missionaries and researchers in the early 20th century. SL-28 derives from the Bourbon variety and offers ample sweetness, balance and complex, varied flavors with distinctive citrus and dark plum characteristics. SL-34 originates from Typica and features complex acidity, wonderful sweetness and a smooth, clean mouthfeel.

K72 Washed Processing Method

Washed processing begins by selecting the highest-quality cherries for pulping and fermentation. Fermentation lasts 24 hours, followed by washing. The coffee then undergoes another 24 hours of fermentation in clean water, followed by another wash. The cycle repeats three times, totalling 72 hours, which is why it is called the Kenyan-style 72-hour fermentation washed method, abbreviated K72.

FrontStreet Coffee Recommendation

Ethiopia is a benchmark specialty origin and, as coffee's birthplace, it holds an enormous number of native varieties, which makes it a treasure house for drinkers who want to follow a flavor faithfully. FrontStreet Coffee's washed Yirgacheffe is the entry-level starting point: it shows clear jasmine florals and bright citrus acidity, and Yirgacheffe itself is a small town in southern Ethiopia that is spring-like all year, misty and cool, where thousands of coffee trees flourish and give the cup its interwoven florals and fruit acidity, a light, elegant, tea-like drink that tastes like clean lemon tea.

Ethiopian coffee is mostly grown in a garden-farming pattern, where each smallholder sends the harvested cherries to a village-level processing station and the coffee is then sold under the producing team's name, which is why we see cooperatives of all sizes such as FrontStreet Coffee's Gutingtin, Worka and Konga. Gutingtin sits in the Worka district at the southeastern edge of Yirgacheffe and was originally part of the Worka cooperative under the Yirgacheffe Coffee Farmers' Cooperative Union (YCFCU). As buyers pushed for traceability in green beans, independent single-origin lots were dug out one by one, and in 2012 Gutingtin, with roughly 300 member farmers, became a cooperative in its own right. Because the fruit is stripped before drying, Gutingtin's inherent aroma comes through more clearly, showing citrus and lemon notes and elegant white florals, bright and fine overall. Natural processing takes the opposite route: damaged or mouldy fruit is removed first, then the cherries dry in the sun for two weeks until the sugars and essence of the fruit have seeped into the bean and moisture falls to 12%, after which the hardened fruit, mucilage and parchment are scraped off by machine, and the beans are checked for density and color, sorted for defects and finally hand-picked by workers for anything the machines missed. The layers of sorting are why the beans are consistently high quality, clean and unusually aromatic; FrontStreet Coffee's Yirgacheffe Natural Red Cherry shows peach, cocoa, honey and lemon.

Beyond Yirgacheffe, FrontStreet Coffee's Sidamo Huakui comes from the Hambella district of Guji in Sidamo, where the farm covers 200 hectares and uses a traditional natural process. To keep the drying fruit from moulding or picking up soil taints, workers spread ripe cherries on raised beds for 21 days, turning them constantly for even drying and removing mouldy or defective beans by hand every three to five days; once the skin has dried hard, a huller removes it, and the growers do a final sorting pass after the green beans are obtained. Because the fruit and skin stay on through the whole dry, a medium-light roast gives light fermented wine, florals, citrus and mango with a richer, more complex body, honey sweetness, a cocoa note and a hint of spice, with a full body and a lasting finish. FrontStreet's Sidamo Natural Hamasho comes from the same region, and the Hamasho station has become a regular on Ethiopian green bean competition lists thanks to its quality and distinctive flavor. Its coffee is mainly the disease-resistant 74 series released by the Jimma Agricultural Research Center (JARC), and the 74158 line has smaller beans with prominent floral and fruit aromas: perfume lemon, strawberry and star fruit on the nose, then clear strawberry, star fruit and green grape sweetness in the mouth, with florals gradually emerging. Finally, FrontStreet Coffee's Kaffa Forest comes from a very different model. Rather than garden farming, Kaffa is known for wild coffee, with trees growing in shade at 1400-2100 meters where the untouched ecosystem, microclimate, red soil and plentiful rainfall create excellent conditions. Roasted medium-light, it is distinctly floral once ground, with bright lemon acidity and sweet orange and bergamot in the mouth, a melon-and-nut sweetness in the finish and a green-tea-like body.
