Kiambu county sits adjacent to Nairobi, Kenya’s capital city, and is a coffee powerhouse. Along with an extensive community of coffee mills, exporter warehouses and quality labs, the Kenya Coffee College and Coffee Research Institute (near Ruiru Town, after which the disease-resistant hybrid is named), Kiambu is also home to many of Kenya’s largest and oldest coffee estates. Because of its proximity to Nairobi, Kiambu is urbanizing quickly. Ruiru Town is Kenya’s 6th largest urban municipality and if development continues the way it has, many expect a majority-urban county in just a few years. Yet Kiambu continues to be home to a number of well established cooperative societies, such as Ndumberi FCS. Kenya’s coffee is dominated by a cooperative system of production, whose members vote on representation, marketing and milling contracts for their coffee, as well as profit allocation. The Ndumberi processing station, or “factory” as it’s known in Kenya, has over 2600 contributing farmer members, who in addition to coffee typically also grow banana and corn, with grevillea or macadamia trees planted for shade and nutrition. Kenya is of course known for some of the most meticulous at-scale washed processing that can be found anywhere in the world. Bright white parchment, nearly perfectly sorted by density and bulk conditioned at high elevations is the norm, and a matter of pride, even for generations of Kenyan processing managers who often prefer drinking Kenya’s tea (abundantly farmed in Kiambu and nearby Muranga county) to its coffee. Cherry is delivered each day to the Ndumberi factory by participating members, cherries are sorted for ripeness, then depulped and fermented overnight. Once fermentation is complete it is washed with freshwater in long channels and sorted by density into “P1” (the highest quality), “P2”, “P3”, and “P light”. Each density grade is dried individually on raised beds between 14 and 21 days and stored separately for conditioning on the factory property. “48KF0015” in the title refers to this coffee’s “outturn” number. Outturn numbers are unique microlot codes that are given to each and every batch of parchment delivered to dry mills from individual factories or estates anywhere in Kenya, and are the units on which Kenya’s entire microlot export system is built. Outturns in Kenya are tracked with a shorthand code that places the specific batch of parchment coffee in time, place, and sequentially with other coffees. Outturns are stylized as an 8 or 9-character code, including a 2-digit “coffee week” number, a 2-letter mill code, and a 3 or 4-digit intake number for the coffee’s delivery. So this particular lot was delivered in harvest week 48, to the Kofinaf dry mill (code “KF”), and was the 15th delivery that week. This particular lot comes from Ndumberi’s “fly crop”, a smaller secondary harvest common in many equatorial coffee producing countries that follows a secondary rainy season. Fly crop Kenyas are not as large or sought-after as the main harvest, but nonetheless can yield exquisite tasting coffee. High FOB prices for great Kenyas, while the norm, are not a panacea, and in Kenya in particular the number of individual margins sliced off an export price before payment reaches the actual farms is many, leaving only a small percentage to support coffee farms themselves, and most often this arrives many months after harvest. However, Kenya coffees are sold competitively by quality, which means well-endowed counties like Kiambu achieve very high average prices year after year. As a result, the majority of the smallholders here, with a few hundred trees at the most, along with additional employment or land uses in the highlands, are generally considered to be middle class.
