Ndumberi Coffee Farmers Co-op Society is quite close to the capital of Nairobi in the Kiambu growing area, a region dominated by large privately held estates (some owned by agribusiness multinationals). The presence of cooperatives in this landscape is a testament to Kenya_‹_s economic diversity, offering better options to farmers than other producing countries. And I must admit to the charm of any coffee which is phonetically called "Dumb Berry". The coop has three factories (coffee mills): Ndumberi, Ngaita and Riabai, and was formed in 1960, and was inaugurated by the founding father of independent Kenya, Jomo Kenyatta, a source of great pride for the coop. At the time the society had only one factory with 432 members. Today the society has 3 wet mills serving a membership of 2516 whose benefit extends to over 10,000 families. The average number of coffee trees per farmer is about 200; these are true small-holder farmers! This is one of the sweetest lots, with a balanced acidity, and depth as well. The dry fragrance has perfume-like floral qualities, rose-water and white cake. The wet aroma presents a darker palate of smells, with plum pudding, concord grape juice, and sweet milk chocolate being the most recognizable. In the cup there is juicy green grape married to the citric brightness (milder than other lots, which are more acidic overall). The cup is transparent, clean, and walks a delicate balance between bright fruited notes and refined sugar sweetness. There is a hint of rind, pepper, and tannic tightness in the finish, which adds a bracing accent to an overall juicy cup. As I cup this, Ndumberi lot, I keep thinking that it boils down to one essential cause/effect relationship (and this cane be said about these new crop Kenyas in general): this coffee makes me smile! And it is nice to remember my visit to the region a month ago, that the pleasant qualities of this coffee are a direct result of the work of the farmer, the coop, and the coffee mill.
