Nyeri County is one Kenya's most famous growing regions. Much of the coffee here is cultivated in the foothills of the Aberdare Mountains, which have warm days and cool nights and a plentiful water supply.
The name Nyeri is derived from the Masaai word nyiro, meaning red, after the red volcanic soil in the area. The name was adapted by white settler farmers to Nyeri. Most farmers in the area today grow tea and coffee as cash crops. Coffee varieties in the region are usually a mix between SL 28, SL 34 (roughly 80%) Batian and Ruiri 11.
Smallholders handpick ripe cherry and deliver it to the factory that day. At intake, cherry is meticulously sorted. All sorting is overseen by the cherry clerk, who ensures that only ripe, undamaged cherry Is received. Once sorted, cherry is pulped on the factory’s disc pulper and then density sorted. Pulped cherry is dry fermented for 16 to 24 hours. Skilled staff oversee fermentation, checking regularly to ensure fermented is halted at just the right moment. After fermentation, cherry is sent through washing and grading channels.
Kenyan coffees are classified by size. AB beans are those that are between screen size 15 and 18 meaning that beans are between 6 and 7 millimeters in size.
