Kiaguthu Factory is a washing station located in on the slopes of the Abedares mountain range in Neyri county. The station site sits at about 1800 meters above sea level, and acts as a collection site for member farmers in the surrounding hills to deliver their coffee for processing and export. Factories are effectively cooperatives, in that they're run by a member-appointed committee. Farmers in the region grow mainly Sl-28 and SL-34, with small amounts of Ruiru mixed in, and farms reach as high as 2000 meters above sea level. Kiaguthu is one of several coffees we picked up from Othaya Farmer's Cooperative Society (FCS), an FCS that includes an impressive amount of wet mills, 18 in all, dating back to the late 1950s. When the coffee is processed from cherry to bean, it is segregated by weekly, or even daily deliveries, in order to identify variants in quality. The separated batches are then run through screens in order to separate beans by size, the most common being AA (17-19 screen), AB (15-17 screen), and Peaberry. These are called "out-turns". This lot is an AA outturn, the largest of the bunch, and also commands the highest price.
