Kenya AA is sourced from the Kenyan open auction system, which is part of the Nairobi Coffee Exchange. The quality of coffee and transparency in access has allowed for strong prices relative to other origins. Most coffee is grown in the hills surrounding Mount Kenya, where the rich soil helps produce high quality coffee. Farmer plots are exceptionally small and are generally classified by number of trees in production rather than the physical area of the farm. This allows farmers to exercise significant control over the coffee picked and delivered to the local wet mill. These mills have an abundance of water, which allows for the high-end washing methods that showcase the hallmark Kenyan profile.
