Every Tuesday, Dirk Sickmueller, General Manager of premier export company Taylor Winch (Coffee) in Nairobi, goes to auction. Rather than a vision of excited bankers yelling out figures and gesticulating wildly like a scene from The Wolf of Wall Street, green bean buyers and local roasters bunker down in a theatre-style auction hall. The scene appears more subdued thanks to the digital platform the Nairobi Coffee Exchange implemented 20 years back, which only a few months ago had an upgrade to include a web camera and TV screens so that farmers in certain coffee growing regions can watch the bidding action unfold. Prices are displayed on a large digital screen. The numbers fly back and forth, with the final print, or best bid, confirmed or noted to a particular buyer.
