Origin of Potato Defect in Rwanda Coffee

Last year Aleco and I were traveling in Rwanda, and made a shocking discovery in the Western district of Nyamasheke. We found that potatoes were actually being processed along with coffee. (see photographic evidence) Hence all the research to find where the off taste of potato defect in coffees from the Lake Kivu area, and theories about antestia insect dame, fungus, and the chemicals generated from the response of the coffee plant itself to attack, they all are for naught. Remove the potatoes from the coffee processing system, and the potato defect will disappear! Why do people have to make everything so complicated. - Tom
