Wet Processing was introduced to Ethiopia in the 1970’s with the very first wet mill being in Yirgacheffe. Since then coffees have either been available washed or fully natural, and the movement into honey produced coffees is very new. The Kokie cooperative itself has 828 members, and joined with Yirgacheffe Coffee Farmers Cooperatives union in 2002 in order to increase their exposure to buyers and drive up the prices paid to them for their coffee. Local smallholders grow heirloom varietals known locally as Kumie,Diga and Wilsho. The genetic diversity in Ethiopia is loosely grouped into regional denominations for buying-Limu,Djimma,Sidamo,Yirgacheffe-with coffees recognized as having their own characteristics specific to each area.
