What’s new

Duromina formed a new union, Kata Muduga Union, with other Western Oromia Co-ops, including the Nano Challa Co-op. They hope the new union will represent their collective interests better while furthering their dedication to high quality coffee.

The Producer

Duromina Cooperative sits in the yellowed highlands of the Goma District in the Oromia Region of Western Ethiopia. Farmers cultivate coffee in small plots near their homes and on densely shaded hillsides. Coffee has been cultivated here for generations, but prior to 2011, it was all dry processed and sold to local traders at a low rate.

Duromina, which means ‘improve their lives’ in the Afan Oromo language, was formed in 2010 by farmers who wanted to do just that. Immediately thereafter, they received a loan from the bank, constructed a wet mill, and began processing washed coffee. From Stumptown's purchases in 2011, Duromina paid off their entire washing station loan in just one year, rather than the anticipated four years.


The Place

It’s a 30-hour trip to get to the remote Agaro district of the Jimma zone. A six hour van ride through lush green mountains ends at the village, where our Coffee Sourcing team often enjoys traditional Ethiopian feasts of goat. The soil there is a bright red-orange and stains everything. One of our sourcing team members reports that after he got back, he washed his black t-shirt twice, and it’s still just as orange as when they left the village.


The Process

Duromina attracts new members with competitive pricing while keeping sustainability at the forefront. In 2016, Duromina installed a new type of demucilager, the first of its kind in Ethiopia, that creates a smaller ecological footprint by using up to 3/4 less water than their current setup. After coffee cherries are depulped, coffee is then soaked overnight and the clean parchment is dried in the sun for 7-10 days. Duromina built a second washing station and expanded their cherry collection sites in 2013, then added a third washing station in 2016 with an even lower water impact. They divert the water used at their washing stations through a filtering area before it returns to the river.


More Details

Duromina also invests in their community. The village used to be inaccessible during the rainy season, so the co-op worked with the government to co-fund a road project and built a bridge to give them year-round access. They also expanded the primary school up to 8th grade to strengthen education and are also constructing a health clinic. A dual purpose school bus was purchased to bring their kids to school and provide a way to move coffee cherry from collection sites to the wet mills. Families can now afford to send their children to secondary school in a nearby town. Farmers have improved their homes with new roofs, furniture, and solar power.
