Duromina is a relatively new cooperative in the Jimma region of Ethiopia. The name roughly translates as “to improve their lives” in the Afan Oromo language.
Farmers cultivate their coffee in small homesteads and on hillsides under the shade of dense canopies provided by indigenous Acacia trees. There is no use of chemicals for their coffee, making it completely natural.

The wet mill sources most of its water from a nearby uncontaminated river, with their supply fed by gravity. Waste water from processing is treated through planted vetiver grass and two large dugout lagoons. The pulp created during processing is mixed with soil to create compost and can be used as fertiliser.
Technoserve
Before establishing the Duromina cooperative, farmers had to transport their coffee crops to a wetmill on the other side of a valley, crossing a river which regularly flooded in harvest season. The quality of the farmer's crops was greatly reduced due to delays reaching the mill, sometimes forcing them to sell their crop unprocessed and at greatly reduced prices.
Like Nano Chala, the Duromina cooperative is a success story for the not-for-profit organisation Technoserve, who helped secure the funding and training necessary for the wetmill in 2010.
This change meant farmers no longer needed transportation to reach a mill, or were forced to sell unprocessed beans for a lower price. Just a year later in 2011, Duromina’s coffee was voted the best coffee in all of Africa.
Soon major international coffee roasters came to the Duromina, meeting with coffee farmers and paying an premium of at least 65% over the international commodity price.
The farmers used this additional income to improve their homes, expand the local school, and build a bridge to connect their village with the larger communities and markets across the river: they’re bringing their whole community with them on the journey out of poverty

Our coffee philosophy
Our business approach
Fresh harvest coffee
We only source and roast coffee from each country’s latest harvest season (so the green coffee is never older than 1 year from the time of picking, processing and packing). This ensures the sensory qualities are always at their peak and unaffected by excessive ageing.
Roasted for espresso and filter (best enjoyed black)
Roast style: omni. Omni roasts are designed to brew and taste great both as espresso and filter. Our omni single origins generally sit on Agtron values in the ~70-60 value range. So, technically, they are somewhere in the lighter side of the medium spectrum.
Designed for espresso and filter brewing. Best enjoyed black.

Our roasting style and approach
Best brewed within days 15-49 post-roast
The ‘fresh is best’ saying doesn’t apply to coffee (contrary to popular belief). Waiting before opening and brewing your bag of whole coffee beans helps develop peak flavour and acidity.
But heads up: if you buy pre-ground coffee, brew it as soon as possible.
