The Coffee
A new arrival from the highlands of Yirgacheffe, Ethiopia Dumerso offers a cup of exceptional brightness and clarity. Grown at altitudes of 1,800 to 2,000 metres by over 750 smallholder farmers, this washed heirloom coffee is processed at the Dumerso Washing Station — brought back to life in 2013 by sisters Hirut and Mahder Birhanu.
The cherries are grown in mineral-rich red clay soil, shaded by native Acacia, Birbirra and Wanza trees. After hand-sorting, they are pulped and fermented for up to 48 hours before being dried slowly on raised beds for up to 15 days.
With zesty notes of lemon and lime softened by pineapple, black tea and delicate florals, this light roast is a vibrant expression of its origin.
The Birhanu sisters also lead a sustainability initiative at the washing station, turning discarded coffee parchment into pressed firewood — helping to reduce reliance on gathered wood and protect the surrounding forest.
Best enjoyed black to appreciate its delicate profile. We recommend brewing as a filter or pour over using 15–16g of coffee per 250ml of water.
