Dumerso Sisters

The Dumerso Sisters produce coffee in the Yirgacheffe region of Ethiopia. Their coffees are cultivated at unspecified high altitudes within this well-known East African origin. The varietal landscape represented in the catalog consists entirely of traditional heirloom varieties. These cultivars form the genetic foundation for the washed coffees produced in this region. The process portfolio for the Dumerso Sisters focuses exclusively on the washed method across all recorded lots. This traditional processing technique highlights the clean profile typical of regional Ethiopian production. The catalog footprint for the Dumerso Sisters includes three total coffees, all of which are currently in stock. These lots are featured by a single roaster, Thom Bargen Coffee Roasters. Across their catalog entries, the coffees achieve an average Cherrybook Index of 51.2. Recent catalog examples feature single-origin and espresso offerings prepared via the washed process using heirloom varieties, all roasted by Thom Bargen Coffee Roasters. These include lots such as Dumerso Sisters Espresso and Ethiopia Dumerso Sisters. Overall, the work of the Dumerso Sisters in the index is characterized by a focused selection of washed heirloom coffees from Yirgacheffe offered through a single roasting partner.
