Anasola Washing Station is located in the Anasola settlement at an altitude of 1900m in Shakiso County, northwest of Guji. Coffee is mainly produced in five districts in Guji: Uraga, Adora, Shakiso, Hambela, and Kercha. Shakiso is known as one of the richest areas in Ethiopia, where coffee is produced in the forest belt nurtured by fertile volcanic soil. During the harvest season, cherries are brought in every day by over 300 small-scale producers living in the surrounding area. Anasola Washing Station aims to produce high-quality coffee of Grade 1 standard, and only cherries with good ripeness are selected by selecting again. In the anaerobic slow drying process, carefully selected cherries are anaerobic fermented in temperature-controlled sealed bags, and are slowly agitated on African beds for about 2 to 3 weeks to achieve the ideal moisture value. Thanks to the rich volcanic soil, the unique natural environment, the microclimate due to the complex topography of elevation, and the temperature difference between day and night, the cherries gradually ripen, and the coffee has an exotic and unique flavor that is unique to Guji. Since Guji was categorized as a coffee producing area, the motivation of the washing stations and producers has increased, bringing vitality to the region.
