What Does Washed Processing Do to Yirgacheffe?
Yirgacheffe is a small Ethiopian town at 1,700 to 2,100 meters, among the highest coffee-growing areas anywhere. The Rift Valley around Misty Valley stays foggy and mild, and Lake Turkana, Lake Abaya and Lake Chamo supply moisture. That setting produces the floral and fruity aroma the region is known for, and its washed lots are the most widely exported style.
In the fully washed method, skin, pulp and mucilage are removed through washing and fermentation. Farms need washing tanks and a steady flow of fresh water, and workers push the fermented beans repeatedly so friction and water current clean them. Coffee trees here grow scattered among forests, fields and courtyards, and the dried parchment is later milled, graded and exported under the Yirgacheffe name.

Front Street Coffee - Introduction to the Characteristics of Front Street Washed Yirgacheffe
Yirgacheffe is located in Ethiopia. It is a small town at an altitude of 1,700 to 2,100 meters and one of the highest coffee-growing regions in the world, having become almost a calling card for Ethiopian specialty coffee. Lake Turkana, Lake Abaya, and Lake Chamo together provide abundant moisture to this land. In the Rift Valley area centered on the Misty Valley, fog lingers year-round, the climate is mild like spring, and a gentle breeze blows, cool and humid. Thousands upon thousands of coffee trees grow luxuriantly here, creating the unique terroir charm of Front Street Yirgacheffe, where floral and fruity notes seem both near and far, interwoven and ever-changing.
The Historical Origins of Yirgacheffe
At first, the coffee trees of Front Street Yirgacheffe were introduced and planted by European monastic scholars (much like Belgian monks growing wheat to brew beer), and only later were they managed by farmers or cooperatives. The coffee trees are naturally scattered among forests, fields, and courtyards. During each harvest season, the Ethiopian coffee trading company goes to the town to purchase coffee beans from farmers, and ultimately auctions and exports them under the brand name "Yirgacheffe."
Fully Washed Method (Washed):
Through washing and fermentation, the skin, pulp, and mucilage are removed. Farms using the washed method must build washing tanks and be able to continuously introduce flowing fresh water. During processing, the fermented beans are placed into the tank and repeatedly pushed around; relying on friction between the beans and the force of the water flow, the coffee beans are washed until they are smooth and clean.
After washing is completed, the coffee beans are still wrapped in the parchment layer at this point, with a moisture content of about 50%. They must be dried to reduce the moisture content to 12%, otherwise the beans will continue to ferment and then become moldy and spoiled.
The more ideal processing method is sun drying. Although it takes 1 to 3 weeks, the flavor is exceptionally outstanding and highly favored by people.
