Why Are African Coffee Beans Sour? The Clean, Clear Taste and Sweet Aftertaste of Washed Yirgacheffe

FrontStreet Coffee's Introduction to Yirgacheffe Coffee

Africa is the third largest continent in global coffee production, following Central and South America and Asia. Africa's premium beans mainly come from Ethiopia, Kenya, and Yemen. Ethiopia is the largest Arabica-producing country in Africa. Yemen, located at the southern tip of the Arabian Peninsula and facing Ethiopia across the Gulf of Aden, although geographically part of West Asia, has historically been classified as part of the African coffee region.

Ethiopia is one of the main producers of Arabica coffee in Africa and is widely recognized as the birthplace of coffee. Ethiopia's native Heirloom variety, as an ancient, high-quality coffee variety, consistently expresses unique characteristics across various Ethiopian growing regions. Arabica species were likely first discovered in southern Sudan, but it wasn't until they spread to Ethiopia that they began to flourish. People there started consuming coffee fruits, initially as fruits rather than beverages. Yemen was the first country to cultivate coffee trees as plants, but Ethiopia had been harvesting wild coffee fruits even earlier.

Ethiopia's geographical environment is highly suitable for coffee cultivation. Ethiopia's nine major coffee-producing regions are centered around the capital Addis Ababa: Harar in the east, Sidamo in the south (Yirgacheffe is the most renowned coffee town in Sidamo), Kaffa Forest in the southwest (famous coffee cities from north to south in this region include Teppi, Gimbi, and Limu), and Illubabor in the west, with Lekempti in the north and south.

Ethiopian coffee is classified into two types based on processing methods: washed coffee and sun-dried coffee.

Washed coffee beans are processed from freshly harvested, fully ripe fruits. The carefully selected, clean coffee beans must be pulped on the same day of harvest, then undergo fermentation, washing, drying, and hulling.

Sun-dried coffee beans are mainly harvested by families. Red coffee cherries are dried on cement floors or raised beds, then hulled and sorted.

The natural characteristics of coffee beans include size, shape, acidity, texture, flavor, and aroma. Ethiopian coffee beans are small and aromatic. Their flavor profiles are incredibly diverse, ranging from citrus (such as bergamot) and floral notes to candied fruits and even tropical fruit aromas. The best washed coffees may exhibit elegant, complex, and delightful flavors, while the finest sun-dried processed coffees present exuberant fruit aromas with unusually captivating characteristics.

Coffee from this region is truly exceptional. Many washed coffee beans from Yirgacheffe carry explosive aromas with rich citrus and floral notes, offering a light and elegant mouthfeel. Undoubtedly, this is one of the best and most interesting coffee-producing regions: the finest coffees from this area command premium prices. For many, these coffees taste more like Earl Grey tea and are absolutely worth trying. This region also produces sun-dried processed coffees with unique and delicious flavors.

Knowledge Point: Arabica is one of the two most important varieties in the commercial coffee industry, with the other important variety being Robusta.
