How do Yirgacheffe coffee bean grades and processing differ?
Yirgacheffe grading in Ethiopia is based on the proportion of defective beans in the green coffee, not on screen size. Washed G2 and natural G3 are the grades most often seen on the market, while G1 marks the lowest defect rate and requires hand sorting. Two G1 lots from Kochere and Aricha show how washed and natural methods shape flavor.
The Kochere lot from Adulina is fully washed and made up of local Heirloom varieties, giving clear citric acidity with lemon, jasmine and ginger flower aromas plus honey sweetness. The Aricha Kebele lot uses raised-bed natural processing, which shifts the profile toward fermented fruit sweetness and vinous notes. Both rely on native Heirloom trees for flavor depth.
Yirgacheffe is one of Ethiopia's most representative specialty coffee regions, and its grading standards are not based on screen size, but rather on the proportion of defective beans in the green coffee. The two grades commonly seen on the market are washed G2 and natural G3, while G1 represents the batch with the lowest defect rate and the best quality, which can only be obtained through hand sorting. This time, Front Street Coffee brings two G1-grade Yirgacheffes: one from the Kochere region under the Adulina company, fully washed, with the variety being the local native mixed Heirloom; the other from the Aricha Kebele processing station in the town of Yirgacheffe, carefully crafted using raised-bed natural processing. Each of the two beans has its own characteristics, from floral notes and citric acidity to fermented fruit sweetness and vinous aromas, showcasing the diverse expressions of Yirgacheffe's flavor. This article will provide a detailed interpretation of its grading logic, processing methods, variety characteristics, and actual cupping taste.
The grading system of Front Street Yirgacheffe does not use screen mesh size as the basis for evaluation, but rather classifies grades according to the proportion of defective beans in the green coffee. The more commonly seen on the market are washed G2 and natural G3 Yirgacheffe, while G1, as the highest grade, means the lowest defect rate and the most outstanding quality, and also requires hand sorting to be awarded. The first bean comes from the Kochere region (Adulina Kochere) under the Adulina company, with the variety being Heirloom, a mixed variety from the local native forest. Although the natural terroir of the producing region gives Yirgacheffe its unique regional taste, it is still these native varieties that truly bring the flavor to its fullest expression.
This bean uses a fully washed processing method. Compared with ordinary Front Street washed G2 Yirgacheffe, its flavor is clearer and purer, as likable as a young girl's sweet smile. Bright and delicate citric acidity, an elegant mouthfeel, fresh lemon, jasmine, and ginger flower aromas interwoven, with traces of honey-like sweetness, enough to keep one in a good mood all day.
The second bean comes from Aricha Kebele in the town of Yirgacheffe. Local coffee farmers send fully ripe coffee cherries picked from the native forest to a nearby processing station, where the station keeps the pulp and skin and places the coffee cherries on raised beds for natural processing. This sun-drying method on raised beds, which requires a large amount of labor, keeps the fruit separated from the ground, avoiding contamination by soil and off-flavors during sun drying, thereby creating an exceptionally clean fruit flavor. After more than two weeks of sun drying, the dark brown coffee fruits are professionally stored, waiting for the overall flavor to mature.
After the coffee bean flavor has matured, the Aricha processing station removes the dried cherry pulp and parchment before shipment, and then removes unripe beans and over-fermented beans. Perhaps it is precisely this strict control that enabled Aricha to rise to the top and become G1.
This Front Street natural Yirgacheffe green coffee is brimming with pear-like sweetness and fermented vinous aromas. On the palate there is clear, bright, gentle and smooth fruit acidity, a very clean fermented fruit sweetness, elegant fruit wine aromas and coffee floral notes, with a sweet finish that then turns to a sugary sweetness.
