How do Yirgacheffe coffee grades shape Adola beans?
Ethiopia does not grade coffee by screen size but by the proportion of defective beans in the green coffee. Under the ECX system introduced in October 2009, Q-Graders sort washed Yirgacheffe into Grade 1 and Grade 2, while natural Yirgacheffe has Grade 1, 3, 4, and 5, with Grade 1 meaning the lowest defect rate.
Adola natural beans reach that top tier through strict sorting. Underripe and defective cherries are removed by hand before drying, moldy ones again during it, and over two weeks the pulp sugars permeate the bean as moisture falls to 12 percent. Density and color tests follow, then a final visual check.
Yirgacheffe is Ethiopia's most representative specialty coffee region, and its grading system is based not on screen size but on the proportion of defective beans. This article focuses on the cultivation of Adola specialty coffee beans, outlining Yirgacheffe's geographical location, altitude and climate, planting systems, the flavor differences between washed and natural processing methods, and the grade classifications under the ECX grading system. The article also records how Front Street Natural Yirgacheffe G1 surpasses same-grade washed beans in quality, making it suitable reading for coffee enthusiasts who want to gain a deeper understanding of the Yirgacheffe region.
Ethiopia's grading of coffee beans is not based on screen mesh size, but rather depends on the proportion of defective beans in the green coffee. In October 2009, the country introduced the ECX specialty coffee trading and grading system, under which Q-Graders evaluate green beans and make the following classifications:
Washed Yirgacheffe is divided into two grades: Grade 1 and Grade 2;
Natural Yirgacheffe has four tiers: Grade 1, Grade 3, Grade 4, and Grade 5,
with Grade 1 representing the highest level—that is, Yirgacheffe with the lowest defect rate and the best quality.
Natural Yirgacheffe has strict standards at the red cherry picking stage: before the fruit is spread out to dry, underripe green cherries and defective cherries are removed by hand, and during drying, damaged or moldy cherries are removed again. Over two weeks, the sugars and essence of the fruit pulp fully permeate the bean, and the moisture content drops to 12%. The hardened pulp, mucilage layer, and pod are then sent together into a depulper to be scraped clean. After the coffee beans are extracted, they must also undergo density and bean color testing. After defective beans are eliminated, workers finally pick out by eye any defective beans that slipped through. This layer-by-layer screening and quality control creates the clean, refined character and rich, alluring fruit aroma of Yirgacheffe natural beans. By 2015, Front Street Natural Yirgacheffe had already appeared at the G1 grade, surpassing G1 washed beans in both quality and appearance.
These beans are roasted until the first crack is密集, then brewed by pour-over or siphon. When grinding, the striking natural fruit aroma is already noticeable, with prominent sweetness, while also carrying the signature citrus and jasmine floral notes of Front Street washed Yirgacheffe. On the palate, it is like a combined flavor of Harar, Yemen Mocha, and Front Street washed Yirgacheffe. Yirgacheffe uses the oldest natural processing method, but in 1972 Ethiopia introduced Central and South American washing techniques to improve quality, making the jasmine and citrus aromas of Front Street Yirgacheffe appear clearer and more refined,
catapulting it into the ranks of the world's finest specialty beans—a feat to which superb washing techniques contributed immensely. After the 1970s, this region was dominated by washed processing and became Ethiopia's hottest washed-bean producing region.
However, in the past two years, Yirgacheffe has broken with convention and frequently released stunning natural beans, becoming a rising star in the specialty market.
Front Street Natural Yirgacheffe beans are small, neat, short, and round. Ethiopian natural beans are usually G3 to G5, but these beans reach G2, equivalent to the grade of washed beans. Although there are still a few defective beans, compared with the natural beans of Harar and Sidamo, this is already quite remarkable.
Yirgacheffe is a small town in Ethiopia at an altitude of 1,700 to 2,100 meters, and it is also synonymous with Ethiopian specialty coffee. Since ancient times, this place has been a wetland. In the ancient language, "yirga" means "to settle down," and "cheffe" means "wetland." Therefore, Yirgacheffe means "let us settle down in this wetland."
Strictly speaking, Yirgacheffe is a sub-region of Ethiopia's Sidamo Province, located on the northwestern edge of Sidamo, beside mountains and lakes, and is one of Ethiopia's highest-altitude coffee-producing regions. However, its production methods and flavors are so outstanding that Ethiopian coffee farmers compete to take pride in their coffee having Yirgacheffe flavor. As a result, it became independent from the Sidamo region and established its own identity, also becoming Africa's most famous coffee-producing region.
Although Ethiopia's Yirgacheffe coffee beans are small in size, they are gentle, elegant, sweet, and lovely. As the birthplace of coffee, Ethiopia's thousand-year planting history and processing traditions have produced high-quality washed Arabica beans. Light roasting brings unique lemon, floral, and honey-like sweet aromas, soft fruit acidity, and citrus notes, with a fresh and bright mouthfeel. With no milk and no sugar, its rich body and unique soft floral aroma brush across the palate, leaving an endless aftertaste...
The highest grades of Sidamo (Yirgacheffe, Sidamo) are Grade 2 and Grade 3 (G2, G3),
while natural-processed coffee from eastern Ethiopia is mostly Grade 4 or Grade 5 (G4, G5).
In many cases, Grade 4 coffee is labeled as Grade 5 in order to reduce taxation. Today's grading is not very uniform and is somewhat chaotic, because there are also Grade 1 and Grade 2 (Grand G2) Yirgacheffe coffees processed by the natural method, while the highest grade for Harar is Grade 4. Ethiopia is the birthplace of Arabica coffee. It is in the forests of Ethiopia's Kaffa region that you can see wild Arabica coffee. In Ethiopian language, coffee is called "Bun" or "Buna," and coffee bean may have been translated from "Kaffa Bun." Arabica coffee was discovered in the Harar region very early on, and it most likely came from the Kaffa forests.
Ethiopian coffee is processed by two methods, natural and washed, and the flavors of coffee processed by different methods vary greatly. Overall, washed Sidamo, Yirgacheffe, and Limmu coffees have slightly lower body and earthy notes, while natural-processed coffees taste wilder. However, the taste of each batch of Ethiopian coffee may differ, which requires more cupping in order to find truly good coffee.
Yirgacheffe is a small town at an altitude of 1,700 to 2,100 meters, and it is synonymous with Ethiopian specialty coffee. Since ancient times, this place has been a wetland. In the ancient language, "Yirga" means "to settle down," and "Cheffe" means "wetland." The production methods and flavors of coffee here are so outstanding that Ethiopian coffee farmers compete to take pride in their coffee having Yirgacheffe flavor, which in turn made it Africa's most famous coffee-producing region.
Initially, the coffee trees of Yirgacheffe were planted by European monastery monks, and later this was taken over by farmers or cooperatives. Yirgacheffe is actually built up from the surrounding coffee communities or cooperatives, generally including Harfusa, Hama, and Biloya.
These small mountain villages are shrouded in mist, spring-like throughout the year, with gentle summer breezes—cool but not hot, rainy but not damp—and no cold damage in winter either, nurturing a unique regional flavor of citrus and florals. Coffee trees are mostly planted in farmers' own backyards or intercropped with other crops on farmland. Yirgacheffe is a region under Ethiopia's Sidamo Province. Because its coffee has a unique flavor, it became famous, and the name Yirgacheffe even overshadowed the name of its province, Sidamo. Recently, Yirgacheffe in China can be said to be everywhere, and more and more coffee enthusiasts are familiar with all kinds of Yirgacheffe.
In the Yirgacheffe region there are many high-quality coffee processing plants, and many coffees have soared in value because they come from these processing plants. The natural beans produced by the Kebel Aricha Mill are one of them. This coffee is also what we often call ARICHA beans. After being processed by the Kebel Aricha processing plant using a refined natural method, it was classified by ECX as Gr.1 or G1 (Ethiopia's highest coffee grade), and is known as the "king of fruits." Its mouthfeel is also relatively thick, with a bit of chocolate and caramel flavor. The acidity is not very obvious, and it is even thicker and lower-toned than pour-over, with a slight jasmine tea flavor, obvious sweet aftertaste, and a relatively lasting finish in the mouth. The fermented flavor is not as strong as in the previous pour-over. As the temperature drops, the acidity increases somewhat, making it appear brighter, and the mouthfeel also seems a bit cleaner. In short, when brewed with a French press, the coffee feels heavier and lower-toned, with a stronger flavor. Overall, the citrus aroma is still not obvious and is even hard to find, but it has the characteristics of natural beans: rich and mellow, with a fermented flavor. Using a French press best interprets the coffee's original flavor, but some people may not get used to the mouthfeel of the coffee grounds left by the French press. I am using here a Bodum French press made for Starbucks; the filter mesh is very strong, but there are still some coffee grounds.
Ethiopia's coffee-producing regions are Sidamo, Harrar, and Yirgacheffe. Sidamo and Harrar are provinces and administrative divisions. Sidamo is located in southern Ethiopia bordering Kenya, and Harrar is in eastern Ethiopia bordering Somalia. Although Yirgacheffe is a small area within the greater Sidamo region, due to factors such as soil composition and moisture content, the coffee it produces is considered Ethiopia's best.
In the West, Ethiopian coffee is generally labeled as<耶加雪菲><西达莫>and<哈拉尔>(Yirgacheffee, Sidamo and Harrar) for sale on the market.
In the specialty coffee field, there are also coffees from five other small places, namely Limmu, Djimmah, Lekempti, Bebeka, and Wolega. What is seen most often is still either Sidamo or Harrar coffee. Ethiopian coffee grades:

Initially, the coffee trees of Yirgacheffe were planted by European monastery monks (a bit like Belgian monks growing wheat to brew beer), and later this was taken over by farmers or cooperatives. Yirgacheffe is actually built up from the surrounding coffee communities or cooperatives, including Idido, Harfusa, Hama, and Biloya near Misty Valley. They all use washed processing, but a small amount of exceptional beans is deliberately processed as natural to enhance the alluring fruit aroma and body. These small mountain villages are shrouded in mist, spring-like throughout the year, with gentle summer breezes—cool but not hot, rainy but not damp—and no cold damage in winter either, nurturing a unique regional flavor of citrus and florals.
Coffee trees are mostly planted in farmers' own backyards or intercropped with other crops on farmland. Each household's output is not large, making it a typical garden coffee. Yirgacheffe award-winning beans almost all come from the above coffee villages and communities. The so-called "Yirgacheffe flavor" refers to rich jasmine floral aroma, lemon or lime acidity, and sweet peach and almond notes or tea aroma. The phrase "coffee enters the mouth, a hundred flowers bloom" is the most appropriate way to describe it, just like flowers stimulating the taste buds and nasal olfactory cells with a sense of comfort. In addition to the floral aroma, the delicate body is like silk massaging the mouth, with a wonderful tactile sensation. At present, many coffee chemists have begun to study the microclimates and terroir around Yirgacheffe in order to summarize a cultivation formula for specialty coffee.
Yirgacheffe is divided into two major categories according to the processing method of green coffee beans: Category A is the washed processing method, with grade standards established by the Specialty Coffee Association of America (SCAA), divided into Gr-1 and Gr-2. The smaller the Arabic numeral, the higher the grade. Front Street G1 Yirgacheffe has a distinctive style, and the flavor of citrus and floral notes fused into the coffee liquid is a deliciousness no one can resist. Category B is green coffee beans processed by the natural method, with grades divided into Gr-1, Gr-3, Gr-4, and Gr-5. Likewise, the highest grade, Front Street G1 Natural Yirgacheffe, is rich in fruit aroma. Opening a bag of freshly roasted Front Street G1 Natural Yirgacheffe coffee can overturn everyone's original understanding of coffee. Only those who have tasted the highest-grade Front Street Natural Yirgacheffe will believe that coffee is a fruit—
Yirgacheffe is a small town in Ethiopia at an altitude of 1,700 to 2,100 meters, located on the northwestern side of Sidamo Province, beside mountains and lakes. It is one of Ethiopia's highest-altitude coffee-producing regions and also synonymous with Ethiopian specialty coffee.
Strictly speaking, Yirgacheffe is a sub-region of Ethiopia's Sidamo producing region, and it was made independent because of its special flavor. In addition to the small town of Yirgacheffe, it also includes three surrounding sub-regions: Wenago, Kochere, and Gelena/Abaya.
1. Planting system and environment
The small mountain villages of the Yirgacheffe producing region are cool and foggy, spring-like throughout the year, with gentle summer breezes—cool but not hot, rainy but not damp—and no cold damage in winter either, making it the best environment for planting Arabica. There are no large coffee plantations here. Coffee farmers interplant coffee with other crops, generally under banana trees, forming a unique landscape.
2. Processing methods
Ethiopia's traditional natural processing method is relatively rough, with heavy off-flavors, and has been criticized for this. In 1959, the Yirgacheffe producing region introduced the South American washed processing method. Most producing regions generally use washed processing, that is, after the coffee cherries are depulped, the mucilage layer is removed through fermentation and washing, and then the beans are dried.
Since 2006, some coffee processing plants in certain producing regions have adopted a refined raised-bed natural drying method. This raised-bed drying method, which requires intensive manual labor, isolates the coffee cherries from contact with the ground and prevents the earthy off-flavors produced during natural drying, creating an exceptionally clean fruit flavor. After more than two weeks of drying, the dark brown coffee cherries are professionally stored, waiting for the full flavor to mature. Before sale, the dried cherry pulp and parchment are removed, and then underripe beans and over-fermented beans are removed. Strict control has greatly improved the quality of natural beans.
