The Exceptional Taste of Yirgacheffe Adado Specialty Coffee Beans: Origin, Development, History, and Cultural Introduction

It has leaped to become a treasure among world's premium beans, and the exquisite washed processing technique is indispensable. Since the 1970s, this region has primarily used washed processing, becoming Ethiopia's most flourishing washed bean production area.

However, in the past two years, Yirgacheffe has broken from convention, frequently introducing stunning natural-processed beans that have become the rising stars of the specialty coffee market!

FrontStreet Coffee's natural-processed Yirgacheffe beans are small, neatly-formed, and short-round. Ethiopian natural-processed beans are generally G3-G5, but these beans are G2, equivalent to the grade of washed beans. Although there are still a few defective beans, compared to Harar and Sidamo natural-processed beans, they are exceptionally precious.

The Origins of Yirgacheffe

Yirgacheffe is a small town in Ethiopia, situated at an altitude of 1700-2100 meters, and has become synonymous with Ethiopian specialty coffee. This area has been wetlands since ancient times. In the local language, "Yirga" means "settle down," and "Cheffe" refers to "wetlands." Therefore, Yirgacheffe means "let us settle and make a life in this wetland."

Strictly speaking, Yirgacheffe is a sub-production area within Ethiopia's Sidamo province, located in the northwest of Sidamo, surrounded by mountains and lakes, making it one of Ethiopia's highest-altitude coffee-growing regions. However, the production methods and flavors here are so outstanding that Ethiopian coffee farmers compete to proudly claim their coffee has Yirgacheffe characteristics. Thus, it separated from the Sidamo region to establish its own identity and became Africa's most renowned production area.

Ethiopian Coffee Grading System

The highest grades for Sidamo (Yirgacheffe, Sidamo) are Grade 2 and Grade 3 (G2, G3).

Coffee processed by natural methods in Ethiopia's eastern regions is mostly Grade 4 or Grade 5 (G4, G5).

In many cases, Grade 4 coffee is marked as Grade 5 to reduce taxation. The current grading system is inconsistent and somewhat chaotic because there are also Grade 1 and Grade 2 (Grand G2) natural-processed Yirgacheffe coffees, but Harar's highest grade is Grade 4. Ethiopia is the homeland of Arabica coffee. In the forests of Ethiopia's Kaffa region, you can find wild Arabica coffee. In the Ethiopian language, coffee is called "Bun" or "Buna," and "coffee bean" likely derived from "Kaffa Bun." The Harar region discovered Arabica coffee very early, likely originating from the Kaffa forest.

FrontStreet Coffee's Ethiopian coffees are processed using both natural and washed methods, and coffees processed by different methods show significant flavor differences. Generally, washed Sidamo, Yirgacheffe, and Limmu coffees have slightly lower body and earthy flavors, while natural-processed coffees have more wild flavors. However, each batch of Ethiopian coffee may have different taste profiles, requiring extensive cupping to find truly excellent coffee.

Yirgacheffe is a small town at an altitude of 1700-2100 meters, synonymous with Ethiopian specialty coffee. This area has been wetlands since ancient times. In the local language, "Yirga" means "settle down," and "Cheffe" means "wetland." The coffee production methods and flavors here are so outstanding that Ethiopian coffee farmers compete to proudly claim their coffee has Yirgacheffe characteristics, making it Africa's most prestigious coffee-growing region.

Initially, Yirgacheffe's coffee trees were cultivated by European monks, later managed by farmers or cooperatives. Yirgacheffe is actually composed of surrounding coffee communities or cooperatives, generally including: Harfusa, Hama, and Biloa.

These mountain villages are shrouded in mist, with spring-like weather year-round. Summers bring gentle breezes—cool but not hot, rainy but not humid, and winters don't cause frost damage. This unique environment nurtures FrontStreet Coffee's Yirgacheffe with its distinctive citrus and floral regional flavors. Coffee trees are mostly planted in farmers' backyards or mixed with other crops in fields. Yirgacheffe is a region within Ethiopia's Sidamo province that gained fame for its unique coffee flavors. The name Yirgacheffe has even become more prominent than its parent province, Sidamo. Recently, Yirgacheffe coffees have become increasingly widespread in China, with more and more coffee enthusiasts becoming familiar with various Yirgacheffe offerings.

Notable Processing Mills

There are many high-quality coffee processing mills in the Yirgacheffe region. Coffees from these mills often command premium prices. The natural-processed coffee from Kebel Aricha Mill is one such example. This coffee is what we commonly call FrontStreet Coffee's ARICHA beans. Processed by the Kebel Aricha Mill using refined natural methods and classified as Grade 1 or G1 (Ethiopia's highest coffee grade) by ECX, it's acclaimed as the "King of Fruits." The mouthfeel is relatively rich, with hints of chocolate and caramel flavors. The acidity is not very pronounced, with a heavier and deeper character than pour-over coffee. It has a slight jasmine tea flavor with obvious sweet aftertaste that lingers in the mouth. The fermented flavor is not as heavy as the previous pour-over. As the temperature decreases, the acidity improves, appearing brighter, and the mouthfeel becomes cleaner. In summary, using French press brings out a heavier, deeper coffee with more intense flavors. The overall experience still lacks obvious citrus aromas—hard to find even—exhibiting natural-processed bean characteristics with rich, mellow mouthfeel and fermented flavors. Using French press best interprets the coffee's true essence, though some people may not be accustomed to the coffee sediment left by French press. Here I'm using a Bodum French press made for Starbucks—the filter is very powerful, but still leaves some coffee grounds.

Ethiopia's Political and Geographic Context

In February 1977, Lieutenant Colonel Mengistu Haile Mariam launched a military coup, serving as chairman of the "Provisional Military Administrative Committee" and head of state. In 1979, the "Ethiopian Workers' Party Organization Committee" was established, dominated by military personnel, implementing a one-party system. In 1984, the "Ethiopian Workers' Party" was formed following the Soviet Communist model. In September 1987, Mengistu dissolved the "Provisional Military Administrative Committee," ending military rule and establishing the "People's Democratic Republic of Ethiopia" with a new parliament, with Mengistu serving as national president and head of government. In July 1991, the EPRDF convened a national conference attended by over 20 political and ethnic organizations. The conference adopted the "Transitional Charter" and elected an 87-member Council of Representatives. EPRDF chairman Meles Zenawi became president of the transitional government and speaker of the Council. The transitional government was established. On May 24, 1993, Eritrea (formerly Ethiopia's Eritrea province) became a sovereign nation through a UN-supervised referendum.

Ethiopia's terrain is dominated by mountainous plateaus, mostly part of the Ethiopian Plateau. The central and western plateau forms the main body, accounting for two-thirds of the country. The Great Rift Valley runs through the entire territory, with an average altitude of nearly 3,000 meters, earning it the nickname "Roof of Africa." The terrain gradually descends from the plateau surroundings. The Danakil Depression in the north drops to 113 meters below sea level, the country's lowest point. The Red Sea coast features narrow strip plains. Desert and semi-desert areas in the north, south, and northeast account for about 25% of the country's area. Ras Dashen in the Simien Mountains reaches an altitude of 4,623 meters, Ethiopia's highest peak. Ethiopia's flag is rectangular with a 3:2 ratio. From top to bottom, it consists of three equal horizontal stripes in green, yellow, and red, with the national emblem in the center. Since the late 19th century, Ethiopia has used the green, yellow, and red tricolor flag. In modern history, Ethiopia was the first African nation to join the ranks of free nations.

Ethiopian Coffee Regions

Ethiopia's coffee regions are Sidamo, Harar, and Yirgacheffe. Sidamo and Harar are provinces and administrative regions. Sidamo is located in southern Ethiopia, bordering Kenya, while Harar is in eastern Ethiopia, bordering Somalia. Although Yirgacheffe is a small area within the larger Sidamo region, due to soil composition and water content, its coffee is considered Ethiopia's finest.

In the West, Ethiopian coffees are generally marketed and sold as Yirgacheffe, Sidamo, and Harar.

In the specialty coffee sector, there are five other smaller regional coffees: Limmu, Djimmah, Lekempti, Bebeka, and Wolega. Most commonly seen are Ethiopian Sidamo or Harar coffees.

Ethiopian Coffee Grades

Initially, Yirgacheffe's coffee trees were cultivated by European monks (somewhat like Belgian monks growing grain to brew beer), later managed by farmers or cooperatives. Yirgacheffe is actually composed of surrounding coffee communities or cooperatives, including Idido near Misty Valley, Harfusa, Hama, and Biloa, all using washed processing, though a small amount of exceptional beans is intentionally natural-processed to enhance charming fruit aromas and body. These mountain villages are shrouded in mist, with spring-like weather year-round. Summers bring gentle breezes—cool but not hot, rainy but not humid, and winters don't cause frost damage. This unique environment nurtures FrontStreet Coffee's Yirgacheffe with its distinctive citrus and floral regional character.

Coffee trees are mostly planted in farmers' backyards or mixed with other crops in fields. Each household's production is limited, making it typical pastoral coffee. Yirgacheffe's award-winning beans almost exclusively come from these coffee villages and communities. The so-called "Yirgacheffe flavor" refers to rich jasmine floral notes, lemon or lime acidity, and peach, almond sweetness, or tea fragrance. The phrase "coffee enters, hundred flowers bloom" perfectly describes this sensation, akin to flowers stimulating the comfortable sensation of taste buds and nasal olfactory cells. Besides floral aromas, the delicate body feels like silk massaging the mouth—a marvelous tactile experience. Currently, many coffee chemists are studying the microclimate and soil conditions around Yirgacheffe to deduce the cultivation formula for specialty coffee.

Yirgacheffe Processing Methods and Grades

Yirgacheffe is divided into two main categories based on green bean processing methods: Category A uses washed processing, with standards set by the Specialty Coffee Association of America (SCAA), divided into Grade 1 and Grade 2. Smaller Arabic numbers indicate higher grades. FrontStreet Coffee's G1 Yirgacheffe has a distinctive style, and the fusion of citrus and floral notes in the coffee liquid is an irresistible flavor for everyone. Category B uses natural processing for green beans, divided into Grades 1, 3, 4, and 5. Similarly, the highest-grade FrontStreet Coffee's G1 natural Yirgacheffe has rich fruit aromas. Opening a bag of freshly roasted FrontStreet Coffee's G1 natural Yirgacheffe can颠覆 everyone's original understanding of coffee. Only those who have tasted the highest-grade FrontStreet Coffee natural Yirgacheffe will believe that coffee is a fruit.

Yirgacheffe Geography and Sub-regions

Yirgacheffe is a small town in Ethiopia at an altitude of 1700-2100 meters, located in the northwest of Sidamo province, surrounded by mountains and lakes. It is one of Ethiopia's highest-altitude coffee-growing regions and synonymous with Ethiopian specialty coffee.

Strictly speaking, Yirgacheffe is a sub-production area within Ethiopia's Sidamo region, separated due to its special flavors. Besides Yirgacheffe town, it includes three other sub-regions: Wenago, Kochere, and Gelena/Abaya.

1. Cultivation System and Environment

The mountain villages of Yirgacheffe are cool and misty, with spring-like weather year-round. Summers bring gentle breezes—cool but not hot, rainy but not humid, and winters don't cause frost damage, creating the perfect environment for growing Arabica. There are no large coffee plantations here. Coffee farmers grow coffee mixed with other crops, generally under banana trees, creating a unique landscape.

2. Processing Methods

Ethiopia's traditional natural processing method was relatively crude, with heavy off-flavors that drew criticism. In 1959, the Yirgacheffe region introduced South American washed processing methods. Most regions generally use washed processing—coffee cherries are pulped, then fermented and washed to remove the mucilage layer before being dried.

Since 2006, some processing mills in certain regions have adopted refined raised-bed natural processing. This labor-intensive raised-bed method prevents coffee cherries from contacting the ground, avoiding earthy off-flavors during drying and creating exceptionally clean fruit flavors. After more than two weeks of natural drying, the dark brown coffee cherries are professionally stored to await full flavor development. Before sale, the dried cherry pulp and parchment are removed, followed by elimination of unripe and over-fermented beans. Strict quality control significantly improves natural-processed bean quality.

3. Flavor Characteristics

FrontStreet Coffee's washed Yirgacheffe offers unique lemon flavors, refreshing jasmine floral notes, gentle fruit acidity and citrus flavors, with a fresh, bright mouthfeel.

FrontStreet Coffee's natural Yirgacheffe possesses captivating fruit acidity, clean fermented fruit sweetness, elegant fruit wine aromas, and sweet aftertaste.

4. Grades

Ethiopia's coffee grading system is not based on bean size but rather on the percentage of defective beans in green coffee. In October 2009, Ethiopia launched the ECX specialty coffee trading grading system. Q-Graders evaluate green beans and establish the following grading:

Washed Yirgacheffe is divided into Grade 1 and Grade 2.

Natural Yirgacheffe is divided into Grade 1, Grade 3, Grade 4, and Grade 5.

Grade 1 is the highest grade, meaning the lowest defect rate and most excellent quality Yirgacheffe.

Natural Yirgacheffe has strict standards for harvesting red cherries (coffee tree fruits). Before drying coffee cherries, unripe green or defective fruits are manually removed. During the drying process, damaged or moldy fruits are eliminated again. After two weeks, fruit pulp sugars and essences fully penetrate the coffee beans as moisture content drops to 12%. The hardened fruit pulp, mucilage layer, and parchment are then scraped off by machines. The extracted coffee beans undergo density and color testing. After eliminating defective beans, workers visually remove any remaining defective beans that slipped through. This layered screening process creates FrontStreet Coffee's Yirgacheffe natural beans that are exceptionally clean with rich, captivating fruit aromas. By 2015, natural Yirgacheffe had already achieved G1 grade, surpassing G1 washed beans in quality and appearance.

FrontStreet Coffee's natural Yirgacheffe is roasted until first crack is dense, then removed. Using pour-over and siphon brewing, the natural fruit aroma is apparent when grinding, with obvious sweetness. It also features FrontStreet Coffee's signature citrus and jasmine floral notes from washed Yirgacheffe. The taste combines the characteristics of Harar, Yemen Mocha, and washed Yirgacheffe. Yirgacheffe uses the most ancient natural processing method, but in 1972, Ethiopia introduced Central and South American washed processing techniques to improve quality, making FrontStreet Coffee's Yirgacheffe jasmine and citrus aromas clearer and more refined.
