01 | Region Introduction

Yirgacheffe is a small town in Ethiopia sitting at an altitude of 1,700-2,100 meters. It has become synonymous with specialty Ethiopian coffee. Historically this area was wetland — the ancient word "yirga" means "settle down," while "cheffe" means "wetland." Yirgacheffe therefore translates to "let us settle and thrive in this wetland."

Yirgacheffe (Specialty Region): Altitude 1,800-2,000 meters | Garden Coffee System

Yirgacheffe is administratively part of the Sidamo region, but it was separated out because of its distinctive flavor profile.

Beyond the town of Yirgacheffe itself, the region includes three surrounding sub-regions: Wenago, Kochere, and Gelena Abaya.

Within Yirgacheffe there are numerous villages, micro-regions, cooperatives, and processing stations. Across most of Ethiopia, coffee farmers still face significant challenges and lack the resources to build their own family processing facilities. As a result, many processing stations have emerged to buy coffee cherries collectively from surrounding smallholders, process them, and then sell to green bean buyers.

Coffee trees are mostly planted in farmers' backyards or intercropped with other crops. Each household's production is relatively small, making this a typical garden coffee system. Nearly all award-winning Yirgacheffe beans come from those coffee villages and communities.

The so-called "Yirgacheffe flavor" means intense jasmine florals, lemon or lime citrus acidity, and peach or almond sweetness with tea-like notes. The phrase "flowers bloom as the coffee enters your mouth" captures the experience perfectly, evoking the pleasant sensation of blossoms stimulating the taste buds and olfactory receptors. Beyond the floral aromas, the delicate body feels like silk massaging the palate — a truly remarkable tactile experience. Many coffee scientists are now studying the microclimate and soil conditions of Yirgacheffe to develop a cultivation formula for specialty coffee.

Strictly speaking, Yirgacheffe is a sub-region within Ethiopia's Sidamo province, located in the northwestern part of Sidamo and surrounded by mountains and lakes. It is one of Ethiopia's highest-altitude coffee-growing regions. Yirgacheffe itself is a small town of approximately 20,000 people. The three neighboring small regions — Wenago, Kochere, and Gelena Abaya — produce coffee with flavors nearly identical to Yirgacheffe, so they too are classified within the Yirgacheffe region. The production methods and flavors here are so distinctive that Ethiopian farmers compete proudly to have their coffee associated with Yirgacheffe characteristics. That is what led to its separation from the Sidamo region, making it a distinguished appellation in its own right and Africa's most renowned coffee region.

02 | Worka Cooperative

Washed Ethiopian coffee can reach the highest G1 grade, which is quite rare to find.

This bean comes from a single farm in Ethiopia, processed by the Worka Cooperative. The Alemayehu Alako farm is a member of the Worka Cooperative.

The Worka Cooperative was established in 2005 and joined the famous Yirgacheffe Coffee Farmers Cooperative Union (YCFCU) the same year, known for producing high-quality natural-processed Yirgacheffe coffee. The Worka Cooperative has approximately 300 coffee farmers. YCFCU was founded in 2002 and includes 26 other cooperatives, serving over 45,000 coffee farmers.

Worka lies in the southeasternmost part of Yirgacheffe, in the Gedeb region. In earlier years, coffee from this area was exported under the Worka name or processed by the Worka Cooperative. Over the past two to three years, however, independent single-origin lots have been discovered one by one by coffee hunters worldwide, such as Banko Gotiti, Banko Dadhato, and Halo Bariti. Gotiti village was one of the first village areas to be separated several years ago, and many individual smallholders there were originally members of the Worka Cooperative, so their coffee production skills are naturally excellent.

The Worka Cooperative is located in the southern part of the Gedeb region and was established in 2005, joining the renowned Yirgacheffe Coffee Farmers Cooperative Union (YCFCU) the same year. It is known for producing high-quality natural-processed Yirgacheffe coffee. The Worka Cooperative has approximately 300 coffee farmers. YCFCU was founded in 2002 and includes 26 other cooperatives, serving over 45,000 coffee farmers.

03 | Processing Method

The refined processing method in the Yirgacheffe region is predominantly washed. The beans are placed in washing tanks for approximately 72 hours to ferment and remove the pulp. Some of the acids produced during mucilage fermentation enter the beans. And because the fruit pulp and mucilage are no longer attached to the parchment during drying, the characteristic fruity notes of natural-processed coffee are absent. The flavor profile tends toward clean and bright, with more pronounced acidity. Drying happens right outside the processing facility. After the green beans are hand-selected, they undergo quality inspection by the Ethiopian Coffee and Tea Authority and are exported through competitive bidding.

Annual production is approximately 225,000 bags (60kg each), with traditional markets mainly in Northern Europe (primarily Germany) and Japan, though North American attention has been growing recently.

Washed coffee is less likely to carry wild flavors, offering pure, refreshing qualities suited to light roast levels. This washed Ethiopian coffee reaches the highest G1 grade, indicating very few defects.

04 | Green Bean Analysis

Heirloom varieties are unique to Ethiopia, encompassing a wide array of types including Typica, Mocha, Bourbon, and others. The Kaffa Forest is the cradle of Arabica coffee. While only hundreds of varieties exist worldwide (including both original and derived types), this treasure trove holds tens of thousands, most of which remain unclassified. "Heirloom" is Ethiopia's own designation, as if telling the world that its varieties encompass everything, captured in a single word. The green beans are blue-green in color and relatively uniform in size.

African coffee beans use a grading system based on the percentage of defective beans. The highest grades for washed coffee are G1 and G2; for natural-processed coffee, the highest grades are G1 and G3.

What does that mean? As follows:

Washed: Grade-1; Grade-2 (G1>G2)

Natural: Grade-1 and Grade-3~Grade-5 (G1>G3>G4>G5)

Several points to note:

a) Both washed and natural coffees can achieve Grade 1, with the criteria being "zero defects" and Premium Cup. Whether washed or natural, Grade 1 is the rating for the best of the best in specialty coffee or Cup of Excellence coffee.

b) The lowest grade for natural-processed Yirgacheffe and Sidamo is Grade 4.

c) Beans of the same grade, such as Grade 2 Limu, can vary in quality depending on the exporter's sorting level and investment.

d) Given the current "zero defect" requirement, Grade 1 beans (whether washed or natural) are extremely rare, because of high processing costs and the fact that very few suppliers undertake this level of quality control.

05 | Roasting Analysis

The beans have quite high density. For roasting, use higher heat to climb, with the yellowing point around 5 minutes and 30 seconds. Then reduce heat and open the air damper to enter the Maillard reaction. At 160°C, reduce heat again to prolong the Maillard reaction. First crack occurs around 186.3°C. This washed coffee requires a heat reduction before first crack to prevent an excessive rise and bitterness. Drop at 194.2°C after 1 minute and 40 seconds of development.

Roasting machine: Yangjia 600g semi-direct flame

Preheat the roaster to 200°C before loading, with the air damper set to 3. After 30 seconds, ignite the burner and adjust heat to 160. Temperature recovery point at 1:32. Yellowing at 5:30, the grassy aroma disappears, entering the dehydration stage. Reduce heat to 120, air damper to 4. At 170°C, reduce heat again to 50.

After eight minutes, dehydration is complete. The bean surface shows wrinkles and black spots, and the toast aroma turns to coffee aroma — the prelude to first crack. Reduce heat to 40 and listen carefully for first crack. First crack begins at 9:00; adjust heat to 40 and open the air damper fully to 5. Development time after first crack is 1 minute and 40 seconds, dropping at 194.2°C.

Flavor: this meticulously washed coffee brings out more delicate and distinct acidity, presenting yellow lemon notes, caramel sweetness, and cream and lemon tea flavors, with a floral aftertaste.

06 | Brewing Analysis

Three-stage water pouring, or segmented extraction.

This method creates richer layers, clearly distinguishing the front, middle, and back-end flavors of the coffee. After blooming, increase the water amount each time, typically pouring when the coffee level is about to drop to the surface of the coffee bed. Use small, medium, and large water flows for the three-stage extraction:

Recommended brewing methods: Siphon, Pour-over

Grind size: 3.5 (Japan Fuji R440)

V60 filter cup, 15g coffee, water temperature 90°C, grind 3.5, water-to-coffee ratio close to 1:15

30g water for blooming, bloom time 30s

Segments: pour water to 120g, stop, then slowly pour to 225g

That is 30-120-225

Other drip extraction recommendations:

French Press: recommended grind 3.5-4, water temperature 86-88°C

AeroPress: recommended grind 2.5, water temperature 86-88°C
