Introduction:Delve into how the Idido Cooperative in Ethiopia's Yirgacheffe region cultivates uniquely flavored specialty coffee beans through high-altitude environments and red honey processing. This article takes you from the origin background, processing techniques, to actual roasting and pour over parameters, helping you understand the aroma layers, sweetness profile, and brewing tips of this G1 grade heirloom coffee, offering a practical guide for coffee enthusiasts seeking depth of flavor.
As a representative specialty coffee-growing region in Ethiopia, Yirgacheffe’s Idido Cooperative stands out with its high-altitude valleys, advantage of heirloom varieties, and refined processing craftsmanship, consistently producing coffee beans with distinct flavors. Located around the town of Yirgacheffe, this cooperative benefits from an altitude of approximately 2000 to 2200 meters, abundant annual rainfall between 1400 to 1800 millimeters, along with cool mountain breezes and fertile soil. These ideal conditions allow coffee cherries to ripen slowly, developing unique aromas and taste profiles.
The Idido Cooperative is part of the Yirgacheffe Coffee Farmers Cooperative Union (YCFCU), established in 2002 and comprising 24 primary cooperatives serving around 50,000 farmers. Not bound by the regulations of the Ethiopian Commodity Exchange (EXC), the cooperative can directly communicate with international buyers, providing detailed coffee profiles including information on the growing region and producers to ensure traceability. This direct trade model not only ensures fair compensation for farmers but also enables them to access processing equipment or financial support, further enhancing coffee quality.
The standout qualities of Idido Cooperative’s coffee lie in four main advantages: the high-altitude environment slows fruit ripening, allowing richer flavors to develop; refined processing techniques preserve the delicate nuances of the coffee; nutrient-rich soil provides an excellent foundation for growth; and the use of Ethiopia’s native heirloom varieties delivers distinctive regional character. One coffee tasting team noted that this coffee exhibits an impressive floral aroma reminiscent of Geisha.
The so-called "Red Cherry Project" (ORC) originated in 2007 when Dutch green coffee trader Trabocca launched it in search of high-quality Ethiopian beans. The project requires farmers to harvest only 100% fully red-ripe coffee cherries, all handpicked. These bright red fruits, akin to cherries, have high sugar content, which contributes to more pronounced sweetness and complex flavors in the coffee. The project places special emphasis on meticulous bean selection, usually carried out by experienced Ethiopian women whose careful sorting significantly improves overall coffee quality, and also makes these beans relatively more expensive.
Red honey processing is the core technique behind this coffee. The hallmark of honey processing is retaining the mucilage layer—that which remains after removing the outer fruit skin—followed by sun drying and fermentation. Compared to washed processing, which removes all pulp, honey processing retains some mucilage to enhance sweetness and body. Among these, red honey processing retains about 75% of the mucilage, sitting between yellow honey (60%) and black honey (nearly 100%), resulting in a balanced flavor profile. One coffee tasting team found that red honey processed beans offer a smooth mouthfeel with sweet, berry juice-like notes, and a noticeably elevated sweetness.
A certain coffee brand roasted this Yirgacheffe red honey processed Red Cherry using a Yangjia 800N semi-direct-fire roaster, with a batch size of 550 grams. The charge temperature was set at 180°C, initial flame power at 130, and the air vent opened to 3. The turning point occurred at approximately 1 minute and 32 seconds. When the drum temperature dropped to 146°C, the air vent was adjusted to 4, with flame power remaining unchanged; at 149°C, the bean surface turned yellow and grassy notes faded, entering the drying phase. When the drum temperature reached 166°C, the flame power was reduced to 110, with no change to the air vent. At around 7 minutes and 43 seconds, the bean surface showed wrinkles and dark speckles, the toast bread aroma transitioned to coffee fragrance, and close attention was needed to monitor the first crack. By 8 minutes and 29 seconds, the first crack began, the air vent was adjusted to 5, and the development phase after first crack lasted 1 minute and 28 seconds, with the roast completed at 190°C.
During cupping of this coffee, a team conducted the session within 8 to 24 hours post-roast, using 200ml ceramic cupping bowls, water at 94°C, grind size passing 70%-75% through a standard 20-number sieve (0.85mm), with a brew ratio of 1:18.18 (11 grams of coffee to 200ml of hot water). The immersion time was 4 minutes, ensuring extraction concentration fell within the Golden Cup range of 1.15%-1.35%. The freshly ground coffee emitted a fresh floral aroma, such as jasmine and ginger lily. After pouring hot water, the sweet aroma of berry juice intermingled with jasmine. On tasting, a bright citrus-like acidity was first perceived, followed by a berry juice character, with lingering honey sweetness and almond aroma in the aftertaste.
Suggested parameters for pour over brewing this coffee are: using a V60 #01 filter cone, water temperature at 90–91°C, coffee dose of 15 grams, brew ratio of 1:15, and medium-fine grind (sifted through a 20-number sieve to 80% retention). Brewing steps: Wet the filter paper and preheat the equipment, then pour 30 grams of water for a 30-second bloom. Follow with a slow, circular pour to reach 125 grams, then pause until the water level drops nearly to exposing the coffee bed, then continue pouring to 225 grams and stop. Wait again until the water level nears exposing the coffee bed before removing the filter. Total brew time is approximately 2 minutes and 7 seconds. This method yields a coffee with aromas of ginger lily, flavors of citrus, lemon, and fruit candy upfront, mid-palate notes of cedar and honey sweetness, and a finish with oolong tea aftertaste, all wrapped in a creamy smoothness.
