Introduction:The Gedeb Gedebtindi Cooperative in Yirgacheffe is a small-scale yet highly regarded production unit within Ethiopia’s high-altitude coffee-growing regions. Its washed coffee beans are renowned for their bright acidity and pronounced sweetness. This article delves into the cooperative’s founding background, the characteristics of its native varieties, traditional washed processing methods, and provides professional roasting profiles, cupping records, and V60 pour-over recommendations to help coffee enthusiasts fully grasp the flavor profile and brewing techniques of this classic bean.
In Ethiopia’s Yirgacheffe region, numerous coffee cooperatives play a pivotal role. These non-profit organizations assist members in sourcing production materials and enhancing both the quality and market competitiveness of their coffee beans. Yirgacheffe is celebrated for its high altitude and unique microclimate, which nurture several representative micro-regions and cooperatives, each with its own distinct flavor story. This article will take you deep into the Gedeb Gedebtindi Cooperative located in the southeastern part of Yirgacheffe, exploring everything from its historical development as it separated from the Worka Cooperative to the traits of its native varieties, washed processing techniques, and professional roasting and pour-over suggestions—a comprehensive analysis of this beloved coffee bean.
Yirgacheffe was once part of the Sidamo region but became an independent specialty region due to its distinctive flavor characteristics. The area has an average altitude of around 2,000 meters, with mountainous terrain and a cool climate, making it an ideal environment for cultivating Arabica coffee. Yirgacheffe encompasses several well-known micro-regions, such as Kochere, Guji, and Gedeb, each home to representative cooperatives producing beans with unique profiles. The Gedeb Gedebtindi Cooperative is one of them, standing out for its traditional washed processing and vibrant acidity.
The Gedeb Gedebtindi Cooperative is situated in the Worka area at the southeastern edge of Yirgacheffe and was originally part of the Worka Cooperative. With the global specialty coffee market placing increasing emphasis on “single-origin” and “traceability,” in 2012, Gedebtindi—comprising about 300 farmers—officially split from the original organization to become an independent cooperative. Gedebtindi Village was among the first to achieve independent operation. Most local farmers were former members of the Worka Cooperative, so their planting and processing techniques are solid, and they continue traditional washed and natural processing methods, earning the reputation as the “last pure land” of Yirgacheffe.
The coffee varieties used by the Gedeb Gedebtindi Cooperative are local native heirloom types, characterized by small bean size, typically ranging between 14 and 15 screens in size, with a relatively round appearance. Although Ethiopia has gradually begun classifying some varieties in recent years—for example, the Kurme variety, which stood out in the 13th COE competition—Gedebtindi still primarily uses traditional native varieties, showcasing the region’s unique flavor genetics.
In terms of processing, the Gedeb Gedebtindi Cooperative employs traditional washed processing with meticulous attention to detail. First, a pulper is used to remove the coffee cherry’s skin and pulp, after which the mucilage-covered parchment beans are placed in fermentation tanks for 18 to 36 hours of fermentation (the duration adjusted based on local temperature and humidity). Once fermentation is complete, the beans are washed in water channels for about 30 to 60 minutes, using water flow and channel design to remove lower-density defective beans. The high-quality parchment beans are then placed on African-style raised beds for approximately 14 days of sun drying. After drying, the beans are temporarily stored at the processing facility and, prior to export, sent to a dry mill for hulling, silver skin removal, foreign matter screening, and color sorting—among other intricate processes—to ensure optimal final export quality.
The coffee beans from the Gedeb Gedebtindi Cooperative are grown in the Gedeo Zone of Yirgacheffe, at altitudes between 1,900 and 2,300 meters, with native heirloom varieties and washed processing. For this acidity-forward bean, a light roast is recommended to preserve its clean mouthfeel, bright acidity, and pleasant aftertaste. During roasting, it is advised to use a Yangjia 800N roaster, with a charge weight of 480 grams, an initial drum temperature of 175°C, a fan speed of 3, and a heat setting of 120. As the beans turn yellow and grassy notes fade, gradually adjust the heat and fan speed, and carefully control the development time of 1’30” at first crack (around 9’38”), finally dropping the beans at 193.5°C to achieve the best flavor expression.
According to cupping records, the Gedeb Gedebtindi washed beans are evaluated within 8 to 24 hours post-roast, using 200ml ceramic cupping bowls, water at 94°C, a grind size of 70%-75% passing through a 20-mesh sieve, and a brew ratio of 1:18.18 (11 grams of coffee to 200 ml of water), with a concentration falling within the Golden Cup range of 1.15%-1.35%. During cupping, the dry aroma reveals the fresh acidity of passion fruit, citrus, and berries, while the wet aroma is dominated by citrus and berries. Upon tasting, one can perceive bright citrus acidity, berry sweetness, accompanied by layers of almond and tea notes, with a honey-like sweetness in the aftertaste. The overall body is light but clean and refreshing.
For pour-over brewing, it is recommended to use a V60 #01 filter, with water temperature controlled at 90-91°C, 15 grams of coffee, a brew ratio of 1:15, and a grind size of approximately 80% through a 20-mesh sieve (similar to the size of fine sugar). The suggested brewing steps are: begin with a 30-second bloom using 30 grams of water, followed by pouring 95 grams of water (totaling about 125 grams), taking roughly 1 minute, then when the water level drops to two-thirds of the coffee bed, pour another 100 grams of water (totaling about 225 grams), completing the pour in about 1 minute and 35 seconds. The total dripping time is approximately 2’10”, achieving the extraction. Under these parameters, the coffee exhibits flavors of citrus and black tea upon entry, with creamy, caramel, and almond notes emerging as the temperature changes, delivering a smooth and clean sweet taste overall.
