Introduction:Delve into the origin characteristics, processing methods, and SCAA grading system of Ethiopian Yirgacheffe Aricha G1 washed coffee beans, and master the unique flavor profile of this high-altitude heirloom variety. This article provides professional pour over recommendations and tested parameters to help you fully showcase Aricha G1’s citrus, honey, and red berry layers—from roast level and grind size to water temperature control.
Yirgacheffe, as Ethiopia’s most iconic specialty coffee region, is renowned for its distinctive citrus notes and floral-fruit aromas, and the Aricha G1 washed batch is a classic favorite among many coffee enthusiasts. This article not only explains the SCAA grading logic for both washed and natural processed Ethiopian coffees in detail but also introduces the Aricha G1 growing region, the background of the processing mill, and how Project Origin enhances coffee farmers’ income and bean quality through direct trade.
In terms of grading, the SCAA has established two main grades—Gr-1 and Gr-2—for washed Ethiopian coffee beans, with the lower number indicating higher quality. Aricha G1 belongs to the top washed grade, often exhibiting clear citrus and cherry aromas, along with bright acidity and honey-like sweetness. In contrast, naturally processed Yirgacheffe is categorized into Gr-1, Gr-3, Gr-4, and Gr-5, where Gr-1 naturals typically showcase intense tropical fruit profiles, and the aroma upon opening the bag often defies conventional expectations of coffee.
Aricha G1 comes from the Gediyo micro-region within Yirgacheffe, at an altitude of 1900 to 2100 meters. It is cultivated by approximately 650 to 700 smallholder coffee farmers and processed centrally at the Kebel Aricha mill. These heirloom coffee trees grow in high-altitude mountainous areas, and the slow maturation process imparts richer flavors and higher acidity to the beans.
During processing, farmers first harvest fully ripe coffee cherries and place them in water tanks for flotation. Since cherries of varying ripeness have different densities, unripe or overripe ones float to the surface and are removed, while only those that sink to the bottom proceed to the next stage. The cherries are then depulped by a pulper to remove the outer skin, and the mucilage-covered beans enter fermentation tanks, where natural microbes break down the remaining pulp. Fermentation time and environmental conditions are strictly controlled to ensure flavor purity.
After fermentation, the green beans are thoroughly rinsed with clean water to remove any surface residues, then spread out on African beds to dry in the sun. This stage requires precise maintenance of the beans’ moisture content at around 12%, taking about two to three weeks. The dried beans are then stored for 2 to 3 months for “resting” to stabilize the flavors, after which the parchment layer is removed, resulting in the green beans we see.
Project Origin is an initiative launched by 2015 World Barista Champion Sasa Sestic and his team, aiming to collaborate directly with coffee farmers in developing countries. It offers purchase terms that are 20% higher than fair trade prices and improves their planting and processing techniques. The program has expanded to eight countries, including Brazil, Panama, Ethiopia, and Costa Rica, strengthening the connection between roasters and producers and ensuring transparency and traceability in every step from planting to cupping.
In terms of flavor profile, this Aricha G1 washed bean exhibits bright traits such as sweet orange, cherry, and honeyed sweetness, along with complex fruit aromas of green berries, peaches, longan, and red dates. The finish unfolds layers of cocoa and subtle spicy notes, with a full body and lingering aftertaste. It is ideal for pour over lovers who enjoy bright acidity and fruity profiles.
Recommended practical pour over parameters are as follows: Use 15 grams of medium-fine grind (approximately 3.5 on the Hario Mini Mill/Micro/Mk2 or similar, akin to 3.5 on a Fuji Crema sharp burr), paired with a V60 filter. Water temperature should be controlled at 91–93°C. The first step is to pour 30 grams of water for a 27-second bloom, then continue pouring up to 105 grams before stopping. Once the bed level drops halfway, resume pouring, with a total recommended water volume of 225 grams and a brew ratio of about 1:15. Total extraction time is approximately 2 minutes. Be mindful to allow some fines to settle at the end to ensure a cleaner cup.
