How Does the Coffee Grading System Shape Yirgacheffe G1?

Worka's washed Yirgacheffe G1 shows jasmine, citrus, and stone fruit in the cup, and the grade itself is the reason. Beans ferment in washing tanks for about 72 hours, dry in the sun, and are hand-sorted before the Ethiopia Coffee and Tea Authority inspects them. Only lots that pass that check reach the export auction, so G1 marks the top tier of the region's coffee grading system.

The Yirgacheffe area produces roughly 225,000 bags of 60 kg each per year. Historically most went to Northern Europe, mainly Germany, and to Japan, while North American buyers have taken interest more recently. For brewing, use 15 g at a medium-fine grind, water at 90-92°C, a 1:15 ratio, and a total extraction time near 2:00.

The coffee beans undergo fermentation and demucilage in washing tanks for about 72 hours, after which they are directly sun-dried outside the facility. After manual sorting, the green beans must pass quality inspection by the Ethiopia Coffee and Tea Authority before qualifying, and are finally traded and exported through a bidding process. The region's annual output is about 225,000 bags (60 kg each).

The Worka cooperative has about 300 coffee farmers under it. YCFCU was founded in 2002, and its members also include 26 other cooperatives, serving more than 45,000 coffee farmers.

It is highly distinctive, outstanding, and very rarely seen.

In Ethiopia's coffee grading system, washed Grade 2 and sun-dried Grade 4 are the highest grades, so in the past the market only saw Yirgacheffe WP G2.
