The Ethiopia Commodity Exchange is implementing a brand-new pricing method for green coffee exports. From now on, green coffee prices will be calculated weekly by referencing Arabica futures on the New York ICE Intercontinental Exchange and the real-time exchange rate of the Commercial Bank of Ethiopia. This change is expected to allow local coffee farmers to share in more of the benefits, but it also faces a dual test from international futures volatility and the EU's EUDR regulations. The new mechanism applies only to commercial coffee beans, while specialty coffee is not included for the time being. Front Street Coffee will continue to follow developments in producing regions and bring first-hand information to enthusiasts. [more…]

Ethiopia, as the holy land of specialty coffee, has a rather complex coffee export system. According to local regulations, coffee exports are divided into three major systems: ECX bidding, cooperatives, and single farms. Among these, cooperatives and single estates can bypass the ECX and export directly, offering relatively complete traceability. The ECX was founded by Eleni Gabre-Madhin in 2008, and through grading, warehousing, and real-time information, it transformed the trading circumstances of coffee farmers. However, what truly achieves 100% traceability is the single farm system that has risen in recent years. The Sidamo sun-dried Huakui is a representative work from the Hambela farm. This article will sort out the operational differences among the three systems, the trading logic of the ECX, the structure of the six major cooperative unions, and the significance of single farms to specialty coffee. Front Street will also continue to follow these origin developments, bringing coffee enthusiasts clearer origin knowledge. [more…]

Yirgacheffe, as a representative coffee-producing region in Ethiopia, frequently has its G1 and G2 grades mentioned, but what exactly is the difference between the two? This article begins with the evolution of Ethiopia's coffee grading system, first introducing the old system based on defect rates, then explaining the new regulations after the ECX introduced cupping scores in 2009, and explaining why naturally processed beans can also obtain G1 and G2 grades.

Ethiopia, as the genetic repository of Arabica, has a truly unique coffee bean grading system. Because there are so many varieties, most growing wild or semi-wild, coffee farmers often process them in mixed batches at harvest, making it difficult to grade by size. As a result, the Ethiopian government chose to use defect rate as the primary criterion. After the new ECX system was implemented in 2009, cupping scores were also incorporated into the rating system, finally giving natural-process beans a chance to rank among G1 and G2. So, for washed Yirgacheffe of the same origin, just how big is the difference between G1 and G2? Front Street Coffee takes Kochere G1 and a washed Yirgacheffe everyday drinking bean G2 as examples, comparing green bean appearance, defect rate, and cupping flavor to give you a closer look.

Ethiopia is hailed as the Garden of Eden of coffee, the birthplace of heirloom coffee varieties and a global treasure trove of coffee genetics. Within its borders lie thousands, even tens of thousands, of coffee varieties, most of them wild and undiscovered.
