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.
