Ethiopia, as the genetic treasure trove of Arabica coffee, has a unique green bean grading system. Unlike Kenya, which grades by bean size, or Blue Mountain, which grades by altitude, Ethiopia primarily classifies grades based on defect rates and cupping scores. This article will systematically sort out the evolution of Ethiopia's old and new grading systems, provide an in-depth analysis of the specific standards for grades G1 through G9, and, using Yirgacheffe as an example, compare the actual differences between washed G1 and G2 in green bean appearance and flavor performance.

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.
