As an agricultural product, coffee beans' quality is influenced by many factors, so a grading system is needed to standardize quality and provide a purchasing reference for green bean buyers. Grading standards vary across producing regions: some are based on altitude, others on bean size, while Ethiopia uses a combination of defect rate and cupping. This article will provide an in-depth analysis of the meaning of the G1 and G2 grades for Ethiopian Sidamo coffee beans, explore the evolution of its grading system, and, through a comparison of Yirgacheffe G1 and G2—from appearance and roasting to cupping flavor—reveal the practical impact of grade differences on coffee quality.

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.
