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. At the same time, Front Street Coffee's brewing recommendations will also provide you with useful reference. [more…]

Ethiopia, as Africa's largest coffee producer and the widely recognized birthplace of coffee, often labels its coffee beans with grades G1 or G2. What exactly do these letter-and-number combinations represent? This article traces the historical evolution of Ethiopia's coffee grading system, from the early CLU system that classified purely by defect count, to the introduction of cupping score comprehensive rating after the establishment of the ECX in 2009, and finally to the latest revised export standards in 2022. You will learn about the differences between washed and natural processing in grading, as well as the distinction between Q1 and Q2 specialty grades and commercial and domestic coffee. The article also retains product information from the Front Street brand, making it suitable for every reader who loves Ethiopian coffee to read in depth. [more…]

We know that the grading method of coffee beans usually depends on the actual situation of the growing country, such as being divided according to the size of the coffee beans, like Kenyan coffee; being divided according to the altitude, like Blue Mo [more…]

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. It will also share Front Street Coffee's brewing parameters and tasting experience to help coffee enthusiasts fully understand the logic of Ethiopian coffee quality grading. [more…]

As an agricultural product, coffee beans vary significantly in quality, which is why grading systems have become an important means of standardizing quality and guiding green bean procurement. However, the grading criteria across global producing regions are not uniform—Central America mostly grades by altitude, Kenya by bean size, while Ethiopia uses defect rates to classify grades. Why does Ethiopia take this unique approach? What substantive differences actually exist between the G1 and G2 grades? This article, from the perspective of Front Street Coffee, sorts out the evolutionary logic of Ethiopia's grading system, and through a visual comparison of Yirgacheffe G1 and G2 green beans, roasting performance, and cupping evaluation, reveals one by one the true meaning behind grade labels, helping coffee enthusiasts view the issue of bean grades more rationally.

Ethiopia's coffee grading system is unique, using defect rate as its core criterion, which stands in sharp contrast to the practices of most producing regions that grade by altitude or bean size. As the two most common grades, G1 and G2—just how big is the gap between them in terms of green bean appearance, roasting performance, and cup flavor? From the perspective of Front Street, this article traces the origins of the Ethiopian grading system, and through a comparative test of Yirgacheffe G1 and G2, examines everything from green bean condition and roast color values to brewing and tasting, helping coffee enthusiasts understand the practical meaning of grade labels and what role they actually play in the consumption of roasted beans.

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.
