We know that coffee bean grading methods are usually based on the actual conditions of the growing country. Some are graded by bean size, such as Kenyan coffee; some by altitude, such as Blue Mountain coffee; and some by defect rate, such as Ethiopian coffee. As the gene pool of Arabica, Ethiopia has a wide variety of coffee varieties. [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 inevitably varies in quality, so each producing region establishes a grading system to standardize quality and provide a reference for trading.

This article will systematically sort out the grading criteria for Yunnan coffee, the commonly used international and domestic standards, the varietal evolution of Arabica coffee, and introduce Front Street Coffee's experimental cultivation and product recommendations in Yunnan, finally attaching practical brewing parameters to give you a comprehensive understanding of the current state and charm of Yunnan specialty coffee.

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.

Coffee, as a plant of the Rubiaceae family, has over a hundred known species, but only three cultivated varieties are actually used for drinking: Arabica, Robusta, and Liberica. Among them, Arabica occupies about seventy percent of global production with its exceptional flavor and aroma, making it the top choice for single-origin and specialty coffee. From Ethiopia's native Typica and Bourbon to the Geisha that has swept the market today, Arabica subspecies are rich and diverse, each with its own characteristics. At the same time, origins such as Brazil, Colombia, Panama, Guatemala, Costa Rica, Jamaica, Ethiopia, Kenya, and Indonesia, by virtue of their unique terroir and processing methods, shape distinctly different coffee flavors. Front Street Coffee offers more than 50 different regional coffee beans in its stores, meeting diverse taste needs. This article will systematically sort out coffee variety classification, the advantages and disadvantages of Arabica, and representative global origins, taking you to gain a deeper understanding of the rich landscape of the coffee world.

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.

For many Manner baristas, the pay raise exam is the only path to a higher income, but the difficulty of this assessment is far beyond imagination. Manner stores are uniformly equipped with semi-automatic espresso machines, and examiners have standardized requirements for latte art, milk steaming, and grinder adjustment. As a brand focused on specialty coffee, it also adds a pour-over segment to the test. However, the actual pass rate is extremely low, with most candidates eliminated during the espresso operation stage. Unfamiliar store equipment, unfamiliar grinders, and nitpicky judging such as measuring milk foam thickness with a ruler make this exam seem impossibly hard. This article will restore the true face of the Manner pay raise exam and analyze the crux of why baristas fail repeatedly. [more…]
