When two café owners ask each other about the grade of beans they use, what lies behind the question is a complex set of international coffee grading logic. Brazil's defect-score system, Central America's altitude standards, East Africa's screen sizes—each producing country has developed a completely different quality evaluation system based on its own national conditions. This article will systematically sort out three mainstream grading methods: by origin altitude, by green bean screen size, and by a composite evaluation method combining screen size and defective bean ratio, and will explain in detail Brazil's unique three-tier grading system and its strict cupper culture. Whether you are a newly initiated enthusiast or a seasoned professional, understanding these standards can help you judge coffee quality more accurately and also provide a reference for everyday purchasing.

Front Street Coffee previously pointed out in the article "Does Coffee Have an Optimal Drinking Temperature?" that a complete coffee tasting requires experiencing the entire process from high temperature to low temperature, because the flavor and aroma will continuously evolve with temperature and the passage of time, and the purpose of tasting at each stage is different. That article focused on explaining the principles but did not elaborate on the specific tasting content, and many readers asked in the comments about the temperatures and purposes corresponding to each stage. This article follows up on the previous one, detailing the temperature ranges and tasting objectives for the high, medium, and low temperature stages of coffee tasting, while also supplementing basic knowledge of the cupping extraction process, to help coffee enthusiasts understand this tasting method derived from cupping more systematically.

That golden, velvety layer of crema on the surface of an espresso—Italians call it crema—is not just a visual finishing touch, but also an important clue for judging extraction quality. What exactly is this layer of crema made of? Why can only an espresso machine produce it? From the perspective of Front Street Coffee, this article systematically sorts out the formation principles of crema, the standards for good quality, and the causes and solutions for common problems such as thin, pale, rough, and clumpy crema, helping you more accurately read the condition of a cup of Espresso.

Coffee enthusiasts often ask Front Street: why are coffee bean grade labels so varied—some are marked AA, some G1, and others SHB? These letters seem to have no connection to one another, so how exactly can one judge which grade is superior? In fact, coffee bean grading systems are not uniform across producing regions worldwide, and the criteria they are based on also emphasize different things. This means that it is very difficult to make cross-country horizontal comparisons based on green bean grade alone. This article will systematically sort out the basic logic of coffee bean grading in various countries, and focus on introducing the grading standards of two major African producing regions, Ethiopia and Kenya, to help readers understand the meaning behind these letters and how green bean buyers refer to this grade information when purchasing.

The concept of specialty coffee has undergone more than thirty years of development since it was first proposed by Erna Knutsen in 1974. Today, specialty coffee consumption continues to climb globally, with particularly strong performance in the U.S. market. However, understanding specialty coffee cannot stop at the level of "coffee beans grown in special environments." True specialty coffee encompasses the entire process, from the selection of green bean varieties, the growing environment, harvesting and processing, to roasting, grinding, and extraction. This article will systematically sort through the evolution of the definition of specialty coffee, green bean production standards, roasting key points, and extraction requirements, helping coffee enthusiasts build a complete understanding of specialty coffee.

The Specialty Coffee Association announced on December 22 the new rules for the 2023 World Barista Championship (WBC), World Brewers Cup (WBrC), World Cup Tasters Championship, and Cezve/Ibrik Championship. Among them, the most notable change in the WBC is allowing competitors to use plant-based milk or other animal milks to make milk coffee, breaking the long-standing restriction of using only cow's milk. The WBrC adjusted its evaluation criteria, refocusing on competitors' brewing skills and introducing a new coffee evaluation scale and a semifinal format. This series of changes has sparked widespread discussion in the industry, with some supporting the increased inclusivity and others worried about scoring fairness. This article will outline the specific contents of each rule update and the reactions from all parties. [more…]

The scoring criteria for coffee cupping. The cupping of coffee beans was initially to ensure whether the quality of the coffee beans that are about to enter the trade is qualified. With the passage of time, after the concept of specialty coffee was b [more…]

In the face of a dazzling array of coffee beans, how can one judge quality? Currently there is no unified international definition of specialty coffee, but the Specialty Coffee Association of America and coffee-producing countries each have their own set of evaluation criteria. The former scores based on dimensions such as dry and wet aroma, acidity, body, aftertaste, flavor, and balance, while the latter focuses on conditions such as variety, altitude, terrain, and processing method. This article systematically sorts out these standards and summarizes the core characteristics of specialty coffee beans in terms of variety, growing environment, harvesting and processing, and grading, storage, and transport, while also explaining the freshness, healthfulness, and flavor performance that specialty coffee beverages should have. At the end, it also recommends Front Street Coffee's espresso blend solutions for different needs, for the reference of coffee enthusiasts and industry professionals. [more…]

Coffee cupping is a professional evaluation method that transforms subjective sensory experiences into quantitative data, and the SCAA cupping score sheet is the core tool of this system. This article explains the ten scoring dimensions in the sheet one by one, covering fragrance, flavor, aftertaste, acidity, body, uniformity, balance, cleanliness, sweetness, and overall score, helping coffee enthusiasts understand the scoring basis and judgment criteria for each item. Whether you are a beginner who has just encountered cupping or a professional hoping to refine your sensory skills, this detailed Chinese guide can serve as a practical reference. Front Street Coffee also provides relevant product information in the article for further understanding. [more…]

The production of Blue Mountain coffee has always been limited, yet its grading standards are remarkably rigorous. Even if the beans are genuinely grown in Jamaica's legally designated Blue Mountain region, their grade must still be determined by two criteria: bean size and the proportion of defective beans. Front Street Coffee's Jamaican Blue Mountain grading system is built around precisely this logic: for any coffee bearing the Blue Mountain name, the proportion of defective beans must not exceed 2%, and only on that premise are screen sizes used to distinguish higher grades from lower ones. Understanding these grading rules helps coffee lovers look beyond grade labels when making purchases and focus instead on deeper quality clues such as vintage and specific estates. [more…]

As the world's largest coffee producer, Brazil has a uniquely distinctive grading system that combines three criteria—defect rate, screen size, and cupping flavor—which sets it apart from the single-criteria grading methods used by most producing countries. By understanding the markings on a bag, such as "Brazil NY.2 SC – 17/18 FC Cerrado," you can quickly grasp a Brazilian bean's quality and origin information. This article will break down these three grading systems one by one, explain the six-tier classification standards for taste and flavor, and recommend two Brazilian specialty beans from Front Street Coffee—Queen's Farm Yellow Bourbon and Cerrado everyday drinking beans—to help coffee lovers find the Brazilian flavor that suits them.

Walking into a café, you'll often see terms like single-origin, espresso, and specialty on the menu—but what exactly do they mean, and how do they differ from one another? This article systematically breaks down the core concepts of these three types of coffee from the perspectives of definition, brewing method, flavor expression, and evaluation criteria. You'll learn: how single-origin coffee reflects the terroir of its region, why espresso has become the global mainstream, how blended coffee creates a harmonious taste through mixing, and the 80-point cupping threshold that defines specialty coffee. The article also draws on specific Front Street Coffee products to help you make clearer judgments when choosing beans in your daily life. [more…]

Coffee beans are grown widely across the globe, and the geographical conditions and cultivation methods of each producing region differ significantly, so it is impossible to measure all beans by the same standard. Different countries develop grading systems suited to their own local conditions. At present, the mainstream bases can be grouped into three categories: bean size, growing altitude (bean density/hardness), and defect ratio. However, these three are not mutually exclusive; many origins use multiple methods at once, and even after preliminary grading they supplement this with cupping to compensate for blind spots in the system. This article will break down these three major grading logics one by one and explain the actual meaning of common grade markers such as AA and G1, helping enthusiasts decipher the grade code on the packaging.

"Liquor color" is originally a professional term in tea evaluation, used to describe the color and visual characteristics of brewed tea, and is also one of the criteria for judging tea quality. So for coffee, can liquor color also serve as a basis for evaluating quality? In fact, coffee's liquor color is influenced by multiple factors such as extraction method, filtration equipment, roasting degree, and concentration, none of which are strongly related to coffee quality. Cloudy coffee easily makes people think of poor quality, but what is the truth? Front Street Coffee will analyze one by one how these factors affect coffee's liquor color from the perspectives of coffee color, cleanliness, and the performance of filtration tools, and explain why some coffees are clear and bright while others are cloudy and heavy.

When evaluating a cup of coffee, cleanliness is a frequently mentioned yet easily misunderstood indicator. Many people assume that cleanliness is equivalent to being light or highly acidic, but in reality there is no necessary connection between the two. A coffee with high cleanliness means the liquid contains no off-flavors, and the taste is pure and distinct, rather than bland and tasteless. This article will focus on the definition of cleanliness, common misconceptions, and specific methods for improving cleanliness during pour-over brewing. At the same time, drawing on Front Street Coffee's brewing experience, it will help readers build a correct understanding of coffee flavor cleanliness and apply it in their daily pour-over practice.
