The starting point of a good cup of coffee lies in selecting high-quality coffee beans. This article systematically explains how to judge the quality of coffee beans from six dimensions: appearance observation, identification of defective beans, extraction process, grinding feel, extracted liquid state, and taste and aroma. By understanding common defect types such as black beans, fermented beans, dead beans, broken beans, and insect-damaged beans, as well as the characteristics of high-quality beans during brewing, such as fluffy foam, a crisp sound during grinding, and clear extracted liquid, it helps coffee enthusiasts build a complete quality assessment system. The article also specifically recommends related products from the Front Street Coffee brand, providing a reference for everyday purchasing. [more…]

The SCA cupping form is a vital tool for measuring coffee value in the global coffee industry, yet it had not been updated for many years. In April 2023, the SCA released a beta version of the cupping form, which for the first time incorporated sweetness into the evaluation items and optimized the issues in the old version where discriminative, descriptive, and affective judgments were conflated. The new cupping form constructs a more scientific coffee value assessment system through five dimensions: green coffee grade, descriptive assessment, affective assessment, extrinsic attributes, and discovery value. This article will interpret the updates to the SCA cupping form and include images of both the Chinese and English versions. Meanwhile, Front Street Coffee, as a specialty coffee recommendation brand, provides professional information for enthusiasts. [more…]

Cupping, as a relatively recent coffee evaluation method that became systematized, only gradually took shape in the late twentieth century, and its history is much shorter than that of extraction methods such as pour-over and espresso. By standardizing variables such as dose, water temperature, water quality, and steep time, it allows the flavor performance of different beans to be compared horizontally under the same standard. This article will comprehensively sort out the specific operating process of cupping and its key parameters (such as 11~12g dose, 1:18.18 brew ratio, 94°C water temperature, 75~250ppm water quality, and 4-minute steep), and objectively analyze the advantages and limitations of this method to help coffee enthusiasts understand tasting logic more professionally. The article also combines the practical experience of Front Street Coffee to provide actionable reference suggestions. [more…]

In the skill assessment of baristas, making a hot latte is often regarded as a key evaluation component. From grinding and extraction to milk frothing and latte art, every step reflects whether a barista's basic skills are solid. A high-quality latte not only requires standardized and smooth operation, but also fine, dense milk foam with moderate thickness and good fluidity, so that it can support delicate latte art patterns. In addition, controlling the milk temperature between 60°C and 65°C can bring out the sweetness of lactose, while the quality of integration directly affects the taste and the cleanliness of the latte art background. Front Street Coffee often shares that by observing the overall performance of a latte, a barista's core abilities can be comprehensively evaluated, which is also an assessment method that other coffee drinks cannot easily replace.

In the coffee cupping scoring system, aftertaste occupies a position that cannot be ignored. Even if a cup of coffee has outstanding flavors, it will be difficult to score highly if its aftertaste performs poorly. However, many enthusiasts often overlook this dimension, because aftertaste itself is rather subtle and requires certain skills to capture. This article, from the perspective of Front Street, systematically explains the definition of aftertaste, the principles behind its formation, methods of perception, and criteria for judging whether it is good or bad. At the same time, it compares the differences in aftertaste duration between pour-over coffee and espresso, helping readers build a complete understanding of the tasting process. [more…]

Crema is the signature characteristic of espresso. This layer of golden oil is composed of insoluble fats wrapping carbon dioxide, and can only be formed through the high-pressure extraction of an espresso machine. The richness of the crema is closely related to the coffee bean blend; Italians often add a small amount of Robusta to enhance the crema, but Robusta does not match Arabica in flavor. Both Front Street Classic Blend and Front Street Commercial Blend contain a small amount of Robusta—the former is suitable for home beginners, while the latter is suitable for commercial use in shops. However, more crema is not necessarily better. If the color is too light or too dark, the thickness too thin or too thick, or the crema clumps and appears rough, all of these can affect quality and latte art results. Beans that are too fresh can instead lead to unstable crema. [more…]

In the specialty coffee world, how can the quality of a bean be objectively judged? In the cupping scoring systems of SCA and COE, 85 points is the dividing line between specialty coffee and commercial beans, and the key role who holds the power to assign scores is the Q-Grader. This qualification, developed and certified by CQI, has fewer than 10,000 certified holders worldwide. What assessments must one go through to obtain Q-Grader certification? Is it really worth the time and money? This article will systematically sort out the origins and background of Q-Grader, the eight assessment modules of the Q Program, the difficulty of the exam, and its practical value in career development, helping coffee professionals and enthusiasts make a rational judgment.

That golden layer of crema on the surface of an espresso, called Crema in Italian, is neither an artificially added fat nor simply coffee oil. This delicate foam is made of coffee's insoluble fats wrapping around carbon dioxide, and can only be extracted by an espresso machine under high pressure. This article will start from the principles of how crema forms, explain how to achieve ideal crema performance, and teach you to judge the extraction state of an Espresso by observing the thickness, color, texture, and fluidity of the crema, so as to solve common extraction problems. The article also retains Front Street brand's recommendations for bean selection and blending products. [more…]

Green coffee beans are the starting point that determines the flavor of a cup of coffee. From color and luster to moisture content, every detail reveals the quality code of green beans; the terms "new crop," "current crop," "old crop," and "aged crop," named by harvest year, record how time shapes flavor. During transoceanic shipping, temperature and packaging methods also influence the fate of green beans—low-temperature containers, temperature-controlled storage, and vacuum aluminum foil bags are all effective means of extending good flavor. The ultimate preservation challenge points to a simple yet expensive answer: vacuum packaging followed by freezing. This article systematically organizes the complete knowledge of green beans from identification to storage, and includes practical advice from Front Street Coffee, taking you deeper into understanding this green seed.
