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.

Many coffee enthusiasts feel confused after getting coffee beans: which grinder setting should they actually use? In reality, the burr designs and setting standards of grinders from different brands vary greatly, and the same number on different devices can produce dramatically different particle sizes. Therefore, when Front Street Coffee performs daily grind calibration, it uses the Chinese No. 20 standard sieve (0.85 mm aperture) to measure the passing rate as a unified reference. This article will start with the specific steps for sieve calibration, combine different roast levels and brewing methods to give grinding recommendations, and share how to judge whether the grind is appropriate based on brewing time and the settling state of the coffee bed, helping you build a grind assessment system that does not rely on grinder settings.

This article will systematically sort out the key points of using a moka pot, from coffee bean selection and judging grind size to the complete brewing steps and cleaning and maintenance. At the same time, it will give specific recommendations based on several Front Street Coffee beans to help enthusiasts easily brew a rich and aromatic cup of moka pot coffee at home. [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…]

Common labels on coffee bean packaging such as light roast, medium roast, and cinnamon roast often confuse beginners. The roast level directly determines the direction of coffee flavor, and historically different countries and regions have had their own schools of thought for defining roast levels, lacking a unified standard. The Specialty Coffee Association of America, together with Agtron, used infrared caramelization measurement values as the basis to divide roast levels from light to dark into eight grades, which has become an important industry reference. In this article, Front Street will systematically introduce the Agtron color values, drop times, and flavor characteristics of each roast level, and share how to judge the roast level through flavor descriptions, as well as the grinding degree and water temperature parameters that should be used for different roast levels.

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…]

When making a proper espresso, choosing the grind size is often the most critical and most frustrating step. Unlike immersion brewing methods such as pour-over, an espresso machine relies on high temperature and high pressure to complete extraction in an extremely short time, which places demands on coffee grounds fineness and uniformity far beyond those of other brewing methods. If the particles are slightly too fine or too coarse, the flow rate can become abnormal, pushing the flavor toward over-extraction or under-extraction. This article will sort out the extraction principles of espresso from the ground up, explain the suitable grind fineness range, and provide a practical grinding adjustment process and flavor correction approach to help you quickly lock in the right grind setting even when facing unfamiliar beans.
