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…]

SCA Specialty Coffee Association technical officer Mario Fernandez revealed at an estate reception after the BOP Best of Panama competition that the SCA cupping form, which has been in use for more than two decades, is about to undergo a major reform. The current cupping form mixes discriminatory, descriptive, and emotional sensory judgments together, which easily leads to scoring bias. The new plan intends to separate the three and add evaluation items such as sweetness. At the same time, the coffee flavor wheel will also break free from its North America-centered limitations and compile a globally applicable flavor reference. In addition, SCA also plans to widen the score gap between specialty coffee and commercial coffee; a coffee scoring 80 points may in the future drop to 75 points or even lower. This article will sort out the background, direction, and specific contents of this reform for you. [more…]

During the pandemic, Starbucks employees in the United States and South Korea, facing issues such as understaffing, a mismatch between wages and workload, and a lack of safety guarantees, increasingly chose to form or join unions in an attempt to improve their situation through collective bargaining. From the birth of the first union in Buffalo, New York, to responses from employees in Chicago and South Korea, the discontent among Starbucks partners continued to simmer. Although the company remained indifferent and was even accused of failing to provide adequate pandemic support, employees continued to seek channels to make their voices heard. This article will sort out the ins and outs of the Starbucks employee union movement, as well as the wage, treatment, and working environment issues reflected behind it. [more…]

A proper espresso will have a delicate golden-brown foam floating on its surface, which Italians call Crema. It is the hallmark of espresso, yet it is often mistaken as the sole criterion for judging whether a coffee is good or bad. What exactly this layer of foam is and how it forms are worth discussing carefully. What is Crema? [more…]

Many pour-over enthusiasts habitually judge coffee quality by the shape of the coffee bed left in the dripper, believing that the deeper the bed, the better the taste. Is this belief correct? What can a deep bed actually tell us? In reality, the state of the coffee bed only reflects the uniformity of pouring and does not directly determine flavor. To produce an ideal coffee bed, uniform pouring alone is not enough—other conditions must also be met. This article will take a deep dive into the true relationship between the coffee bed and coffee taste, and share the complete set of factors that go into forming a perfect coffee bed. [more…]

During the blooming phase of pour-over coffee, whether the coffee bed can rise into a full "hamburger" shape is a phenomenon many enthusiasts pay attention to. Some brewers get a towering burger, while others end up with a flat or even sunken "steamed bun." The key behind this lies in the amount of carbon dioxide stored in the coffee beans and how efficiently it's released. The freshness of the beans, extraction parameters, and roast level all directly affect how much the bed expands during blooming. At the same time, the amount of oil on the bean surface is closely tied to roast level. This article will start from the principles of blooming, break down the factors that influence burger formation one by one, and explain how light and dark roasts perform differently during brewing, helping readers take a more rational view of the blooming puff-up phenomenon.

Latte art is a romantic expression of a barista's skill, with white milk foam blooming into heart or leaf patterns on the surface of dark brown espresso. Latte art is divided into two types: free-pour latte art and etched latte art created after pouring. The wonder of the former lies in the pattern forming simultaneously with the pour, while the latter offers a wider range of designs because the stable foam allows for leisurely drawing. From a physics perspective, the core of latte art lies in surfactants—molecules that possess both hydrophilic and hydrophobic groups, capable of stabilizing the interface between air and liquid to form lasting foam. Milk proteins and coffee lipids act together as surfactants, enabling the two micron-scale foams to remain clearly separated for a long time after mixing, thereby allowing the pattern to persist. This article will guide you from the basic principles of surfactants to understand espresso's crema, the formation of hot milk foam, and why foam mixing rather than liquid mixing is the key to successful latte art, while also revealing the widespread applications of surfactants in daily life and industry.

Many pour-over beginners don't run into clogging issues while brewing, yet after finishing, the coffee bed ends up perfectly flat, with no indentation at all. This shows that water flow control during extraction wasn't up to par, so a bowl-shaped bed couldn't form, which very easily leads to uneven extraction. Front Street has summarized three common mistakes: the bed wasn't lifted high enough, the water flow lacked enough stirring force, and the pouring circles were too wide in amplitude. We'll go through the causes one by one and give adjustment methods for each. Also, the depth of the coffee bed has no necessary connection to the roast level—whether you can produce a bed depression depends on your pouring technique, not how the beans were roasted, while the depth of the depression is determined by the dose of coffee.

As a globally popular beverage, coffee packaging must not only prevent the escape of aroma and moisture absorption, but also address oxidation, odor adsorption, and quality deterioration caused by high temperatures. This article focuses on the packaging needs of regular coffee and instant coffee, systematically outlining key technical requirements such as oxidation prevention, moisture resistance, gas barrier properties, and high-temperature protection, and introduces current mainstream vacuum packaging and gas-flushing packaging processes. In terms of material selection, bags, bag-in-box, metal cans, and glass jars each have corresponding composite structure solutions, while instant coffee mostly uses paper/aluminum foil/polyethylene flexible packaging. The article concludes with a summary of common packaging forms such as bags, cans, and boxes, suitable for reference by coffee enthusiasts and industry professionals. [more…]

Many coffee enthusiasts, when making latte art, most often encounter the problem of coarse milk foam that is not fine and smooth enough. In fact, the key to producing ideal dense milk foam lies in understanding how the steam wand works and how to create a stable vortex. This article will start with the principles of steam heating and foaming, gradually break down the core steps of air intake and texturing, and share practical tips for completing steaming and texturing at the same time. Front Street Coffee will also combine everyday operating experience to walk you through key points such as the angle of the milk pitcher, the position of the steam holes, and liquid surface control, so that you can easily recreate silky latte art foam at home.

Blooming is a key step in pour-over coffee brewing that cannot be overlooked, as it directly affects whether the subsequent hot water can evenly pass through the coffee bed. This article provides a detailed analysis of the difference between blooming and pre-infusion, explains the dual purpose of blooming—releasing carbon dioxide and forming an even filter layer—and offers specific recommendations for the amount of blooming water, typically 1 to 2 times the weight of the coffee grounds, along with the reason for keeping the water temperature between 85 and 92 degrees Celsius. At the same time, the article also explains the blooming pouring technique from three dimensions—small amount, even, and gentle—and points out the differences in water absorption among beans of different roast levels. Front Street Coffee reminds us that only sufficient and proper blooming can lay the foundation for subsequent even extraction, making the flavor of a cup of pour-over coffee more pleasant. [more…]

Many coffee enthusiasts have come across a claim online: after brewing with a siphon, if the coffee bed forms a small hill shape, it means the cup is of better quality. However, in practice, most people end up with a flat coffee bed. So how exactly can you get a siphon to produce a hill-shaped coffee bed? Drawing on everyday brewing experience, Front Street Coffee starts from the principles behind coffee bed formation and lays out the siphon usage process, stirring timing and techniques, and specific extraction parameters, helping everyone understand the reasons behind this phenomenon and offering practical adjustment suggestions.

Many coffee enthusiasts encounter a frustrating problem when practicing latte art: even though they follow the steps, a pattern simply refuses to form on the surface of the liquid. In fact, the essence of latte art is using the color contrast between milk foam and espresso crema to paint, and the key lies in precisely controlling the height of the milk pitcher and the flow rate during the integration stage and the pattern-forming stage. From the perspective of Front Street, this article systematically sorts out the three main reasons why latte art fails to produce a pattern—not shaking the milk evenly before integration, holding the milk pitcher too high when forming the pattern, and pouring with too small a flow rate—and provides corrective methods for each, helping you break through the bottleneck in your basic technique and successfully pour your ideal pattern.

People often say that traveling to Indonesia brought back rare "male beans" coffee, which is expensive and supposedly especially delicious. But are coffee beans really divided into male and female? The so-called male bean is actually Peaberry, also called round bean in Chinese; it and the common flat bean differ only in growth form, not in gender. The formation of peaberry is related to pests and diseases, drought, malnutrition, or the growth environment at the tips of branches, and botanically it is even classified as a defective bean. Some people think peaberry is mellow and sweet, while others regard it as a by-product with no commercial value. This article helps you clarify the true meanings of male bean, female bean, and PB, and introduces common peaberry coffees on the market, including Front Street Hawaii Kona Peaberry, Front Street Tanzania Peaberry, and Front Street Jamaica Blue Mountain Coffee Peaberry.

Today Front Street Coffee is here to share a new basic latte art pattern—the "leaf"! This time, the method for this leaf pattern is almost identical to the layered heart: both are formed by swinging the milk pitcher at a steady speed to create regular, symmetrical lines. If you've already mastered the layered heart, then the leaf is as good as in the bag too. Leaf. [more…]

After a pour-over coffee is finished, the state of the coffee bed often reveals whether the water pouring during the brewing process was standardized. An ideal coffee bed should be bowl-shaped, with an intact coffee wall of even thickness, but many coffee enthusiasts find that the coffee bed is "cut in the middle," split into upper and lower sections. How exactly does this faulting phenomenon occur? And what impact does it have on the flavor of the coffee? Starting from Front Street's practical experience, this article will analyze in detail the two causes of coffee bed faulting and provide two adjustment plans—narrowing the pouring range and reducing water flow intensity—to help everyone optimize their pouring technique and make extraction more even and complete.

In Starbucks' secret menu, the iced Americano with heavy cream, where the cream sinks to form white streaks, is called a Marble Americano. This way of drinking it originates from Con Panna and Viennese coffee. Luckin recently quietly launched three new drinks, one of which is precisely the Marble Americano, with promotional images that look quite appealing, attracting many consumers to try it early in the morning. However, the actual product differs noticeably from the promotion, with the cream in the coffee taking on forms like egg drop soup, tofu pudding, or spicy soup, and netizens jokingly calling it a bait-and-switch. This article sorts out the recipe differences, actual appearance, and taste feedback of this new product, and includes related recommendations from Front Street Coffee. [more…]

Many friends who are just getting into pour-over coffee go through a phase like this: standing in front of the coffee bar, eyes fixed on the barista's every move, trying to replicate a good cup of coffee by imitation. The grind size, the pouring rhythm, the number of circles, the total time—these visible "forms" are certainly important, but what truly determines the flavor of a cup of coffee is often the invisible extraction logic behind them. Drawing on Front Street Coffee's observations and experience, this article discusses just how important pour-over technique really is, and how beginners can start from zero, gradually moving from imitating movements to understanding parameters, completing the cognitive leap from "0" to "1."
