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…]

It also introduces the Sunflower Warm Sun blend used at Front Street Coffee locations, helping readers understand the beans and extraction logic behind a good espresso. [more…]

In the world of specialty coffee, the SCAA and COE are two authoritative systems that cannot be overlooked. The former established industry standards and cupping protocols, while the latter selects top-tier green beans through rigorous competitions. How do their scoring logics differ? And why are COE and SOE often confused? This article will trace the development and operational mechanisms of the SCAA, CQI, and COE, explain in detail the differences in cupping score sheets, and use the example of the 22nd-place sun-dried Typica that Front Street Coffee bid for at Ethiopia's first COE competition in 2020 to present the complete story from origin to cup.

The SCA recently published the latest rules and regulations for the 2024 World Barista Championship. Overall, the changes are not extensive; they mainly focus on further clarifying the wording regarding the judging process, conflict-of-interest declarations, and milk selection, while also adjusting the method for evaluating the tactile assessment of espresso.

This article will sort through the key points of the rule changes one by one to help readers quickly grasp the key adjustment directions of this year's WBC. [more…]

Latte art is the craft of a barista drawing patterns on the surface of an espresso with steamed milk foam. Does it actually change the taste and mouthfeel of a latte? This article analyzes the question from three angles: visual psychology, preparation technique, and quality of integration. Through comparative experiments, Front Street Coffee found that, provided the coffee beans, milk, extraction, and ratios are all on point, latte art and no latte art make no noticeable difference to taste—but latte art places higher demands on foam quality and evenness of integration. The article also explores the balance between pattern complexity, preparation time, and the drinking experience, helping enthusiasts view the relationship between latte art and flavor rationally.

Whether a coffee bean is worth buying repeatedly often depends not on how dramatic its flavor is, but on whether it can steadily become part of your daily routine. Roast level is a very practical starting point for judgment: light roasts highlight floral and fruity aromas and the interplay of acidity and sweetness, medium roasts emphasize balance and sweetness, while dark roasts are better suited for rich, smooth drinks. First, based on what you want in your cup [more…]

"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.

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. [more…]

Evaluating coffee beans suitable for long-term drinking is best approached by gradually building judgment from tasting experience. When buying beans for daily use, you need to consider how quickly you'll drink them, how much to buy at once, and whether you mainly make black coffee or milk coffee at home. The flavor words on the packaging can offer clues, but they cannot replace the actual drinking experience—whether the acidity is gentle, whether the sweetness lingers [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…]

The flavor quality of a latte is often decided by the choice of milk. There are many fresh milk brands on the market, with a wide price range, and their performance when paired with coffee varies. For home coffee enthusiasts, it is difficult to buy them one by one for comparison testing. This time, Front Street Coffee selected seven whole milk products that are common in coffee scenarios and relatively easy to buy, and conducted a comprehensive evaluation from low-temperature direct drinking, taste after heating, to the flavor, balance, and milk foam texture when making iced lattes and hot flat whites. There is no commercial promotion throughout, and the aim is to provide purchasing reference for readers with different taste preferences. This article does not set a final conclusion; the focus is on presenting the real performance of each milk to help everyone find the one that suits them. [more…]

Kenyan coffee has always been famous for its bright berry-like acidity, yet many early books recorded it as a dark roast, which is completely at odds with today's mainstream understanding. For this session, Front Street Coffee selected two high-altitude washed beans, Kenya Small Tomato and Karogoto, roasting both uniformly to the start of second crack, then conducting cupping, pour-over, and French press evaluations separately, and also attempting to blend them 1:1 with dark-roasted Mandheling into espresso. What kind of flavor transformation can a dark roast actually bring? Does it preserve a rich caramel character, or does it wipe out the original floral and fruity aromas? Using measured data and brewing parameters, this article takes you through a fresh look at the pros and cons of dark-roasted Kenya, as well as its unique value in blends. [more…]
