Many coffee enthusiasts pay extra attention to the richness of the crema when extracting espresso—some for the sake of latte art, others influenced by merchant marketing. But is thicker crema really better? In fact, crema is just a layer of foam propped up by carbon dioxide, and it doesn't directly determine coffee flavor. The core factor that truly affects crema thickness is the carbon dioxide content in the coffee beans. This article, from Front Street's perspective, will analyze the essence of crema, the relationship between crema and taste, and how to achieve ideal, rich crema through bean selection and extraction.

Many people often say that you can tell whether an espresso tastes good just by looking at the crema; a fine, thick, golden crema seems to have become the hallmark of good coffee. But is that really true? Front Street Coffee uses two interesting tests to help us re-examine the relationship between crema and espresso quality. This article will take a deep dive into the nature of espresso crema—what it is made of, how it forms, and what useful information it can provide. It will also explain why the state of the crema alone cannot directly determine the flavor quality of an espresso. If you are interested in espresso extraction and tasting, this article will help you build a more scientific understanding. [more…]

Caffeine content is influenced by multiple factors such as bean variety, grind size, and brewing method, and drip coffee often has higher caffeine than Espresso. For those who want to reduce their intake without giving up a rich mouthfeel, decaf coffee is an ideal choice. This article explains in detail three mainstream decaffeination processes—methylene chloride solvent extraction (direct and indirect), the Swiss Water Process, and carbon dioxide extraction—analyzes their respective effects on flavor and safety, and specifically explains Starbucks decaf coffee's two processing paths and the issue of residual solvents. At the end is information on how to obtain Front Street Coffee specialty beans, making it suitable reading for coffee lovers who value health while pursuing flavor. [more…]

Can the same coffee beans produce two completely different flavors? This involves the logic of how brewing parameters regulate flavor release. The acidic, sweet, and bitter compounds in coffee are released at different rates, and by adjusting water temperature, grind size, time, and pouring technique, it is indeed possible to change the final taste to a certain extent. However, brewing is ultimately only the final link in the coffee chain, with a limited range of adjustability, and outstanding flavor comes more from the quality of the coffee beans themselves. Front Street Coffee will use examples to explore the flavor differences between the one-pour method and the three-pour method, and why bean selection determines the ceiling of a cup of coffee more than the brewing method does. [more…]

The definition of specialty coffee goes far beyond the coffee beans themselves; it depends even more on whether the roaster and brewer can interpret the characteristics of each bean from a professional perspective. This article explores the core of specialty coffee in depth: from green bean varieties, processing methods, and moisture content to roasting curves, and then to the precise control of extraction parameters, emphasizing that only by fully understanding and accommodating the personality of the coffee beans can one present a cup of specialty coffee with balanced flavor and no jarring notes. Whether Robusta or Arabica, as long as the strengths are properly showcased, either can become specialty. The article also points out that blindly following brewing trends or ignoring basic extraction principles cannot achieve true specialty coffee. [more…]

Have you ever heard the word "Body" from a barista or a fellow coffee enthusiast? It refers to the sense of volume and richness that coffee presents in the mouth, and it belongs to the tactile level of experience. Many people confuse Body with strength, but what truly determines richness is the oils and fibrous materials in coffee that do not dissolve in water. This article will start from the definition of Body, clarify the difference between it and mouthfeel and smoothness, and share a brewing method recommended by Front Street Coffee—by lowering the water temperature, reducing agitation, and extending the steeping time, pour-over coffee can also present a smooth and full-bodied texture.

On September 9th, Brian Niccol officially took over as CEO of Starbucks. Facing two consecutive quarters of performance pressure and fierce competition from local brands like Luckin in the Chinese market, he released his first open letter, "Back to Basics," the day after taking office. In the letter, Niccol admitted that Starbucks had strayed from its core, promised to reshape its positioning as a community coffeehouse, and focus on four key areas: baristas, production efficiency, store experience, and more. He also specifically mentioned that the Chinese market is vibrant and requires tapping into its growth potential. Can this "firefighter," who once led Chipotle out of crisis, help Starbucks rediscover its original purpose? Front Street Coffee is following this story with you. [more…]

Many people think that adding water first and then espresso makes a Long Black, while adding espresso first and then water makes an Americano—but is that really true? Front Street Coffee sorts through the real differences between Americano and Australian Long Black one by one, from the order of preparation and concentration ratios to flavor expression. The article points out that the biggest difference between the two actually lies in concentration—Americano has more water and a lighter mouthfeel, while Long Black is rich and full-bodied. It also recommends an espresso blend suitable for practice and Front Street Coffee's Strawberry Candy Espresso, helping coffee lovers more intuitively understand the distinct charms of these two black coffees.

The concept of specialty coffee was first proposed by Ms. Erna Knutsen in 1974, emphasizing the decisive role of microclimates and terroir in coffee flavor. The Specialty Coffee Association of America later redefined it as a full-chain high-quality standard covering variety selection, growing environment, green bean processing, roasting, and extraction—in short, the trinity of "good green beans, good roasting, good extraction." Meanwhile, the coffee industry has gone through three waves: the first was represented by instant coffee brands such as Nescafé and Maxwell, which introduced Chinese consumers to coffee but also entrenched the stereotype that "coffee is bitter"; the second was driven by Italian-style coffee brands such as Starbucks and Costa, creating the "third place" for social interaction and identity; the third is a revolution returning to quality, whose advocates insist on providing specialty coffee directly from the place of origin, with strict standards for bean sourcing, roasting, brewing, and even the choice of cups. Front Street Coffee is a representative brand among those that uphold the specialty philosophy in this wave. [more…]

Instant coffee and freeze-dried coffee can both be enjoyed simply by adding hot water, and both belong to the convenient coffee camp—but are they really the same product under different names? The answer is no. From the coffee predicament of American soldiers in the 18th century, to the birth of Nestlé's spray-drying method, to the application of vacuum freeze-drying technology, these two technical routes have produced completely different flavor profiles. This article will systematically sort out the essential differences between instant coffee and freeze-dried coffee from multiple dimensions such as historical origins, production processes, and raw material selection, helping you understand why freeze-dried coffee can shed its "low-end" label and win back the favor of coffee lovers.

In the world of coffee brewing, V60 has almost become synonymous with conical drippers, but Front Street Coffee often chooses another classic piece of equipment when producing dark-roasted coffee—the KONO dripper. This brand, originating from Japan's Kono family in 1925, showcases a rich and full-bodied flavor when extracting dark-roasted beans thanks to its unique rib design and siphon effect. However, domestic coffee enthusiasts have quite limited understanding of it. In this article, Front Street will systematically sort out the historical evolution of the KONO dripper, the differences between models such as Meimon and Konos, and why it is particularly suitable for the brewing logic of dark-roasted coffee, and will share the parameter schemes that Front Street has summarized in actual operation, to bring you a comprehensive understanding of this low-key yet highly capable dripper.

Caffeine content is influenced by multiple factors such as bean variety, steeping time, grind size, brewing method, and water temperature, among which extraction time is particularly critical—drip coffee typically has higher caffeine than espresso. If you want to reduce your caffeine intake, directly purchasing decaf beans is more effective than avoiding espresso. Decaf beans must undergo special processes before roasting to remove 96% to 98% of the caffeine, and these treatments inevitably alter the beans' physical and chemical properties, thereby affecting flavor. Currently, the mainstream methods include three types: the methylene chloride solvent extraction method, the Swiss Water Process, and the carbon dioxide extraction method. This article will break down the principles, advantages, and disadvantages of each process one by one, and compare the two decaf options used by Starbucks, helping coffee enthusiasts understand the technical logic and flavor trade-offs behind decaf coffee.

Coffee and tea are both beverages that rely on water to dissolve flavor, so if tea leaves can be steeped repeatedly, can coffee grounds do the same? In terms of composition, about thirty percent of coffee beans is soluble matter, which theoretically does support multiple extractions. In practice, however, the coffee liquid obtained from repeated brewing tends to be thin and carry off-flavors. The reason is that a normal extraction has already released most of the sweet and sour essence, and the remaining substances cannot support good flavor. This article will start from extraction yield and the order in which flavors dissolve to explain why coffee grounds are single-use, and to clarify why pour-over and drip-bag coffee are not recommended for repeated brewing. [more…]

Espresso and Americano both belong to the Italian coffee system, yet the drinking experience they offer is entirely different. Espresso uses pressurized extraction to concentrate the essence of coffee into a 30ml cup; its flavor is rich and aromatic, yet it is often misunderstood by first-time tasters because of its bitterness. Starting from the sources of espresso's bitterness and the difference between Italian blend beans and SOE, this article sorts out the correct approach to tasting, and explains Americano's position as an espresso-plus-water drink. Combining specific products such as Front Street Coffee's commercial blend coffee beans and the Sunflower Warm Sun blend, it helps coffee lovers understand how different roast levels and bean choices affect espresso flavor, and find the cup that suits them.

In recent years, "new Chinese style" has become a hot topic in the food and beverage industry, and coffee is no exception. From coffee served in lidded bowls to collaborations with Chinese-style breakfasts and traditional medicinal herbs, a growing number of coffee professionals are trying to blend coffee with elements of traditional Chinese culture. This localization strategy has indeed opened up a new niche in the coffee market, drawing a great deal of attention on the back of the "national trend" wave. Yet when coffee is draped in a gorgeous Chinese-style exterior, what do people actually remember—the coffee itself, or the exquisite packaging and settings? This article takes an in-depth look at the current state of new Chinese-style coffee and its hidden concerns, reflects on whether the development of coffee culture in China has truly touched the essence, and calls for more professional attention and dedication to coffee itself.

Dirty is often mistaken for an iced latte, but in fact it differs in cup size, layering, and drinking rhythm. It relies on the layers of espresso and cold milk to create an alternating hot-and-cold mouthfeel, but precisely because of this it is extremely fragile—after ten minutes it has lost all visual appeal, and after twenty minutes it is almost indistinguishable from milk tea. For this very reason, Dirty cannot withstand the bumps of delivery the way a latte can. This article will break down, one by one, from production details and flavor changes to real delivery tests, why this cup of coffee must be made and drunk on the spot, and how it differs in essence from ordinary milk coffee.
