In Ginza, Tokyo, there is a long-established high-end coffee shop founded in 1948—Café de L'Ambre, famous for its founder Ichiro Sekiguchi's ultimate pursuit of coffee quality. But compared to the shop itself, its original drink "Amber Queen" actually enjoys greater fame. This coffee has sweetened cooled black coffee on the bottom layer, with unsweetened condensed milk floating on top; one sip lets you experience the dual flavor of coffee and milky aroma at the same time, and the visual effect is also extremely soothing. Many enthusiasts try to recreate it at home, but often encounter the problem of the condensed milk sinking and being unable to form layers. This article will share the complete method for making Amber Queen, from explaining the principles to the brewing steps, to help everyone make a cup of this classic Japanese-style coffee drink with distinct layers.

Many friends who are just getting into pour-over coffee often hold an almost worshipful attitude toward the expansion of the coffee bed and the deep pit, believing that producing a deep pit signifies superior skill. Front Street found this phenomenon to be quite common when talking with customers in the shop, so we decided to analyze the conditions for the formation of the deep pit from a fundamental perspective. In fact, the deep pit is mainly related to three factors: the roast level of the coffee beans, the circular pouring pattern, and the dose of grounds, with roast level having the most significant influence. Dark-roasted beans have low density and expand noticeably, making it easy to form a thick wall of grounds and a deep pit, while light-roasted beans are the opposite. In addition, pouring in small circles preserves the wall of grounds around the edge, and a large dose of grounds also provides enough support for the deep pit. But an attractive coffee bed does not equal good-tasting coffee; the real point of observing the coffee bed is to check whether the pouring was even and whether the wall of grounds was damaged. This article will systematically sort out the brewing logic behind the coffee bed for coffee lovers, helping everyone return to the brewing parameters themselves. [more…]

For a long time in the past, Shanghai was regarded as the city with the highest coffee density in China. However, the nearly three-month suspension of dine-in services dealt a heavy blow to Shanghai's catering industry, and coffee brands began to turn their attention to Chengdu. Data shows that Chengdu now has more than 7,000 coffee shops, ranking second nationwide, with independent coffee shops accounting for as much as 81.07%, far exceeding Shanghai's 57.01%. Luxury brands have also chosen to open coffee shops in Chengdu one after another, including LV, Cartier, Ralph's Bar, and Maison Margiela Café. Wangping Street, Mengzhuiwan, and Tangpa Street in Chengdu have become popular coffee districts, where teahouse culture and coffee consumption blend together. This article will analyze the data and trends behind this round of changes in the coffee city landscape. [more…]

Have you ever noticed how many coffee shops have opened near your office? One netizen shared a map showing that within a one-kilometer radius of their office building, there were as many as ten Manner locations, striking a chord with a large number of office workers. In the comments, some said there were twelve Manner shops nearby and thirty-three Starbucks, while others carefully counted the clusters of Luckin, Nowwa, and major tea beverage brands downstairs. Why do coffee and milk tea brands favor office buildings? Behind this are multiple considerations, including white-collar workers' high-frequency demand for caffeine, brands' pursuit of revenue stability, and the leasing needs of office buildings. What's more interesting is that the number of coffee shops has been regarded by netizens as an alternative indicator of the concentration of "workplace vibes." This article uses this phenomenon as a starting point to break down the underlying logic of workplace coffee consumption, with relevant observations from Front Street Coffee attached. [more…]

China's coffee consumption market continues to expand, with an average annual growth rate exceeding 15%, and coffee fairs and cultural festivals are emerging in endless succession across the country. Jiangmen, Guangdong recently held a Coffee Culture Week, attracting more than 150 coffee brands to exhibit, but what is even more noteworthy is the astonishing growth of coffee shops in this city—by the end of last year, the number had surpassed 1,500, with more than 400 new ones added during the year, an increase of over 35%. In the "2022 Top 100 Ranking of Chinese Cities by Number of Coffee Shops," Jiangmen ranked 21st nationwide, with 3.8 cafes per 10,000 people, a density that has already surpassed first-tier cities such as Shanghai, Shenzhen, and Guangzhou. Behind this phenomenon lies not only the profound accumulation of coffee culture in this century-old hometown of overseas Chinese, but also the combined impetus of returning young entrepreneurs starting businesses and chain brands pursuing a downward-market expansion strategy. This article will analyze the multiple factors behind the rapid rise of Jiangmen's coffee market and explore the future trajectory of involution in the industry. [more…]

Customer: "Boss, I'll have a Dirty!" Front Street: "Coming right up!" Customer: "Make it hot!" Front Street: "..., sorry, we don't have that. Dirty isn't made hot..."

As is well known, the unique appeal of a Dirty comes from the layering of milk and coffee. Whether it's the visual effect of the espresso gradually "dirtying" the milk, or the sensory experience of contrasting hot and cold, sweet and bitter—like ice and fire—it all stems from the fact that the two never fully blend. So if we want to make [more…]

As Yirgacheffe brings bright acidity reminiscent of lemon and citrus into the specialty coffee shops of more and more small county towns, many people begin to wonder: why do coffee beans need a light roast? And why did light-roasted coffee come about in the first place? In fact, coffee beans are not light-roasted in order to express citrus notes; rather, under light-roast conditions they more easily reveal citrus-like qualities. The roast level determines the basic direction of the flavor, unfolding in turn from acidity and aroma to body and bitterness. This article starts from the roasting practice at Front Street Coffee, combining first crack and second crack, bean density and origin characteristics to explain the flavor logic between light roasting and Yirgacheffe, and how roasters weigh the trade-off between a uniform appearance and acidity expression.

Many friends who are just getting into pour-over coffee share a common misconception: they believe that the deeper and more even the coffee bed is, the better the coffee tastes. In reality, the shape of the coffee bed only reflects the pouring method and has no direct connection to coffee flavor. This article starts from a customer inquiry at Front Street's shop to explain why the coffee bed in specialty coffee is sometimes flat, and which factors truly determine coffee taste. It also shares three practical points: appropriately increasing the water flow, concentrating the hot water in the center, and choosing coffee beans that are not too high in density, helping you easily produce a symmetrical, deep coffee bed at home. The article also uses Front Street Yirgacheffe Gudingding, PWN Golden Mandheling, and others as examples to illustrate the differences in how various beans perform. [more…]

More and more high-performance small coffee machines are making their way into homes, but if you want to consistently pull a good espresso at home, a great machine alone is far from enough. Front Street Coffee has put together the most common pitfalls in home scenarios: some people, for convenience, directly buy ready-made coffee grounds, overlooking the three major hidden risks of flavor dissipation, loss of oils, and inconsistent grind size; some people repeatedly level the grounds when tamping, which instead causes uneven density in the puck and channeling during extraction; and still others, after locking in the portafilter, delay pressing the extraction button, letting the puck bake on the hot brew head and develop a burnt, bitter taste. The article breaks down the causes of these problems one by one and offers actionable suggestions for improvement, helping beginners avoid unnecessary detours. [more…]

Dirty has always been a popular product in coffee shops thanks to its high aesthetic appeal and the unique experience of hot and cold colliding. When making a Dirty, using a chilled glass can extend the layering effect between the espresso and the milk, but should you use a refrigerated glass or a frozen glass? Through comparative experiments, Front Street Coffee found that although a frozen glass can widen the initial temperature difference, it also accelerates the dissipation of the layers, and the milk's mouthfeel and aroma are slightly compromised. The rise in popularity of -86°C Dirty has brought frozen glasses into the spotlight once again. This article explains in detail the differences between refrigerated and frozen chilled glasses, the points to note when making a Dirty with a frozen glass, and why purified milk is the best partner for a frozen glass, helping you fully understand the intricacies behind this dirty coffee.

Coffee enthusiasts often ask in the shop exactly what the difference is between Ethiopia's G1 and G2, what Kenya AA actually means, and what Costa Rica's SHB grade signifies. These combinations of letters and numbers actually reflect how each producing country evaluates the quality of green coffee beans.
