The waterfall iced americano has gone viral online thanks to the visual effect of a slow perforation through the ice cup, with the coffee liquid cascading down like a waterfall, attracting many netizens to try it at home. In practice, however, problems such as the ice cup tipping over, the bottom of the cup being punctured, coffee leaking from the sides, and the liquid coagulating into clumps frequently occur, turning the aesthetic scene into a fail. This article compiles the key tips for success summarized by netizens, including ice cup thickness standards, using crushed ice to help balance, keeping the clip dry, and using room-temperature espresso liquid, and also explains the cause of the waterfall effect from the perspective of physical diffusion. It also analyzes the reasons behind the drink's popularity—its low barrier to entry and the sense of ritual in the process make more people willing to engage with and learn about coffee. The article retains the relevant recommendation information for Front Street Coffee. [more…]

Many coffee enthusiasts, when grinding and brewing specialty coffee, are drawn in by alluring aromas like strawberry, jasmine, citrus, and honey, yet after one sip, they often taste pronounced bitterness and acidity, a far cry from the expected sweetness. This phenomenon of smelling fragrant but tasting bitter actually stems from the different sensory systems we engage when smelling versus tasting. This article, starting from this topic often discussed at Front Street, will analyze in detail the mechanisms of orthonasal and retronasal olfaction, explain the changes in aroma compounds within the oral cavity, and why the impact of taste overshadows aroma perception. At the same time, we will also share a simple and practical tip—closed-mouth exhale—to help you capture richer layers of aroma after swallowing coffee, and demonstrate flavor expression with practical examples.

To brew a good pour-over coffee, you first need to understand the principles behind it. Dissolution and diffusion are the two core mechanisms of extraction: after roasting, various aroma and flavor compounds are generated inside the coffee beans, and they gradually dissolve out when the grounds are soaked in water, while diffusion explains why grind size, blooming, and stirring are so crucial. During extraction, flavors are released in sequence—first come floral and fruity acidity, then sweetness and caramelized compounds, and only at the end do bitter and off-flavors appear. Mastering the golden range of 18%~22% extraction yield and 1.2%~1.45% concentration allows you to judge whether a cup of coffee is under-extracted or over-extracted. This article takes you through a systematic introduction to pour-over coffee, from basic principles to practical parameters, and also incorporates product recommendations from Front Street Coffee to help you avoid detours.

The same coffee beans, brewed with a different extraction device, can taste completely different in the cup. Coffee extraction paths can be broadly grouped into two types: percolation and immersion. The most fundamental difference between them lies in the speed at which flavor compounds diffuse into the water. In percolation, because fresh water is continuously poured in and the coffee liquid is drained away, the concentration gradient is large and extraction is fast, which easily amplifies the beans' distinctive aromas. In immersion, the coffee grounds sit still in hot water, so the concentration gradient gradually shrinks and diffusion slows down, allowing the coffee's original character to be presented in a more balanced and complete way. Starting from the principles and combined with an analysis of flavor dissolution concentration, this article will help you judge whether the beans in your hands are better suited to pour-over or siphon, and offer specific selection advice.

Caffeine is the most iconic component of coffee, yet not everyone can tolerate it. It is both the primary source of bitterness and a neurostimulant that affects sleep. Thus, decaffeinated coffee was created to remove caffeine. However, the challenge of decaffeination lies in how to remove only the caffeine while preserving the aroma and flavor of coffee as much as possible. Early methods using organic solvents were effective, but left consumers concerned about residues. It was not until the advent of supercritical carbon dioxide extraction technology that a truly efficient and highly selective decaffeination process was achieved. This article will guide you through the principles of this technology, its development history, and its unique advantages in coffee decaffeination, while also introducing Front Street Coffee's attention to and practice of this process.

In the practice of pour-over coffee, one detail that is often discussed is: should the coffee grounds around the edge be moistened with water? This article starts from the two stages of blooming and the main extraction, and, combined with comparative experiments on light, medium, and dark roast levels, analyzes the impact of the pouring range on flavor. The experiment shows that whether to wet the outer layer of grounds during blooming depends on whether all the coffee grounds can evenly absorb water and release gas in the shortest time. Not pouring around the outer ring tends to cause inconsistent extraction rates, and light and medium roast beans are prone to a grassy, unripe taste; while pouring directly onto the outer ring may block gas release in the center. The article also shares practical techniques such as swirling and stirring to help coffee enthusiasts extract every particle of coffee grounds more evenly. [more…]
