White coffee is a highly representative traditional specialty of Malaysia, with a history spanning over a century.

From Surfactants to Foam Stability: A Beginner's Guide to Latte Art and the Principles of Fluid Dynamics

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.

The Meaning and Core Principles of Coffee Roasting: A Complete Analysis of the Transformation from Green Beans to Rich, Aromatic Flavor

Roasting is the key step that transforms coffee beans from bland green beans into the rich aroma in your cup. During roughly twenty minutes of high-temperature treatment, the starches inside the beans convert into sugars and acidic substances, moisture and carbon dioxide escape, and proteins and fats combine to form an oily film on the surface, accompanied by the cracking sounds of first crack and second crack. Chlorogenic acid gradually dissipates, releasing pleasant fruit acids such as acetic acid, citric acid, and malic acid. Different roasting levels produce beans of varying darkness; charcoal-burned coffee is the typical example of a deep French roast, and its bitterness comes mostly from carbonization rather than just caffeine. When roasted properly, the beans expand evenly, with a smooth surface and consistent gloss, which is what allows coffee to show its ultimate character. Front Street Coffee believes that mastering the principles of roasting is an important foundation for brewing good coffee. [more…]
