Molly Tea recently launched a pomelo-coconut series, including three new drinks: Pomelo Apple Coconut, Pomelo Jasmine Coconut, and Pomelo White Orchid Coconut. With a combination of refreshing pomelo-mint milk foam and fruit coconut water, they quickly attracted a large number of consumers. However, the most popular Pomelo Apple Coconut showed an abnormal phenomenon after adding the milk foam: the pink color faded, white flocculent substances appeared, and the liquid became cloudy like soy milk, raising customers' doubts about beverage safety and store ingredients. Store employees explained that this was caused by a chemical reaction between the protein in the milk foam and the vitamin C in the apple juice and pomelo juice, and was not due to spoiled ingredients. This article will reconstruct the course of the incident, consumer feedback, and the official response, and include the professional perspective of Front Street Coffee to help you understand the scientific principles behind this color-changing drink.

To create beautiful and long-lasting latte art patterns, the choice and handling of milk actually matter a great deal. Whole milk, because of its higher fat and protein content, makes the milk foam more stable and fine; keeping the steaming temperature below 70°C avoids the negative effects of lactose caramelization and protein denaturation; refrigerated storage extends the frothing time, making the foam denser and creamier. Drawing on years of experience, Front Street Coffee recommends using freshly roasted medium-dark roast espresso blend beans as the base, and shares two products suitable for beginners: the Front Street Dark Cocoa Blend and the Front Street Strawberry Candy Espresso. This article will explore these three dimensions, explaining why latte art has these requirements for milk, to help you create your ideal patterns at home. [more…]

In the cold of winter, a hot latte or flat white is many people's beloved choice. Many customers ask for "the milk to be steamed hotter," but baristas often insist on the widely accepted steaming range of 55°C–65°C. Why does milk coffee, once the temperature rises, instead become scalding, less sweet, and coarse in mouthfeel? The core reason lies in protein denaturation and changes in lactose sweetness. Starting from the principles of milk foam formation, this article explains why milk above 70°C leads to difficulty in latte art, separation of foam and coffee, and accelerated foam collapse, and points out that 68°C is already the peak temperature. It also shares the experimental conclusion of Front Street Coffee: 60°C–70°C is the range where lactose sweetness is most pronounced. Finally, it offers practical suggestions, such as using preheated ceramic cups to slow cooling, so that milk coffee maintains its best flavor at a suitable temperature. [more…]

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.
