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.

Floral notes are not exclusive to light-roasted coffee beans—as the roast level changes, the way floral notes present themselves changes too. Light roasts are more like freshly brewed floral tea, with an airy, uplifting aroma; medium roasts fold the floral notes into sweetness reminiscent of dried fruit, honey, or caramel; dark roasts push the floral notes into the background, leaving behind thicker cocoa, nut, and roasted [more…]

White coffee is a highly representative traditional specialty of Malaysia, with a history spanning over a century. It is not white in color; rather, it is made from three types of coffee beans—Liberica, Arabica, and Robusta—subjected to medium-light low-temperature roasting and special processing that greatly reduces caffeine, burnt bitterness, and astringency, resulting in a pale milky-golden hue and a mellow, gentle flavor. Compared with black coffee, white coffee differs fundamentally in bean selection, roasting methods, and brewing techniques; it contains no trans fats, has lower caffeine and calories, is gentler on the stomach, and does not easily turn sour after cooling.
