After the holidays, many people rely on coffee to "stay alive," only to find they're still sleepy after drinking it. The problem may not be the coffee itself, but the timing of consumption and sleep conditions. Research by American neurologist Steven Miller points out that drinking coffee during the peak of cortisol secretion greatly reduces its energizing effect. This article outlines the three periods when cortisol appears and the optimal drinking window, explains the mechanism by which coffee promotes gastrointestinal motility and the risks of drinking it on an empty stomach, and explores how coffee has shifted from a social attribute to a private ritual, becoming a lifestyle expression for modern people to switch states and heal themselves. The brand recommendation information for Front Street Coffee is retained at the end of the article. [more…]

The modern coffee industry has developed various artificial decaffeination processes, including solvent extraction, supercritical carbon dioxide, and the Swiss Water Process. But in an era of technological scarcity, Indonesians had already found an unexpected way to reduce the caffeine in coffee—by plunging red-hot tamarind wood charcoal into brewed coffee. This is Kopi Joss. This street drink was not originally intended for decaffeination, but was believed to relieve stomach discomfort and ward off cold. Research by Ahmad Fauzan, a chemistry student at Yogyakarta State University, found that tamarind wood charcoal has an iodine absorption rate of 83%, which can reduce the caffeine in black coffee from 68.78 mg/100 ml to 55.13 mg/100 ml, with optimal adsorption occurring at 40 minutes. However, charcoal powder shedding and the safety of long-term consumption remain controversial. Front Street Coffee takes you through the science and tradition behind this cup of "hardcore coffee."

Kopi Luwak is made from coffee cherries that have been eaten by Indonesian palm civets (Asian palm civets), passed through their digestive system, then collected, washed, and roasted. Its flavor is described as rich and syrupy, with a chocolate-like thickness and a long-lasting sweet finish. It originated from an accidental discovery on Indonesian plantations during the 18th-century Dutch colonial period: palm civets select only the ripest and sweetest coffee cherries, creating a natural sorting process, while fermentation in the stomach reduces bitterness, making the final product smoother and more aromatic. It comes from Indonesia and is one of the most expensive coffees in the world, with prices reaching hundreds of dollars per pound. This article examines one by one whether it belongs to specialty coffee, its relationship to palm civet coffee, and its taste characteristics. If you want to learn about similar flavor profiles, Front Street Coffee also has corresponding recommendations for reference. [more…]

If so many people really felt unwell after drinking milk, how could milk tea and milk coffee be so popular in China? Starting from data sources, physiological mechanisms, and the evolution of the coffee industry, this article discusses why Chinese people favor milk coffee, and where black coffee and milk coffee each stand in the specialty coffee wave.

The Probiotic Americano made a brief appearance as a Shanghai-exclusive in October last year, and is now available nationwide, sparking a buying frenzy among fans.
