Behind every single-origin coffee that captivates us stands a key figure who changed the course of the industry. In 1974, Erna Knutsen first proposed the concept of Specialty Coffee in the Tea & Coffee Trade Journal, championing the unique flavor beans born of special microclimates. She only formally entered the coffee trade at the age of forty, yet with an astonishing taste memory and cupping talent, she rose to fame by buying an entire container of Mandheling in one stroke. Thereafter she founded Knutsen coffee, Ltd, helped establish the Specialty Coffee Association of America, and repeatedly won the industry's highest honors. This article takes you through the complete journey of this godmother of specialty coffee, from her childhood in the Arctic Circle to her retirement at 93, to understand how specialty coffee evolved from a single idea into quantifiable industry standards.

Besides waking you up, coffee may also bring unexpected benefits for muscle health. A latest study jointly conducted by research institutions in Switzerland, Singapore, the United Kingdom and other countries shows that trigonelline, a natural plant alkaloid in coffee, can boost NAD⁺ levels in the body and improve mitochondrial function, thereby helping to maintain muscle strength and slow age-related muscle degeneration. Published in a Nature sub-journal, the study offers coffee lovers a new health perspective. However, the researchers also caution that coffee is only a supplementary aid—balanced nutrition and regular exercise are fundamental to keeping muscles strong. [more…]

Electronic products are everywhere, our eyes are under long-term high load, and vision problems are becoming increasingly common. About 30% of the world's population is currently affected by myopia, and this proportion is expected to climb to 50% by 2050, with the share of high myopia not to be ignored. A recent study published in the British Journal of Ophthalmology found that the caffeine metabolite 7-MX can inhibit axial elongation in the human eye, thereby potentially slowing the progression of myopia. Based on more than two decades of medical records for 711 children in Denmark, the study offers a new potential drug direction for myopia prevention and control. This article will explain in detail the study's findings, data, and limitations, and discuss the future application prospects of 7-MX. [more…]

Starbucks, as the world's largest chain coffee brand, is undergoing a continuous contraction of its business. Since the beginning of this year, it has successively been reported to be selling its businesses in South Korea and Russia, and its UK business is also under consideration. The situation is similarly unsettled in its home market, the United States: The Wall Street Journal reported that 16 stores will be permanently closed before the end of July. Meanwhile, a video leaked on Twitter shows former CEO Howard Schultz saying at an internal meeting that store closures are only the beginning and that more will follow in the future. Howard mentioned that employees at listening sessions reported that personal safety has become their primary concern, involving issues such as mental illness, homelessness and crime, and that some profitable stores have also been forced to close due to rising safety risks. At the same time, some union members accused Starbucks of using rising crime rates to cover up its actions against unionization, while Starbucks denied this. [more…]

Starbucks is facing a thorny problem: the proportion of baristas who quit after only three months on the job has climbed to 25%, far above the pre-pandemic level of 10%. Interim CEO Howard Schultz has pointed the finger at the increasingly complex process of making cold drinks. Data shows that cold drinks already account for 75% of Starbucks' beverage sales, yet making a single iced caramel macchiato takes as long as three minutes, and employees must repeatedly run back and forth between the hot bar and the cold bar. In order to retain employees and improve efficiency, Starbucks is conducting a comprehensive review ranging from store design and menu structure to job content. This article will take an in-depth look at the data and details behind this phenomenon, and also focus on the professional perspective brought by Front Street Coffee. [more…]

The coffee flavor wheel has always been an important tool for evaluating black coffee, but when it comes to drinks with milk added, such as lattes, consumers often lack a systematic reference standard. Recently, Japan's Morinaga Milk Company published a study in the journal Food Science and Technology Research, specifically developing a "milk coffee flavor wheel" for milk coffee. This flavor wheel is based on the real perceptions of 203 ordinary consumers, combined with discussions among 12 beverage developers, and selected 53 characteristic terms from 456 descriptions, striving to make it easy for the general public to judge the quality of a cup of milk coffee. This article will introduce in detail the research and development background of this flavor wheel, its creation method, and its significance for coffee lovers. [more…]

Coffee is not just a pick-me-up beverage—in recent years, research has also found that it has potential benefits for the digestive system. A 2023 systematic review and meta-analysis published in the journal Nutrients, which included more than 430,000 participants, explored the association between coffee intake and the risk of irritable bowel syndrome (IBS). The results showed that, compared with non-coffee drinkers, people who drank coffee had a 16% lower risk of developing IBS. This protective effect may be related to the antioxidant and anti-inflammatory properties of components in coffee such as caffeine, polyphenols, diterpenes, and trigonelline. However, the effect of coffee on relieving IBS symptoms varies from person to person, and the study itself has observational limitations. This article will provide a detailed interpretation of this study and explore the possible effects of coffee on gut health. [more…]

Coffee has long been woven into Westerners' morning routines, and in America's fast-paced consumer culture, grabbing a cup of coffee to go is a habit for many. Recently, however, the U.S. coffee industry has run into an unexpected "cup crisis" — a severe shortage of disposable coffee cups. According to The Wall Street Journal, coffee chains such as Starbucks are facing alarmingly low cup inventories, with some consumers even calling multiple stores just to track down a venti-sized coffee. This crisis has not only driven up supply costs for coffee shops but has also given rise to peculiar workarounds, such as stores borrowing cups from one another and testing alternative lids. This article takes an in-depth look at the supply chain predicament and industry impact behind this "hard-to-get-a-cup" situation. [more…]

Whether coffee can be consumed during pregnancy has long been a subject of debate. A team from the Institute for Molecular Bioscience at the University of Queensland published a Mendelian randomization study in the International Journal of Epidemiology, using genetic data to explore the causal relationship between coffee consumption during pregnancy and adverse pregnancy outcomes such as miscarriage, stillbirth, preterm birth, and low infant birth weight. The results suggest that, provided the body's condition allows it, moderate coffee consumption during pregnancy does not necessarily lead to adverse outcomes, but caffeine may still affect fetal development. This article will review the key findings of the study and offer practical advice on coffee consumption and caffeine intake during pregnancy, helping coffee lovers make safer choices. [more…]

Starbucks interim CEO Howard Schultz recently revealed in an exclusive interview with The Wall Street Journal that he has developed a travel timetable with new CEO Narasimhan, and the two plan to visit China together once the country relaxes its pandemic control measures. Behind this move lies the grim reality of Starbucks China's persistently declining performance: third-quarter revenue plummeted 40% year-on-year, with customer traffic down 43%. Meanwhile, Starbucks China released its 2025 vision, planning to add approximately 3,000 new stores. Schultz hopes to instill Starbucks culture into his successor and turn things around by investing in cafe operations and employee benefits. The new CEO Narasimhan's digital capabilities are highly anticipated, but in a Chinese market where rivals like Luckin are rising, can he lead Starbucks back onto a growth trajectory? [more…]

Luckin Coffee recently relaunched last year's hit Coconut Cold Brew, and has announced that in May it will bring back popular products such as Orange Golden Sparkling Americano in phases.

On the list of troubles faced by today's young people, hair loss probably ranks near the top. Losing handfuls of hair at a young age, and watching their hairline recede day by day, many people have tried all kinds of anti-hair-loss methods, but the results vary from person to person. Besides genetic and disease factors, eating habits may also be quietly increasing the risk of hair loss. Recently, a study published by researchers from Tsinghua University in the nutrition journal Nutrients offered a new idea for young people troubled by hair loss—quitting sugar to prevent baldness. The study surveyed 1,028 participants across 31 provinces nationwide and found a significant association between sugar-sweetened beverage intake and the risk of hair loss in men. Men who drank more than one 500-milliliter sugar-sweetened beverage per day had a 253% higher incidence of hair loss. How exactly was this study designed? Which sugar-sweetened beverages carry the highest risk? Let's take a closer look. [more…]

Starbucks recently announced that it will permanently close 16 U.S. stores by the end of July, including several locations in its headquarters city of Seattle. This decision stems from increasingly severe public safety issues that pose a threat to the safety of employees and customers. In an open letter to employees, company executives acknowledged that the large number of safety incident reports is alarming and granted store managers the authority to close restrooms, reduce seating, and take other measures to ensure safety. In fact, Starbucks had previously considered restricting restroom use to non-customers due to mental health and employee safety concerns, and this policy direction is now drawing even more attention. At the same time, whether domestic stores will be affected and how the coffee industry will respond to similar challenges warrant further observation. [more…]
