Recently, discussions about decaf coffee have been steadily heating up on social media, with chain brands such as Tims, Starbucks, and Blue Bottle launching decaf product lines, drawing widespread attention. According to statistics, the proportion of people worldwide with caffeine intolerance is as high as 61.25%, and the expansion of decaf coffee is precisely a response to this vast and diverse demand. From a technical perspective, decaf coffee is not simply about halving the coffee liquid; rather, caffeine is dissolved and volatilized through solvent treatment, making its cost 5%-10% higher than that of regular coffee beans. Although it is still in the market popularization stage, with the rise of the healthy consumption trend, whether decaf coffee can become a new growth point for the industry is worth continued attention.

Guming obtained approval for a Hong Kong listing filing, becoming the first company to receive the green light amid the new tea beverage IPO wave. Meanwhile, its winter new product "Dark Chocolate Mocha" has drawn attention for its rich cocoa flavor, but has also been jokingly called a "great gut cleanser" due to a large number of consumers reporting diarrhea after drinking it. The official recipe includes cocoa liquor, cocoa powder, old salt syrup, light-feel thick milk, milk, and freshly ground coffee. The triple cocoa brings a rich and smooth taste, but many people find it sweet and cloying, like chocolate milk. The cause of the diarrhea may point to lactose intolerance or caffeine sensitivity, and iced drinks are more likely to aggravate the reaction. This article will sort out the timeline of the incident and consumer feedback, and recommend related products from Front Street Coffee. [more…]

Front Street Coffee will also, drawing on its own products, discuss the real reasons why decaf coffee tastes inferior, and why choosing green beans of good quality is more crucial than the decaffeination technology itself.

Regarding caffeine in tea, many plausible-sounding claims circulate: some believe black tea has far more caffeine than green tea, some think green tea contains almost no caffeine, and others are convinced that the deeper the fermentation, the more caffeine. Is any of this actually true? All tea leaves from the tea plant—unless decaffeinated—inherently contain caffeine, and the level depends more on plucking tenderness, tea cultivar, cultivation methods, and climate conditions than on the degree of fermentation or oxidation. Buds and newly opened leaves have the highest caffeine concentrations, African Assamica tea plants are generally higher than Chinese varieties, and older leaves plucked in autumn tend to be lower. In addition, theanine, unique to tea, works synergistically with caffeine to deliver a calm yet alert lift—quite different from the jolt of coffee. This article breaks down these factors one by one and explains why Front Street Coffee labels the caffeine content of the teas it sells, helping you make a more suitable choice based on your own tolerance.

For consumers who are sensitive to caffeine but unwilling to give up the flavor of coffee, decaf options have always been an important selling point for chain brands, and Starbucks, with its rich product line and convenient decaf checkbox feature, has become the top choice for this group. However, recently many customers have noticed that many Starbucks stores in China have quietly removed the decaf espresso option from new products, and those who want decaf coffee can only choose from a fixed selection of classic products. This change has caused confusion and dissatisfaction among the decaf-demand group. What exactly caused the stores to make this adjustment? According to informed partners, this is directly related to the Golden Roast beans launched two months ago and the bean hopper configuration of the stores' coffee machines. This article will sort out the course of the incident, consumer feedback, and the equipment limitations behind it, and explain which stores can still normally provide decaf new products. [more…]

For today's young people, coffee has long been woven into the rhythm of daily life—whether for a caffeine boost, socializing, or fitness, everyone has their own reasons. Yet for some, the purpose of their daily cup is rather unusual: relieving constipation. From Luckin's new drink being jokingly dubbed a "diarrhea-inducing whiz" by netizens, to similar feedback frequently received for drinks from brands like Starbucks, Mstand, %Arabica, and Manner, the relationship between coffee and bowel movements has sparked widespread discussion. Is this a food safety issue, or is it down to individual differences such as lactose intolerance or the stimulating effect of iced drinks? This article will analyze the phenomenon from multiple angles to help coffee lovers view their daily cup more rationally. [more…]

A lactose intolerance data chart produced by a foreign website has led many people to mistakenly believe that 90% of Chinese people cannot drink milk. But medically, lactose intolerance and lactose malabsorption are actually two different concepts. The former refers to symptoms such as abdominal pain, bloating, and diarrhea, while the latter merely indicates that the small intestine's efficiency in absorbing lactose is somewhat low, and does not necessarily cause discomfort. 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. [more…]

After Luckin Coffee launched its Prune Latte, social media platforms saw a surge of discussions about gastrointestinal reactions after drinking it, even jokingly dubbed the "suppository of the coffee world."

This article will review the course of events, the official explanation, and netizen feedback, and analyze why the same beverage triggers such consistent physiological reactions. At the same time, the professional communication channel of Front Street Coffee is retained at the end of the article for coffee enthusiasts to discuss further. [more…]

For coffee lovers who are lactose intolerant or allergic to dairy, plant-based alternatives such as oat milk and almond milk allow them to enjoy lattes without worry. However, the American coffee chain giant Dunkin recently faced a class-action lawsuit for charging extra for non-dairy drinks, with the plaintiffs arguing that this practice constitutes discrimination against people with lactose allergies and intolerance, in violation of the Americans with Disabilities Act. This is not the first time the U.S. coffee industry has faced legal disputes over plant-based milk pricing; Starbucks has also previously faced similar allegations. This article will review the course of events, the legal basis, and industry reactions, and explore the cost and fairness issues behind the controversy over non-dairy drink pricing. [more…]

A daily cup of coffee has become the standard for many office workers, and some even have more than one a day. But can drinking too much coffee place a burden on the body? Recently, a netizen shared an experience of being banned from coffee after visiting a traditional Chinese medicine doctor, who even said, "If you keep drinking, you'll die."

Luckin Coffee's recently launched Fair Isle Latte has quickly become a new favorite among some office workers and tea-coffee enthusiasts, thanks to its flavor reminiscent of Assam milk tea and its powerful energizing effect. However, a large number of "warning" posts have emerged on social media, with many consumers reporting that they couldn't sleep all night after drinking it, and even experiencing symptoms such as hand tremors, dizziness, and heart palpitations, with some seeking medical attention late at night.

This starkly contrasting feedback has plunged this new drink, which blends espresso with Ceylon black tea, into controversy. This article will sort through the various viewpoints, explore the effects of differences in caffeine tolerance, and offer professional advice from Front Street Coffee. [more…]

CHAGEE recently launched its winter new product "Qingshan Qigu" across its nationwide stores, featuring Wanxi yellow large-leaf tea paired with brown rice buckwheat and milk. The official description highlights its rich aroma of scorched rice and roasted rice. However, after this new product hit the market, consumer feedback has been sharply polarized—aside from disputes over the flavor, a large number of netizens have complained on social media about being unable to sleep all night after drinking it, with the number of insomnia posts even far exceeding taste reviews.

Is it the caffeine at work or individual differences? This article takes you to find out. [more…]

This Monday, Luckin Coffee teamed up with Taiwanese illustrator Jimmy Liao to launch a co-branded offering titled "Poems for the Moon," alongside the simultaneous release of a new Oolong Latte. This new addition to their tea-coffee series, which uses Wuyi Mountain Da Hong Pao as its tea base and offers an optional oat milk version, quickly sparked discussions among netizens after its launch. Apart from its taste being compared to Assam milk tea, what drew even more attention was its post-consumption "smooth" effect—a large number of consumers on social media reported feeling the urge to use the restroom shortly after drinking it, with some making multiple trips in a single day, jokingly dubbing it the "new toilet-busting divine water." Some speculate this is related to the thick milk component in the drink and lactose intolerance. Although the effect varies from person to person, this unintended function has actually tempted many netizens who were previously uninterested to give it a try. [more…]

Oat milk, as a dairy-free plant-based milk, has attracted much attention in coffee circles and the field of healthy eating in recent years, and chain brands such as Starbucks have also adopted Oatly oat milk as a milk alternative. It is especially suitable for vegans, people with lactose intolerance, and consumers allergic to milk. During production, oat milk is made by soaking oats, filtering the slurry, and often adding extra nutrients such as calcium and vitamin B12, making its nutritional value richer. Front Street Coffee will guide you through understanding the specific health benefits of oat milk and compare its nutritional differences with whole milk and low-fat milk, helping you choose the dairy drink that suits you in a more scientific way.

Starbucks recently announced that starting November 7, stores in the United States and Canada will no longer charge extra for dairy alternatives. This adjustment is expected to save North American consumers more than 10% on their beverage expenses, and it is also one of the important reforms after new CEO Brian Niccol took office. Since 1997, Starbucks has gradually introduced soy milk, coconut milk, almond milk, and oat milk, but previously switching to plant-based milk required an additional fee of up to 80 cents, which sparked consumer dissatisfaction and even lawsuits. Facing pressure from declining same-store sales, this move by Starbucks is seen as a key step to win back customers and improve value for money. Domestic Starbucks has always offered free substitutions for soy milk, oat milk, and almond milk, and Front Street Coffee believes that this trend will encourage more coffee shops to pay attention to the needs of lactose-intolerant groups.
