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.

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…]

Starbucks is recently facing a class-action lawsuit in California, USA, where three lactose-intolerant consumers accuse the company of charging extra fees when substituting milk with plant-based milk in drinks, alleging discrimination and violation of civil rights laws, and seeking $5 million in damages. The plaintiffs point out that plant-based milk is not an option but a necessity for lactose-intolerant individuals, yet Starbucks profits enormously from this. Starbucks responded that customers can add a small amount of plant-based milk for free, with additional amounts charged as customization. Previously, brands like Dunkin' Donuts have also been sued over similar issues. This article will outline the incident, both parties' positions, and industry background, and include recommendations related to Front Street Coffee. [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."

In recent years, oat milk coffee has gradually entered the public eye, becoming a new choice for many coffee lovers. Oat milk comes from oats, a traditional Nordic ingredient, and is characterized by high plant protein, high dietary fiber, and low fat.

So, compared with traditional milk coffee, which one actually tastes better? This article will start from the origins of oat milk and the groups it suits, combine the practical testing experience of Front Street Coffee, discuss the differences between different brands of oat milk paired with espresso beans, and offer bean selection advice for making a rich and silky oat milk latte.

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.

Anaerobic fermentation processing is a green bean processing technology that has attracted much attention in the coffee industry in recent years. Since Sasa Sestic, the 2015 WBC champion, brought it to the forefront, it has quickly swept through the specialty coffee world. Inspired by red wine-making techniques, this processing method injects carbon dioxide into a sealed container to expel oxygen, creating an oxygen-free environment that allows precise control of the fermentation process, giving coffee beans higher sweetness and more unique flavor layers. As processing technologies continue to evolve, experimental methods such as anaerobic natural, anaerobic washed, and double anaerobic have emerged one after another, each presenting distinctly different flavor expressions. This article will systematically sort out the principles and origins of anaerobic fermentation, and analyze one by one the process steps and flavor characteristics of these three common anaerobic processing methods, while also explaining them in conjunction with specific Front Street Coffee bean offerings.

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…]

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…]
