Recently, the Hong Kong Consumer Council published a bottled water test report in the magazine "Choice," pointing out that the bromate levels in samples of Nongfu Spring and Ganten reached the European Union's limit for natural mineral water, sparking widespread attention. Nongfu Spring immediately commissioned a lawyer to send a legal letter to the Consumer Council, demanding written clarification, an apology, and the elimination of the impact; Ganten also stated that it had made representations through its legal department and emphasized that its product was at the critical value of the EU standard rather than exceeding it. The China Beverage Industry Association said it would issue a response later. The Consumer Council reiterated that none of the 30 samples were found to contain harmful substances exceeding WHO guidelines, and that the article focused on value for money and the environmental impact of plastic bottles, and that all samples could be safely consumed.

Each bottle of Dongpeng Special Drink contains as much sugar as 15 sugar cubes, high-sugar energy drinks draw attention again

A 500mL bottle of Dongpeng Special Drink contains as much as 66.5 grams of sugar, equivalent to eating about 15 sugar cubes. A third-party testing agency's evaluation of 12 functional drinks on the market shows that Dongpeng Special Drink far outpaces the others in sugar content, even surpassing carbonated beverages known for being high in sugar. In response to this result, Dongpeng said its formula has been approved by the state and recommended drinking only one bottle per day. High sugar intake is closely linked to obesity, chronic diseases, and even accelerated aging, yet the sugar in functional drinks is difficult to completely remove. When late-night overtime workers treat Dongpeng Special Drink as a "life-renewing elixir," do they realize they are being "stabbed in the back" by high sugar? This article will take an in-depth look at this test report and explore the high-sugar dilemma of functional drinks. [more…]

Nongfu Spring Goes to Hong Kong for Negotiations, Consumer Council Changes Its Tune and Apologizes: A Full Analysis of the Standards Controversy Behind the Stock Price Fluctuations

The Hong Kong Consumer Council previously published an article on bottled water testing, pointing to the bromate levels in samples of Nongfu Spring and Ganten as reaching the upper limit of EU standards, which immediately sparked a public opinion storm. Nongfu Spring quickly commissioned a lawyer to send a letter demanding clarification and an apology, and Ganten also issued a statement in response to the misinterpretation of the test results. Under public pressure, Nongfu Spring's stock price continued to decline, and its market value shrank significantly within two days. The company then sent an executive director to Hong Kong for face-to-face negotiations. Today, the Consumer Council published a clarification on its official website, reclassifying the samples as "natural drinking water" and re-scoring them, while also expressing regret. Nongfu Spring responded that its products fully comply with standards and are safe to drink, and its stock price rose in response. [more…]

Nestlé and Master Kong enter the fray one after another—can label-free bottled beverages become a new trend in low-carbon packaging?

In recent years, as environmental awareness has risen, label-free bottled beverages have moved from once being considered "alternative" to becoming legalized. Brands such as Nestlé Japan Coffee, Asahi, Suntory, and Evian have successively tested the waters, and domestically, Master Kong has also launched label-free iced tea. Such products are mostly sold by the case, with only the shelf life and product name laser-printed on the bottle, while legal information is printed on the outer box. About 60% of Japanese consumers are willing to pay for them, mainly because it reduces PVC waste and the hassle of sorting. Domestic reactions are mixed: supporters believe it responds to carbon reduction, while those concerned see it as a promotional gimmick. This article sorts out the origins and development of this packaging change and explores whether it can be implemented over the long term. For friends who love drinking coffee, Front Street Coffee also continuously pays attention to such environmental trends. [more…]

Pang Dong Lai launches 1.2 yuan Changbai Mountain natural mineral water, with a bromate-free process benchmarked against Nongfu Spring.

Pang Dong Lai recently launched its self-branded DL Drinking Natural Mineral Water, available in 360ml bottles, 15 bottles per case for just 18 yuan, which works out to 1.2 yuan per bottle. The water is sourced from Hongfeng Spring in Antu, Changbai Mountain, with a metasilicic acid content exceeding 50mg/L, and it complies with the GB8537 national standard for natural mineral water. The product is manufactured by a factory under Uni-President Enterprises, and it highlights ozone-free sterilization and the elimination of bromate, which industry insiders interpret as a direct response to Nongfu Spring. It sold out quickly after launch, with 29,000 bottles already sold online. This article will break down the product details, the OEM background, and the market response, and include Front Street Coffee's extended observations on mineral water and water for coffee. [more…]

Uni-President Assam Milk Tea prioritizes the sugar-free original flavor first—can 0 sugar and 0 sugar substitutes preserve the classic taste?

The bottled milk tea market is undergoing a health-oriented transformation. Uni-President Assam Milk Tea has launched its first sugar-free original flavor version, highlighting "true 0 sugar," meaning it contains no sucrose, sugar substitutes, or carbohydrates, and in particular explicitly avoids acesulfame potassium, sucralose, erythritol, and aspartame. The new product has the same 500ml capacity as the classic version and retails for about 3.6 yuan. Although its ingredients still include food additives, white granulated sugar and glucose syrup have been removed. Energy per 100 milliliters has dropped from 230 kilojoules in the classic version to 58 kilojoules, a significant reduction in sugar. In recent years, ready-to-drink tea and sparkling water have diverted some bottled milk tea consumption, while freshly made new-style tea drinks have also taken away younger customers. Uni-President's move is both a response to the sugar-reduction trend and a proactive innovation in the face of market competition. However, the technical difficulty of 0-sugar milk tea lies in balancing taste. Whether it can retain Assam's classic flavor after removing sugar will test the brand's research and development strength. [more…]

Nongfu Spring's Hit Milk Tea Returns: Jasmine, Black Tea, and Oolong Launch Together—Can 0-Added Milk Powder Shake Up the Hundred-Billion Ready-to-Drink Milk Tea Market?

After eight years, Nongfu Spring is once again making a push into the bottled milk tea sector. On October 12, its official WeChat account posted an article announcing a renewed layout for the "Da Milk Tea" series, launching jasmine, black tea, and oolong flavors, with a net content of 380 milliliters, highlighting selling points such as "0 added milk powder," "0 added tea powder," and "0 added flavorings." It is reported that this series uses concentrated milk and carefully selected whole-leaf extraction, with cold-chain storage and transportation throughout, and the JD.com presale price is 135 yuan for 15 bottles. Looking back to the end of 2013, Nongfu Spring had launched a matcha-flavored Da Milk Tea in a tumbler-shaped bottle, which faded out after a lukewarm market response. Now, bottled ready-to-drink milk tea is regarded as a new outlet, and in the hundred-billion milk tea market, street drinks, brewed drinks, and ready-to-drink drinks each occupy a share, with new brands such as Genki Forest and Hankou Erchang also entering the fray. Front Street Coffee believes that whether Nongfu Spring can win consumers' favor this time remains to be tested by the market. [more…]

Good Mei's 8-yuan Good Morning Fresh Milk Sparks Debate: A Convenience Store Substitute or Just R&D KPI Padding?

Guming's mini-program has quietly launched a new product called "Morning Fresh Milk." The only ingredient is fresh milk, available in hot or cold options, priced at 8 yuan per 500ml. After trying it, consumers discovered that the cup contains exactly the same refrigerated fresh milk brands used in stores for making tea drinks—Yue Xian Huo, Weigang, and Renyangyitouniu—tasting no different from what's sold in supermarkets and convenience stores. Once the news broke, netizens reacted with sharply divided opinions: some felt the price was completely uncompetitive, arguing it's better to just buy from a supermarket or convenience store, and joked that this was "forcing out a product with no real substance," with R&D staff cobbling together a new item just to meet KPI targets; others thought they could simply add espresso or toppings themselves to make a low-cost latte. Some netizens even let their imaginations run wild, speculating that Guming is testing the waters for a foray into the breakfast market. This article will sort through the discussions sparked by this new product and the possible business logic behind it. [more…]

Luckin's Guangdong-Shenzhen limited light coffee series priced at 19.9 yuan is criticized for poor value, with consumers reporting bland taste and excessive ice

Recently, Luckin Coffee took the lead in launching two limited-edition iced drinks in Guangzhou and Shenzhen—Light Coffee Lemon Tea and Light Coffee Coconut Water—highlighting a refreshing tea-coffee concept with added raw coffee liquid and low caffeine. However, after the new products launched, the 19.9 yuan price and bland taste quickly sparked heated discussion among consumers. Many Guangdong netizens said bluntly that the taste of this drink is not much different from bottled lemon tea from convenience stores, yet it costs nearly twice as much, which is really hard to accept. Some even complained that ice cubes filled almost half of the extra-large cup, making them feel they had spent money on nothing. At the same time, Luckin fans in other cities expressed dissatisfaction with the regional-limited strategy and called for a nationwide rollout. This controversy over the new products' pricing, taste, and limited-edition strategy—is it a cautious move by Luckin to test the market, or yet another marketing move that disappoints consumers? This article will take you to find out. [more…]

Specialty coffee brand Blue Bottle Coffee is about to make its Beijing debut this weekend in the form of a limited-time instant coffee pop-up, teaming up with snowboard brand BURTON to create a two-day event at THE BOX Chaowai Youth Energy Center.

Since its founding in 2002, Blue Bottle Coffee has expanded slowly in mainland China, currently operating only 5 stores in Shanghai, and although it has registered a company for a formal Beijing store, it has yet to actually open one. This article will review Blue Bottle Coffee's Beijing move, netizens' reactions, and the brand's development history in China. [more…]

Can you brew drip bag coffee directly with milk? Testing the correct method for milk-brewed drip bags and convenient alternatives

Drip coffee bags have always been primarily brewed with hot water, but some coffee enthusiasts prefer a rich and smooth taste, so they try using milk directly to extract the drip bag, hoping to create a homemade version of a latte. Can milk really replace hot water to complete the extraction? Front Street found through actual testing that due to the high protein and lactose content in milk, its extraction capacity is far inferior to hot water. If the conventional drip bag brewing method is directly applied, it often results in a cup of coffee with a weak flavor or even sourness. To compensate for this deficiency, Front Street tried a method of first blooming with hot water, then injecting heated milk in stages, and provided bean selection suggestions for different roast levels. However, the test results showed that after the milk comes into contact with the coffee grounds, the fine particles swell and clog the filter bag, and the entire process takes up to twenty minutes, which is far from the original intention of the convenience of drip bags. So, what other more convenient options are there for those who want to drink drip bag milk coffee? This article will reveal them all. [more…]

Can you brew drip bag coffee directly with milk? A detailed look at test results and three milk coffee preparation methods

Brewing drip coffee bags directly with milk sounds like a convenient shortcut, but what problems come up in practice? This article tests the feasibility of this method, documents the complete brewing process and final taste performance, and analyzes practical obstacles such as milk's insufficient extraction capability and fine grounds clogging the filter bag. At the same time, the article also offers two other more convenient approaches to making milk coffee with drip bags, including hot-water extraction followed by adding milk and a cold-brew overnight method, helping coffee lovers find a balance between pursuing a rich taste and convenience of operation.

Can Drip Bag Coffee Be Brewed Directly with Milk? Testing the Correct Method for Milk Extraction of Drip Bag Coffee and Alternatives

Drip bag coffee has always been primarily brewed with hot water, but many coffee enthusiasts want to use milk to directly brew a latte. Milk's extraction ability is far inferior to hot water, and after heating, the proteins and lactose undergo changes, so directly applying conventional methods clearly won't work. Front Street once conducted a dedicated experiment: first bloom with hot water, then inject 75°C hot milk in two stages, and prioritize medium-dark roasted drip bags, such as Bird of Paradise, Queen's Estate, Golden Mandheling, Huilan, etc. If you prefer fruity acidity, Sipr, Big Belly Button, and Strawberry Candy are also good choices. However, testing revealed that after milk contacts the coffee, the fine particles swell and easily clog the filter bag, taking nearly 20 minutes in total, which contradicts the convenience that drip bags are meant to offer. This article will fully present this experiment and share a more effortless iced milk cold brew method, allowing you to easily achieve latte freedom. [more…]

Water Buffalo Milk Latte and Dirty: Can Milk Foam Latte Art, Sweetness, and Coffee Flavor Coexist?

Buffalo milk has long been a specialty dairy product in the Guangdong and Guangxi regions, and in recent years it has been increasingly used by coffee enthusiasts to pair with espresso. It contains higher levels of protein, fat, and calcium than regular milk, with a lower water content, making it sweeter and silkier to drink. So, is buffalo milk actually suitable for latte art? And what does it taste like in an iced latte or a Dirty? This time, Front Street Coffee selected the refrigerated fresh buffalo milk from the local Foshan brand Baifulu, paired with Front Street Coffee's classic blend coffee beans, to make three drinks: a flat white, an iced latte, and a Dirty. From milk foam texture and latte art performance to the flavor on the palate, we tested each one to see whether the combination of buffalo milk and coffee can achieve an effect where 1+1>2. [more…]

Is Lower TDS Water Always Better for Brewing Coffee? An In-Depth Look at ppm Standards and Mineral Water Choices

Many coffee enthusiasts, after purchasing equipment and beans, often overlook the critical impact of water quality on flavor. Tap water, filtered water, or purified water—different TDS levels will directly change the extraction results. From the perspective of Front Street, this article explains how calcium and magnesium ions influence the taste, why tap water tends to produce astringency, and why purified water leads to a hollow sensation. It also cites the SCAA standard of 75-250ppm along with practical recommendations, advocating the use of filtered or bottled water, and specifically mentions Nongfu Spring as a reference choice for daily brewing.

How to adjust coffee brewing water? A detailed explanation of the ratio of baking soda to magnesium sulfate and why tap water should be avoided in espresso machines

The water you use to brew coffee has a far greater impact on the final flavor than you might imagine. Tap water tends to have a high mineral content, which not only easily builds up scale on the inner walls of a coffee machine and hinders its normal operation, but also interferes with the extraction of coffee flavor. Drawing on Front Street's practical experience, this article first explains PPM and the criteria for judging soft and hard water, then explains why espresso machines should not use tap water directly, and afterward gives a hands-on demonstration of how to mix your own brewing water using baking soda and food-grade Epsom salt (magnesium sulfate), along with a brewing comparison against Nongfu Spring, for coffee lovers' reference.
