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…]

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…]

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.

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…]

In a cup of black coffee, water accounts for over ninety percent, and whether it participates in extraction or is used for dilution, water quality directly influences the coffee's final flavor and mouthfeel. So, what kind of water is most suitable for brewing coffee? Can Nongfu Spring do the job? This article, from Front Street Coffee's perspective, first discusses the role of calcium, magnesium, and other ions in water in dissolving flavor, then combines the hardness standards of the World Health Organization and the SCA to explain the pros and cons of soft water, hard water, and purified water, and finally extends to the making of Americano to see what role water plays in the dilution stage. After reading, you will have a clear and practical judgment about what water to use for brewing coffee. [more…]

In a cup of black coffee, water makes up the vast majority, so its impact on flavor must not be underestimated. Different brands of drinking water vary in mineral composition, hardness, and pH, so the coffee brewed with them naturally takes on different characteristics. To investigate this variable, Front Street Coffee selected four common drinking waters—Baisui Mountain, Nongfu Spring, Ganten, and C'estbon—and used the same Costa Rica Mozart coffee beans to make cold brew, measuring TDS, coffee liquid concentration, and recording flavor performance one by one. The experiment found that the amount of calcium and magnesium ions in water affects extraction efficiency and taste direction, while Nongfu Spring with medium TDS and C'estbon purified water each showed distinct stylistic differences. This article will present the full experimental process and tasting results, and offer water selection suggestions for different taste preferences. [more…]

As the primary raw material, water not only makes up the vast majority of a cup of black coffee, but also influences the extraction of different substances, thereby producing distinct flavors and mouthfeel. Therefore, all of us should understand the importance of water to coffee. Common drinking water on the market varies from brand to brand, in the ingredients it contains, and in its purification processes. [more…]

Robust, once part of a "three-way split" in the drinking water market alongside Wahaha and Nongfu Spring, has recently re-entered the bottled water race with 1-yuan mineral water, drawing market attention. This veteran company, founded in 1989, has seen its presence dwindle after going through twists and turns such as being acquired by Danone and having its brand change hands. Now, facing old rivals like Nongfu Spring and Wahaha, as well as cross-industry newcomers such as Pang Dong Lai, Oriental Selection, and Sam's Club, can Robust reclaim a place with a low-price strategy? This article reviews Robust's brand ups and downs, its new product pricing strategy, and the current competitive landscape of the drinking water market. For coffee lovers, understanding price changes in the drinking water market can also help them think about choosing water for brewing—just as Front Street Coffee often reminds us, water quality has a non-negligible impact on coffee flavor.

Water is the largest component of black coffee and directly participates in and influences the extraction process, so differences in water quality often bring about completely different flavor expressions. There are many types of bottled water on the market, with prices ranging widely from high to low, and whether more expensive water is more suitable for brewing coffee has become a question for many brewing enthusiasts. This article uses two types of bottled water with明显 price differences as test subjects, and adds Nongfu Spring, commonly used in stores, as a control, conducting blind tasting comparisons with two coffees, Yirgacheffe Red Cherry and Diamond Mountain. At the same time, from the perspectives of acidity and alkalinity, softness and hardness, TDS, and calcium and magnesium ions, it explains the principles by which water quality affects extraction, helping coffee enthusiasts understand how to choose more suitable water for brewing coffee.

On February 6, 2023, Wahaha launched a new ready-to-drink coffee product called "Kawei," offering two flavors: Fresh Latte and Raw Coconut Latte, highlighting selling points such as imported milk sources and Arabica beans. This marks Wahaha's re-entry into the ready-to-drink coffee sector after the failure of its Maoyuan Coffee in 2016. However, the current ready-to-drink coffee market is already crowded with giants like Nestlé, Starbucks, Coca-Cola, and Nongfu Spring, and products are highly homogenized. Wahaha's entry at this time puts it years behind its competitors, and the market landscape has long since changed. This article reviews Wahaha's coffee attempts, the company's sales background, and the competitive dynamics of the ready-to-drink coffee market to explore the prospects of "Kawei." [more…]

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.

As consumer demand for coffee becomes increasingly routine and health-oriented, major brands are facing new market challenges. Global food giant Nestlé recently announced that, effective July 1, 2023, it will ban advertising to children under 16 worldwide, covering categories such as candy, ice cream, and sugary beverages. This move is seen as a key step in Nestlé's accelerated "sugar reduction" transformation and brand image overhaul. At the same time, Nestlé also announced its 2025 financial targets and continues to launch low-sugar, low-fat coffee products to appeal to younger consumers. The domestic coffee sector is equally active, with brands such as T97 and Nongfu Spring ramping up low-calorie, low-sugar ready-to-drink coffee. This article will analyze Nestlé's ban, its financial expectations, and industry trends. [more…]

The Henan Provincial Market Supervision Administration recently published its 2024 No. 39 food safety notice, showing that of 1,040 batches of food across 21 major categories sampled, a total of 24 batches failed. Among them, a "Yangtze River North Bank" oolong tea-flavored beverage, nominally produced by Xunxian Fuxinyuan Beverage Factory, was blacklisted because its total bacterial count did not meet national standards. An investigation found that the manufacturer not only had a prior record of product sampling failures, but was also ruled by a court to have infringed upon Nongfu Spring's packaging through counterfeiting, and has now been listed as a dishonest judgment debtor. More notably, the outer packaging of this oolong tea is highly similar to Suntory oolong tea, and many consumers who mistakenly bought it on e-commerce platforms complained loudly after being duped.

Suning Xiaodian's first dedicated coffee shop has begun trial operations in Nanjing, marking Suning's official move to step up its presence in the coffee market. The store adopts a "convenience store + coffee" model, offering 27 beverages across five major categories, including coffee, tea drinks, and frozen treats, with prices ranging from 12 yuan to 28 yuan. Leveraging the network advantages of more than 5,000 Suning Xiaodian stores nationwide and operational data within a three-kilometer radius, Suning Coffee has clear competitiveness in customer acquisition and daily operations. This is also Suning's fourth format for expanding coffee consumption scenarios, following vending counters, express delivery, and unmanned self-service machines. As players such as Mengniu, Nongfu Spring, Coca-Cola, Sinopec EasyJoy, and OYO successively enter the market, the battle for the coffee market has gained another variable. [more…]
