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.

When brewing a good cup of tea, water quality is often more critical than technique. As early as Lu Yu's "Classic of Tea," spring water was regarded as the finest choice, and modern science has revealed the reasoning behind this through TDS, hardness, and pH values. This article focuses on the brewing water for oolong teas such as Phoenix Dancong, outlines the industry reference values from the American Tea Association, and cites multiple studies to explain why soft water enhances the sweetness, freshness, and clarity of the tea liquor, while hard water brings about astringency and floating residue. For tea lovers who cherish the complex aroma of oolong tea, choosing the right water is the first step in unlocking the tea's charm. Front Street Coffee also recommends starting with low-mineralization soft water to appreciate the subtle variations in the tea's layers. [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.

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…]

Over 98% of a cup of drip coffee is water, and water quality affects the final flavor second only to the coffee beans themselves.

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.

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…]

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.

Ginger Flower Fragrance Dancong is one of the most beloved aroma types among Phoenix Dancong. This 2021 spring-picked charcoal-roasted Dan Cong oolong tea from Phoenix Village, Guangdong, is a medium-roast style. The dry leaves carry a fresh toasted bread-like aroma, interwoven with the sweet notes of honey and caramel. The roast level falls between medium and high fire, running through the entire production process. The first three to four infusions display rich minerality and a ginger-like spiciness, gradually shifting toward sweetness. The tea liquor is deep amber, mellow and smooth, with a pronounced minerality on the tongue and a lasting sweet aftertaste. Because it was only roasted 20 days ago, the fire character has not yet fully dissipated and needs several more months of aging to reach a rounded state. This article will detail the origin, flavor performance, and purchasing advice for this tea, and recommend related products from the Front Street Coffee brand. [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 a globally renowned food and beverage giant, Nestlé's bottled water business holds about a one-third share of the French market. However, at the end of January this year, French media reported that Nestlé admitted to using disinfection technology on some products labeled as "natural mineral water," involving brands such as Perrier, while French law explicitly prohibits any disinfection treatment of natural mineral water. Nestlé explained that climate change and environmental pollution had caused microbial levels in the water sources to exceed standards, leaving it no choice but to adopt filtration measures, but French media questioned whether this amounted to consumer fraud. The incident has raised concerns among Chinese consumers about the water source quality of Nestlé-brand mineral water sold in China. Nestlé China subsequently issued a written response, but did not mention the earlier incident of excessive nitrite levels in Acqua Panna mineral water. Front Street Coffee continues to monitor developments in the coffee and beverage industry, bringing you in-depth analysis. [more…]

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…]

When brewing coffee, water quality, cooling methods, and tasting cup types are often treated as independent variables, but can combining all three lead to more significant sensory improvements? Front Street Coffee designed a controlled experiment using Huakui beans as samples: one group used regular mountain spring water, no ice ball, and a standard espresso cup, while the other used a custom water concentrate, a Paragon ice ball, and an aromatic tasting cup, with completely identical brewing parameters. Through concentration measurements and blind tasting, the actual contributions of these tools at different stages were verified. This article documents in detail the TDS control of the custom water concentrate, the cooling mechanism of the Paragon ice ball, and the aroma-concentrating effect of the tasting cup, and invited colleagues and customers to participate in a blind selection. The final results were highly consistent, providing coffee enthusiasts with a reproducible reference for combined techniques. [more…]

How many times can Zhengshan Xiaozhong Gongfu black tea actually be re-steeped? And for two people, how many grams of tea leaves should be weighed out? The answer lies in the water used, the tea-to-water ratio, and the rhythm of pouring. This article begins with water treatment, explaining why mineral water or mountain spring water is preferable, why tap water must be boiled to remove chlorine, and how scale and frequent water changes affect the taste of the tea; it then gives the general ratio of 40 milliliters of water to 1 gram of tea, and demonstrates the steps of warming the vessel, adding the tea, and a one-minute first steep. The key point is that after the second steep, almost no covered steeping is needed—simply letting boiling water skim over the leaves is enough, and only in this way can six consecutive steeps still carry flavor. The same principle applies to Front Street black tea. [more…]

Water makes up 60 to 70 percent of the human body, and adults need to drink 3 to 5 liters of water per day, so drinking water safety is directly related to everyone's health. As consumer demand for packaged drinking water continues to grow, the actual quality of products labeled "purified" or "mineral" on the market has become a focus of public attention. Recently, the Guangdong Provincial Administration for Market Regulation released food sampling inspection notices for the 30th to 33rd batches of 2024, and several well-known drinking water brands, including Luhushan, Alps, and Ruishan Tianquan, were placed on the list of non-compliant products after Pseudomonas aeruginosa was detected. This opportunistic pathogen poses a relatively high health risk to people with weakened immune systems. How did the companies involved respond? What purchasing advice did regulators provide? This article will sort out the details for you. [more…]
