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…]

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.

Water accounts for over 98% of brewed coffee, yet it has long been overlooked. Different types of water—RO water, tap water, mineral water, soft water, hard water—have a huge impact on extraction flavor. In 2014, Christopher Hendon and Maxwell Colonna-Dashwood published research revealing how sodium, calcium, and magnesium ions influence the extraction efficiency of flavor compounds, and subsequently published the book "Water for Coffee," which systematically discusses the dynamic balance between GH (total hardness) and KH (carbonate hardness), and proposes the reverse thinking of "Roasting to water." This article will sort out these key findings to help coffee lovers understand how water quality shapes the flavor in the cup, and will retain relevant recommendations for the Front Street brand.

When brewing a pour-over coffee, water accounts for up to 98.7%, making its importance no less than that of the coffee beans and grinder.

It also uses examples to explain how, when coffee develops off-flavors or negative mouthfeel, you can troubleshoot the problem by switching water sources such as Nongfu Spring, helping enthusiasts on a limited budget spend their money where it matters most.

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…]

The final flavor of a cup of coffee depends not only on the beans themselves—every variable in the brewing process is quietly rewriting the taste. Water quality is the foundation: hard water or water with high iron content will directly drag down the flavor; water temperature needs to be controlled between 80°C and 90°C, as boiling water only lets bitterness steal the show. Steeping time is equally critical, with around two minutes being the ideal range; steep too long and the aromatic oils are destroyed, while a cloudy film also rises to the surface. The material of the equipment cannot be ignored either: glass and ceramic are safe choices, while metal vessels easily trigger oxidation reactions and bring unpleasant flavors. As for the dosage, it should be adjusted flexibly according to grind size and personal taste—coarse particles often require a bit more than fine ones. Only by mastering these key points can the coffee's aroma and layers be released steadily. [more…]

When brewing pour-over coffee, water quality is one of the key variables that determines flavor expression. This article focuses on the two core indicators of water: hardness and pH, explaining the TDS range recommended by the SCAA as well as the water quality range that more easily yields good taste in actual brewing, and explaining the effects of calcium and magnesium ions on coffee acidity, sweetness, and aroma. The article will also analyze one by one whether tap water, filtered water, purified water, and mineral water are suitable for brewing coffee, reminding readers to pay attention to the TDS and mineral content on labels, and to avoid judging water quality based on price alone. Finally, it offers practical advice on water for daily brewing to help coffee enthusiasts reproduce coffee flavors more consistently. [more…]
