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…]

Regarding what water to use for brewing coffee, there has long been a popular saying: "Don't use purified water." Does this claim actually hold up? Water quality really does influence how coffee flavors express themselves, and purified water is called into question mainly for two reasons: first, its extraction efficiency is on the low side, because the water lacks calcium and magnesium ions to help dissolve flavor compounds; second, purified water has poor conductivity, which can cause the boiler probe in a coffee machine to malfunction, leading to abnormal refilling or even breakdowns. Through comparative experiments, Front Street found that coffee brewed with purified water versus mineral water shows only slight differences in concentration and extraction yield—hard for an ordinary person to notice. What is truly unsuitable for brewing coffee is hard water with a TDS above 175 ppm. This article will analyze these points one by one and offer water-quality recommendations for everyday brewing.
