What Water Should You Choose for Brewing Coffee? Why Purified Water Is Not Recommended for Coffee Machine Extraction

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.

SF Intra-city system suddenly malfunctioned, causing widespread disruption to Starbucks and Luckin delivery services.

This morning, delivery orders for Starbucks and Luckin Coffee experienced widespread disruptions, with many consumers waiting in vain for riders to pick up their orders after placing them on Ele.me and the brands' official channels.
