A Coffee Shop Owner's Fight for Justice: Bought a La Marzocco PB from an Acquaintance Only to Find It Was Grey-Market, and After the Boiler Burst, the Official Records Showed No Such Machine

A coffee shop operator in Guangxi recently publicly recounted his experience: he purchased a La Marzocco PB espresso machine from a well-acquainted "coffee champion," and after only one year of use, the boiler exploded. When he applied to La Marzocco China's official after-sales service, he was told that the machine had no record in the system and was a "grey import" sold through unofficial channels. The shop owner believes the other party deliberately concealed the sales channel, and has sent a lawyer's letter and reported the matter to the police. This dispute quickly fermented within the coffee community and also drew practitioners' attention to how to distinguish genuine La Marzocco espresso machines from grey imports.

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.
