Ask Wine Wizard
Henry Urick — Castaic, California asks,
In a discussion at our CellarMasters wine club, one person said that using copper preventively introduces unnecessary heavy metals and could destroy beneficial volatile acids. Another person observed that most of our homes are full of copper piping and this is not recognized as a heavy metal hazard. We all agreed that there is a huge difference between the water in our pipes and wine, which is substantially more acidic, is a solvent and has more potentially reactive properties. In any event, where do you weigh in on this subject?
