<< Btw, lead ions are almost without flavor. >> Yes, but lead like most metals can act as a catalyst, giving it an effect out of proportion to the concentration. << it takes a fair bit of lead to be genuinely toxic. It ain't plutonium or PCBs.>> Be glad. This much plutonium and we all would already be dead. But lead is very very serious. Probably any level of lead over parts per trillions is toxic to some degree. You can't say the body has absolutely no use for heavy metals, but it's close. When heavy metals get in the body they substitute for calcium and other light metals in our chemistry, to our detriment. Plus contribute to cross-linking and DNA damage. CNS effects from repeated exposures take place from parts per billion. A couple of people have said that if the wine is not in the glass long there would be less of an issue. I remind you that lead poisoning is cumulative, and can build up over a period of months. So the five minutes from one glassful adds to the five minutes for the next. Or whatever amount of time you take. Not only that, but if the glass sits on the table for a while with some wine wetting the glass in between glassfuls, leaching is occurring the entire time you are drinking, which can be up to several hours. Most people don't wash the glass between glassfuls, I presume. The points people made about the shape of the glass are interesting. I agree vapor concentrations also can affect taste. I overstated my case there. However, you can buy lead-free, even cheap glasses made of pure glass to get the same effect. Be careful with your health. Wine drinkers are already suffering under enough delusions about the overall healthiness of alcohol and 'heart-healthy' wine without needlessly adding lead poisoning to the mix. I'm not saying don't do it, of course. I drink wine, but the 'good' glasses stay on the shelf these days. One can at least be smart and only drag those glasses out for special occasions. Cheers, Chaz
