Wine drinking out of stainless steel cups

[Jackie]

Metal transmits heat faster, so wine would warm up faster in metal, I would think, than in glass. Stemware was invented so that wine would stay cooler, since the glass could be held by the stem and no heat would be transmitted from a hand cupping the glass. Personally, I have some "chunky" style wine glasses that I love because they are not fragile and delicate but still have a stem to hold the glass without heating the wine. I think I got them from Pottery Barn years ago... and not one has ever broken.

Metal would also affect the taste, I think, of many wines. But I don't have a scientific explanation for that. Anyone??
