Riedel Ouverture Magnum Glasses, Set of 4
Perfect for everyday use, the four extra-large red-wine glasses  in this set are part of the moderately priced Ouverture series offered  by world-renowned Austrian wineglass maker Riedel Crystal (founded in  1756). Being lead-free, they're not crystal like Riedel's premium  glasses but are machine blown of potash glass and are dishwasher-safe.  Their thin rims are cut and polished to Riedel's exacting standards, so  wine flows easily onto the tongue. Each glass holds 18-5/8 ounces and  stands 7-7/8 inches high, and their large bowls help release a wine's  aroma, concentrating it in the narrower tops for full enjoyment. Though  glasses shaped and sized for different types of wine seem commonplace  today, when Riedel introduced this idea in 1961, it was revolutionary.  Since then Riedel has continued fine-tuning glasses to bring out the  best characteristics in wines and spirits. Varying bowls' shapes and  sizes affects the position of the head when sipping and where wine  first contacts the tongue's various taste zones.--Fred Brack
