Perfect for everyday use and an amazing value at 8 glasses for the price of 6, the eight extra-large red-wine glasses in this set are part of the moderately priced Ouverture series offered by world-renowned wineglass maker Riedel Crystal. Made of lead-free crystal and machine blown, these glasses are dishwasher-safe. Their thin rims are cut and polished to Riedel"s exacting standards, so wine flows easily onto the palate. Each glass stands 7-7/8 inches high, and their large bowls help release the wine"s aroma for full enjoyment. Though glasses shaped and sized for different types of wine seem a tradition today, Riedel was the pioneer of this revolutionary concept, which has created a lasting effect on the globe"s wine culture.
