Austria's Riedel is the world's premier manufacturer of wine glasses. Made of 24-percent lead crystal, the Vinum series of glasses are the first machine-made wine glasses to be developed uniquely for each type of wine. Since their introduction in 1986, these wine glasses have had a large influence on the wine culture. The glasses in this set of six were specifically shaped to highlight the tannins in wines made from the Australian Shiraz variety of grape, such as Amarone, Blaufrankisch, Chateauneuf-du-Pape, Grenache, Hermitage Rouge, Malbec, Mourvedre, Pinotage, Shiraz, and Syrah. The glass shape also provides balance to the intense flavor of this very concentrated wine. Each glass stands 9-1/4 inches high and holds 22-7/8 ounces of wine. --Cristina Vaamonde
