Riedel Crystal Champagne Glasses: Introduced in 1986, Vinum was the first machine-made series of glasses in history to be based exclusively on the characteristics of quality, reasonably price and wide distribution. Vinum has had a permanent impact on the globe's wine glass culture. These glasses have proved to consumers and restaurateurs that the pleasure of consuming wine starts with the glass. The Vinum collection, developed by Georg Riedel on the principle that the content commands the shape, is the "Vitrum-Vinothek" for every day use. Vinum is made of over 24% lead crystal.
