Experts with the world's most discerning palates helped develop Riedel's Vinum series.  These six elegant lead-crystal glasses showcase the best qualities of full-bodied red wines, especially Bordeaux.  The generous bowl allows the bouquet to develop fully.  The tapered rim directs the flow of wine to the tip of the tongue, which perceives sweetness, allowing you to appreciate a harmonious balance of fruit flavors and supple tannin.  Salut!
