These Vinum Sauvignon Blanc glasses are made of 24-percent lead crystal by Riedel, makers of fine glassware. Wine connoisseurs will particularly appreciate the care and design that goes into making sure each Vinum glass is the perfect shape for enhancing the bouquet and flavor of specific varietals. The distinct bowl shape directs the wine to a specific area on the palate, so each note can be appreciated and savored. Both simple, yet elegant, these stems complement any dinnerware pattern.
