Professor Claus Riedel recognized that bouquet, taste and balance of wines are affected by glass finish and shape. Riedel's Vinum series, crafted of machine-blown lead crystal, offers a specially designed glass to achieve full expression of each wine varietal. Vinum Sauvignon Blanc was created for light-bodied white wines with higher acidity. Its small, delicate bowl, almost-straight sides and thin polished rim present a light, fresh wine at its best. A treasured gift for lovers of Sauvignon Blanc, Sancerre, Fumé Blanc, Semillon. The preferred glassware of top wineries and restaurants around the world.
