The durable machine-made Riesling and Zinfandel glass of the functional glass collection Wine features a light-catching, decorative stem. The shape of the glass best supports the characteristic bouquet of fruity red wines or floral white wines – aroma and taste are dominated by fermented grape juice and the flavor of yeast. This special collection was created for customers, who feel that plain stemware on a well laid table is just not decorative enought. All RIEDEL glasses are dishwasher safe.
