Experts with the world's most discerning palates helped develop Riedel's Vinum series, a glassware collection designed to flatter specific types of wines and liquors. Showcasing the best qualities of single malt and other whiskeys, these elegant glasses were created with extensive input from master Scottish distillers. Machine-made of brilliantly clear crystal glass. Bowl's elongated thistle shape brings out the aromas of fine whiskeys. Flared lip directs the flow of liquid to the tip of the tongue, allowing you to savor the whiskey's smooth, silky texture. Made in Germany by Riedel, a family-owned company since 1756.
