What better way to serve the timeless Moscow Mule than in an Old Dutch Moscow Mule Mug? The Moscow Mule is a classic cocktail usually served in a copper mug that has been refreshing taste buds since the 1940's. That famous blend of vodka, ginger beer, and lime juice can be enjoyed, especially so, with these new Hammered Solid Copper Moscow Mule Mugs. Featuring an attractive hammered finish to please the eye, each mug is also made of 100% Copper, which not only keeps your drink cool, but brings out the flavors of your mule recipe. For the purists, each mug is unlined and unlacquered, leaving nothing between you and your copper vessel.
