Old Dutch International specializes in Artisan-Crafted Copper and is the purveyor of “The Original Moscow Mule Mug”. The Moscow Mule is a cocktail comprised of ginger beer, vodka and lime juice which first became wildly popular in the 1940’s. Fueled by recent celebrity endorsements, this refreshing and easy to make cocktail has once again become one of America’s favorite libations. Invented at the Cock ‘n’ Bull Tavern, the Moscow Mule is served in a copper mug, to increase its prestige and distinguish it from more mundane cocktails. Ideally, these mugs are made of solid copper, which keeps your drink cooler longer. Original Old Dutch Mugs are made of high-grade materials and feature exteriors sealed with a non-tarnishing clear finish.
