Our copper cups feature a smooth lip that lets you drink in comfort, unlike the sharp edges found on other mugs. Moscow Mules enhance the individual flavors of the ginger beer, vodka, and lime. Some experts say that when vodka touches the walls of the mug, the copper begins to oxidize, slightly boosting the aroma, and enhancing the taste of the vodka. Cold copper also has a tendency to increase the amount of bubbles in the carbonated ginger beer, bringing maximum fizziness to the Moscow Mule, when compared to being served in a plastic or glass container.
