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.
