The specific choice of serving a Moscow Mule in a copper vessel is a practice deeply rooted in both marketing and historical accident, but also possesses properties that enhance the overall drinking experience. A key component to consider is the material composition of the mug, pure copper, and its interaction with the beverage.
The tradition stems from the drink’s origin in 1940s Los Angeles. A liquor distributor struggling to sell Smirnoff vodka, a bar owner with excess ginger beer, and a woman trying to promote her copper mugs converged. The copper mug provided a distinctive visual appeal, aiding in marketing the novel cocktail. Furthermore, the cold copper intensifies the perceived chill of the drink, heightening the refreshing sensation. Some believe the copper enhances the aroma and effervescence due to an interaction with the drink’s ingredients.
