The tradition of serving Moscow Mules in copper mugs stems from a confluence of marketing ingenuity and the unique properties of copper. Originally, the drink was created in the 1940s as a way to popularize both vodka and ginger beer. The distinctive copper mug became a key element of the drink’s identity, visually setting it apart from other cocktails.
Copper enhances the sensory experience of the Moscow Mule in several ways. The metal’s high thermal conductivity rapidly chills the drink, creating a frosty mug and an icy, refreshing sensation. Copper also reacts with the lime juice in the cocktail, subtly altering the flavor profile. This reaction adds a distinct tartness while potentially reducing the metallic taste sometimes associated with ginger beer. The visual appeal of the gleaming copper mug further elevates the drinking experience, adding an element of elegance and tradition. Furthermore, the copper mug contributes to the characteristic fizziness of the Moscow Mule by helping to maintain carbonation.
