Why Is A Moscow Mule Served In A Copper Mug?
A Moscow Mule is served in a copper mug because it helps to keep the drink cold for longer periods of time. Copper is an excellent conductor of cold temperature and when the cold from the drink is transferred to the copper mug, it tends to stay cooler for a longer period of time. Additionally, the copper mug makes for a unique presentation and has become a signature characteristic of the Moscow Mule cocktail.
