The Moscow Mule is a vodka-based cocktail that is typically served in a copper mug. It is made by combining vodka, ginger beer, and lime juice. This zesty and effervescent drink gained popularity in the 1940s and is often associated with a refreshing and tangy flavor. The combination of vodka's neutrality, the spiciness of ginger beer, and the tartness of lime juice creates a crisp and invigorating cocktail that is perfect for any occasion.
