The Moscow Mule is a refreshing and zesty cocktail that is made with vodka, ginger beer, and lime juice. This popular drink is typically served in a copper mug, which helps to keep it cold and enhances the flavors. The vodka provides a smooth and neutral base, while the ginger beer adds a spicy and effervescent kick. The lime juice adds a tangy and citrusy flavor. The combination of these ingredients creates a well-balanced and invigorating cocktail that is perfect for any occasion.
