Created in the 1940s by entrepreneurs Jack Morgan and John G. Martin, the Moscow Mule was served in specially engraved copper mugs to market vodka to Americans. Ever since, the cocktail has been a spicy and refreshing favorite year-round.

Add vodka and lime juice to a chilled mule mug filled with crushed ice—the colder the mug, the better. Top with ginger beer and garnish with a lime wheel and mint.

Tip: Keep your vodka and ginger beer sufficiently chilled before making this classic drink.
