A Moscow mule is a cocktail made with vodka, spicy ginger beer, and lime juice, garnished with a slice or wedge of lime and mint leaves.
The most scientific benefit of using copper Moscow mule mug is temperature. Chilled drinks in copper cups offer an extra-cool sensation, due to the metal quickly taking on the icy temperature of the cocktail.
PREPARATION FOR A MOSCOW MULE
In a cocktail shaker three-quarters filled with ice, combine vodka and lime juice and shake until chilled, about 15 seconds. Strain into a mug, preferably copper, filled with crushed ice. Top with ginger beer. Garnish with lime.
