Fill a copper mug or tall glass with ice cubes.
Pour 2 ounces of vodka over the ice.
Add 1/2 ounce of fresh lime juice.
Top off with ginger beer, pouring slowly until the glass is full.
Gently stir once or twice with a long spoon to mix without losing the fizz.
Garnish with a lime wheel and a sprig of fresh mint.
Serve immediately and enjoy.
