Time to break out the copper mug.  This simple yet memorable drink is made with vodka, ginger beer and lime juice. 

Ingredients

• Juice of one lime
• 3 Ounce Russian Standard Vodka
• 6 Ounce cold ginger beer (not to be confused with ginger ale)
• 3 Drops Angostura bitters
• Twist of lime, for garnish

Preparation

Step 1:

In a Collins glass — or a copper mug, if you own one — squeeze the juice of one lime and fill with crushed ice.

Step 2:

Pour the vodka and stir. Fill the glass with cold ginger beer. As for the bitters, according to César Raúl Córdova Rogerone— a Moscow Mule connoisseur — it works better if the bitters sort of float on the surface and make their way slowly to the bottom of the glass, leaving a lovely hint of smoke on the way down. You won’t get this visual effect if you use a copper mug, of course, but the bitters are still worth every drop.

Step 3:

Garnish with a twist of lime.
