To make a Moscow mule, pour 1/2 ounce of freshly squeezed lime juice into a Collins glass. Add a couple ice cubes, 2 ounces vodka, 4 to 6 ounces ginger beer and the used lime. This drink is served with a stirring rod.
The Moscow mule was originally created in 1946 in Hollywood, California. John G. Martin, whose employer Heublein Inc. had bought the American rights to Smirnoff vodka, was sitting in a bar called the Cock 'n' Bull. The pub's owner was bottling his own brand of ginger beer, but customers were not interested in drinking it. Martin also had a problem drumming up business for the newly acquired liquor. Together they came up with the Moscow mule. The original was served in a copper mug.
Through the years, the Moscow mule has undergone some tweaks, and many variations now exist for the classic vodka drink. Keeping ginger beer and vodka as the base for the drink, different herbs and fruits are added to create a refreshing cocktail that is enjoyed year round. For example, a mule with apple cider and a cinnamon stick has great fall flavors, and one with peaches and ginger is enjoyed in late summer.
