1 oz vodka--whatever your favorite brand works
1/2 oz lime juice--I always recommend fresh squeezed
Ginger Beer--for those who don't know this amazing drink, ginger beer is not in fact a beer but a soda. More along the lines of root beer. Depending on what brand you buy it can be very tangy and spicy. You might want to try a few different brands to find your favorite. We prefer Fever Tree.
Traditionally the Moscow Mule is served in a copper mug. We use rocks glasses. Add all the ingredients over ice, stir, finish off with a lime wedge and enjoy. I think you'll like this one.
