Refreshingly delicious and classic, the Moscow Mule has become a staple on cocktail menus across the country. The simple three ingredient cocktail - vodka, lime, and spicy ginger beer is a perfect pick-me-up on a Spring or Summer evening, generally served in an iconic copper mug initially presented in the 1940's by the Moscow Mule's originator, John G. Martin. Since then the mug has experienced a comeback at restaurants and bars, and for good reason. Copper, being a strong natural conductor keeps drinks colder (or hotter) longer than your average glass tumbler, perfect for a drink to stay icy fresh. We love Bar Atelier's hammered copper version with a sturdy brass handle. Available in sets of two, these mugs make a great gift and a confident addition to your bar cart. Try them out for yourself and see what the rage is all about, $64/set. Available online and in store.
