Copper Cocktail Mug

A copper cocktail mug is the traditional vessel for the Moscow Mule, and this Esplanda-branded one is made for that job. The listing doesn't give a capacity, lining or finish, so check those details on the product before you plan around them. Copper mugs of this type usually hold about 14 to 16 ounces, which is enough for ice, a standard pour of spirit and a tall measure of ginger beer. Copper conducts temperature quickly. Chill the mug in the freezer or fill it with ice and water for a few minutes before building the drink. The metal then carries the cold to your hand and lip, and the ice melts more slowly. Crushed or pebble ice suits the mug best, since it packs the cavity and keeps the drink cold to the last sip. The Moscow Mule is the obvious first drink: vodka, fresh lime juice and a sharp, spicy ginger beer, finished with a lime wedge and a mint sprig. The same build works with other spirits. A Kentucky Mule uses bourbon, a Mexican Mule uses tequila, and a Dark 'n' Stormy-style drink uses dark rum with ginger beer. Gin and aged rum both work well here because their botanical and caramel notes sit well against ginger heat. Any long, ice-heavy highball or julep-style drink will also suit the mug. Most copper mugs are unlined or lined with nickel or stainless steel, and a lining matters for care. Unlined copper reacts with acidic ingredients such as citrus, so follow the maker's guidance on whether to serve acidic drinks in it. Wash by hand with mild soap, dry it right away, and avoid the dishwasher, which dulls the finish. A paste of salt and lemon juice or vinegar will restore shine if the exterior tarnishes.
