As all good mixologists know, the cocktail, Moscow Mule was the way vodka was introduced into America in the 1940s. By the 1950s it was all the rage. Today, it is the #1 selling spirit in America. Three men were responsible for it's creation and marketing a special copper mug for it as well. Our replica 100% copper mug hammered holds 16 oz. Impress your friends with these stylish, hand-crafted copper mugs! Moscow Mule 2 oz vodka (Smirnoff to be authentic) 6 oz ginger beer ½ oz fresh lime juice Lime garnish Fill the mug with ice and add the ingredients. Stir. Why use Pure Copper? Pure copper is essential for the chemical ionization of acids found in citrus fruits such as limes, lemons, and oranges. For this reason, other mugs that have stainless steel linings or nickel do NOT have the same taste as drinking from a pure copper mug. At A29, we take great pride in the authenticity and craftsmanship of our products. Your new Moscow Mule mug is made from 100% copper without any lining. Don't drink from a cheap imitation you deserve better. Care Tips: (A) Clean your copper mugs by hand and avoid dishwasher as the detergent can damage the lacquer coat leading to permanent damage to the mug. (B) Since the inner surface of the mugs is unlined and made of 100% pure copper, it may tarnish over time. Use any copper cleaner cream to restore shine. You can also use a home-based remedy of a solution of equal quantities vinegar / lemon juice and salt, diluted with some water. Avoid scratchy cleaners like steel wool to clean your mugs.
