Their design is a classic for serving iced cocktails such as the Moscow Mule, a blend of vodka, ginger beer and lime juice and can be used for any iced beverage. The metal helps keep cocktails and other refreshments well chilled. Copper mugs helps to make your Moscow Mule and other beverage feel super chilling in hot summer. The cold metal is highly effective at insulating the cold temperature of any liquid, especially good for summer time drinking, and deflecting heat from the sun. Copper has a very high thermal conductivity so the coldness from your Mule will fly into your hands, lips and throat at an amazing rate. It will feel exactly as the icy drink. This is not possible to get that from a high ball glass drinkware. Copper mugs have become an essential ingredient for Moscow Mule. So many people claimed that the Mule they made at home feel not right as they experienced in bars, and found the copper cups were the source of that.
