Which cocktail is served in a copper mug?

The Moscow Mule is traditionally served in a copper mug, which is one of its signature features. The choice of copper for the mug not only adds a distinctive and appealing visual element but also enhances the cocktail experience by keeping the drink colder for a longer time. The combination of vodka, ginger beer, and lime juice in the Moscow Mule creates a refreshing beverage that is often associated with the unique presentation in a copper vessel. The other options, such as the Mojito, PJ Margarita, and Huckleberry Mojito, typically do not use copper mugs and are instead served in different types of glassware that are more suitable for their specific ingredients and presentation styles.
