As a bartender my favorite to make and drink is the classic Moscow Mule. Its simple and requires only a few ingredients that you can purchase at your local grocery store. If you aren't like me with a full bar conveniently located in your living room you can used a basic rocks glass.
For a little bit of bar science, the copper cup is a superior thermal conductor, therefore the mug will respond to the temperature of whats inside. The copper mug will become cool creating a chilling sensation when sipped. Additionally, the cold copper intensifies the fizziness of the carbonation from the ginger beer creating refreshing and aromatic sips. Moscow Mule purists, like myself say that the copper cup enhances the flavors of the spiciness of the ginger beer and the citrus in the lime.
Enjoy! And please drink responsibly.
