In a copper mug, add ice, followed by the gin and lime.
Top with ginger beer and garnish.
Notes
Use fresh lime juice for the BEST flavor. Variations
Use flavored gin - as long as the flavors work with lime and ginger, flavored gins are a great way to add another element to this simple Gin Mule!
Add fresh mint - for a slightly herbal flavor, muddle fresh mint leaves in the bottom of the glass with the gin before adding the ice. Then garnish with a fresh mint sprig! Add a splash of simple syrup too and you'll have made a classic Gin-Gin Mule.
Go low - you can easily make this cocktail 0% by using one a zero-proof alcohol alternative. I really like Ritual Gin.
