Squeeze in the lime juice and then add the gin and ginger beer.
Give it a quick stir, garnish with lime wedges or wheels if using, and serve.

Notes
Use a ginger beer you like. Jamaican-style ginger beer from my grocery store has a spicier ginger kick.Use lots of ice and serve in a copper mule for a cold and refreshing drink.Customize your drink by adding different juices like cranberry juice, or other simple syrup like a jalapeno simple syrup for a bit of heat.
