Add the bourbon, lime juice and a handful of ice to a copper mug. If you don't have a copper mug, you can use a highball or double old fashioned glass.
Using the bar spoon stir for about 15-20 seconds to chill the bourbon mixture. You'll notice the outside of the copper mug will start to turn frosty.
Top with ginger beer. Gently stir to combine. For the most refreshing drink, make sure to chill your ginger beer first.
Place the mint sprig in the palm of one hand and quickly clap over it to release its fragrance. Add the sprig to the mug with the lime. Enjoy!
