In a glass, muddle the cherries with the lime juice.
Stir in the sparkling water.
Fill a copper mug with ice.
Pour the cherry mixture into the mug, then top off with ginger beer.
Notes
I recommend making your ginger beer at home as few store-bought brands are AIP compliant. Here is my ginger beer recipe. A great alternative is ginger kombucha.
