Pour the ginger ale and vodka into a blender. Add peaches and ice. Cover and blend until mixture is smooth and no chunks remain. If mixture is too thick or difficult to blend, add an additional ¼ cup of ginger ale.
Pour into highball glasses and serve immediately.
If peaches are frozen out of season, they may not be sweet enough on their own. As needed, add a splash of simple syrup to mixture while blending.
Vodka can be substituted with rum.
Ginger ale can be substituted with ginger beer.
To make non-alcoholic - replace rum with additional ginger ale.
