This low sugar version of the refreshing classic grapefruit vodka cocktail, the Greyhound will hit the spot on those summer days when the air AND the sweet drinks are just too heavy.
If desired, wet the rim of a double old fashioned glass and swirl it in Splenda, Stevia, or Salt.
Add ice to the glass.
Pour 1-2 oz. of vodka over the ice.
Fill the remainder of the glass with Grapefruit Sparkling ICE drink or Ruby Red Diet Grapefruit Juice.
Stir well and serve.
You can substitute the vodka with gin if you prefer the original spirit used in the Greyhound!
