Measure 2 ounces of Sprite and pour it into your glass. Set it aside. Then, in a shaker, add the mix of 2 ounces of Barton's Sour Apple Vodka with 2 ounces of PURE Cranberry Juice (Ocean Spray brand works great). Shake in ice until cold. Finally, strain the sour apple vodka/cranberry juice mix into the glass containing the Sprite. Enjoy!
