1 tsp of grenadine syrup
6 oz of grape juice
1 oz of Vodka
1 splash of 7-up soda (or Sprite)
1 1/2 oz of blueberry schnapps
Shake all ingredients except the 7-Up and pour over ice into the glass. Add a splash of 7-up and stir carefully: don't kill the carbonation.\r
Add the vodka if you wish to make the drink a little stronger, but you'll never taste the difference either way.
