2 bottles dry white wine, chilled (recommended: Pino Grigio)
1 cup white grape juice, chilled
1/2 cup vodka
Place 3 cups grapes in a freezer about 2 hours before you want to serve your sangria.
Combine the chopped apples, lemon slices, grapes halves, wine, sugar, white grape juice, and vodka, in a large glass pitcher filled with ice. Stir well to dissolve the sugar. Add frozen green grapes to glasses and fill with sangria.
