Grape Sparklers

• MAKE-AHEAD

Ingredients

1. 4 pounds red grapes, stemmed
2. One 750-milliliter bottle dry sparkling wine, such as Prosecco, chilled
3. 8 mint sprigs

1. Thinly slice 1 cup of the grapes and refrigerate. In a food processor, coarsely chop the remaining grapes in batches. Transfer the chopped grapes to a saucepan and bring to a simmer. Cook until the grapes have released most of their juice, 5 minutes.
2. Working in batches, strain the grape juice into a bowl, pressing hard on the solids. You should have about 3 1/2 cups of juice; refrigerate until cold.
3. Divide the sliced grapes equally among 8 Champagne flutes. Pour the chilled fresh grape juice into the flutes and top with the sparkling wine. Garnish each drink with a mint sprig and serve right away.
