In a pitcher, combine 1 peach, 1 nectarine, and 3 apricots, all pitted and cut into wedges. Stir in 5 ounces peach brandy; let sit at least 1 hour. Stir in 1 750-ml bottle chilled Prosecco (Italian sparkling wine) and 1 cup peach nectar. Add superfine sugar, if desired. Serve chilled.
Makes about 2 quarts.
