Ingredients

　　2 limes, sliced thin

　　2 small carambolas (star fruit, available at specialty produce markets), sliced thin crosswise

　　1 chilled 750-ml. bottle dry white wine

　　1 chilled 12-ounce can mango nectar

　　1 mango, cut into 1/2-inch cubes

　　1 chilled 12-ounce can ginger ale

　　1 chilled 750-ml. bottle champagne

　　Reserve some of the lime and carambola slices for garnish. In a large pitcher stir together the white wine, the mango nectar, the mango, and the remaining lime and carambola slices. The sangría may be prepared up to this point 1 day in advance and kept covered and chilled. Just before serving, stir in the ginger ale, the champagne, and ice cubes and serve the sangría garnished with the reserved lime and carambola slices.
