Additional grapes, orange wedges, and apple wedges, threaded on toothpicks or small wooden skewers(optional)
Combine the red wine, brandy, liqueur, orange juice, and sugar in a large pitcher or container and stir well.
Add the oranges, red and green apples, and grapes. Chill the mixture for several hours at least.
Just before serving, add the sparkling water. If you're not keen on sangria-logged, sodden fruit, strain the sangria, discarding the boozy fruit. To serve, pour the sangria into generously sized red-wine goblets or cocktail glasses filled with ice. Garnish the goblets with skewered fresh fruit, if desired.
