To make spiced simple syrup, combine sugar and water in a medium saucepan and cook over medium heat just until sugar dissolves. Turn off heat and add ginger, cinnamon and star anise. Let infuse 1 hour then strain into a jar.
Combine wine, orange juice, brandy, sliced orange, seeds of the pomegranate and spiced simple syrup in a large pitcher and stir well. Refrigerate overnight (or at least 4 hours, but really, overnight is much better) before serving.
