In a small saucepan, stir together ingredients for the spiced simple syrup. Bring the mixture to a boil over medium-high heat.
Once the mixture reaches a boil and sugar is dissolved, remove from heat.
Cover and let steep for 15 minutes before straining out the whole spices and ginger. Let simple syrup cool completely before using.
In a large pitcher filled halfway with ice, stir together champagne, mango juice, pineapple juice, pomegranate juice, brandy, spiced simple syrup and fresh cranberries.
Serve with cups filled with additional fresh cranberries and ice. Garnish with slices of candied orange.
