In a small saucepan over high heat, combine the sugar with 1/2 cup water and simmer until all the sugar has dissolved, about 3 minutes. Remove from the heat and let cool completely.
In a large pitcher, combine the wine, pineapple juice, brandy, lime, peach, plum and 1/2 cup of the simple sugar syrup. (Reserve the remaining syrup for another use.) Stir well. Chill for at least 12 hours.
