depends on how much you want to make, but you need some dry red wine (preferably for me in this matter and to stay authentic, tempranillo and rioja), brandy, sugar (to taste), some sprite or ginger ale, and some lemons, limes and oranges.....possibly even add some other frozen fruits as well....but the key is to mix up like the night before and refrigerate....that way all the flavors have a chance to marry....
edit note....forgot, add some orange juice as well....
