Pour all the juices in to a large pot, and add the mulling spices wrapped in cheesecloth.
Bring liquid to a boil, then reduce to a simmer for at least 20 minutes, and up to 45 minutes.
At this point, it is optional to add brown sugar if you want to sweeten it a little. Add in up to 3 tablespoons of brown sugar, one tablespoon at a time until desired level of sweetness is achieved.
Enjoy the delicious spicy scent as you sip away...
Notes
The longer you simmer, the more concentrated the flavors become. At 45 minutes, the punch was deliciously spiced, but any longer and the juices will become too thick and syrupy.
