Not sure how duckbagg does it. But far as the wine. I have a rotersie I will use.. So ill use 1/4 drippings 3/4 wine. and Inject it into the meat every 30min, About 1/4 cup per injection. that way the wine will cook from inside out. I also will most likely put the onion's, and garlic inside the duck with the sausage and cabbage. I will more than likely add some of my own spices to it, such a Rosemary and maybe throw some lemon slice inside there too. I perhaps may even make a Sweet Orange sauce to add to it. I will serve with fresh fruit most likely, things of that sort.
If you wanted to go different way, you could serve on a Dirty rice base, served with "Red Hot Potato's" Some good rolls with a honey butter and another item of choice. as far as beverages, THe red wine yo cooked with maybe great, depending on which one you get, or just some good southern sweet tea.
This is just my take on the matter.
