If you're throwing a big holiday party and your stove is full, use a slow cooker to simmer up this tangy mulled wine. Set up the slow-cooker in the kitchen or on a dining table, and let guests serve themselves.
Stir all ingredients together in a 4- to 6-qt. slow-cooker; cover. Cook until very hot, about 1 hour on high or 2 hours on low; once hot, keep warm on low heat up to 4 hours.
