In a large saucepan, combine the cider, juice and candies. Place the allspice on a double thickness of cheesecloth; bring up corners of cloth and tie with string to form a bag. Add to pan. Bring to a boil. Reduce heat; cover and simmer until flavors are blended, 5 minutes.
Discard spice bag; stir in honey. Transfer to a 3-qt. slow cooker; keep warm over low heat.
