Smells lovely and, in a slow-cooker, doesn't get in the way of your other holiday preparations.
Two quarts, it turns out, is not an awful lot; if numerous people are sipping (or a few people really like it), have another jug of cider handy and prepare a second bag of spices.
The ingredient list looks like a giant pain, but if you have a fancy store like Central Market in your area that sells loose spices, you can scoop and buy a teaspoon of each for pennies -- I got all of these for a total of about 53 cents. (Nothing else in the store is cheap!)
(From Allrecipes.com, where they offer instructions for brewing in your coffeepot.)
1/2 tsp whole allspice
1 tsp whole cloves
1 cinnamon stick
1/4 tsp salt

Wrap spices in muslin, tie with kitchen twine.
Put apple cider in slow-cooker, stir in brown sugar, add orange wedges and spice bag.
Heat for 20 min, then remove spice bag (this step optional).
