Hot wine, or vin chaud, is my favorite winter drink. I always order it whenever I eat out on freezing evenings. But you can make it quite easily too - just drop several pieces of cloves and a cinnamon stick (I only use half of it if it is just for me), some fruit (orange or apple) and wine. I learned that some people drink it with white wine, too.
As much as you want to make it sugar-free, it is a good idea to add at least a spoonful of honey. Also, don't boil it too much!
Voila, a winter specialty. Exactly what I need tonight.
