Put all of the ingredients in a small pan and warm over a medium-low heat, stirring occasionally. Warm until it is steaming and reduce the heat - you ideally want to warm it at least 10 minutes, but nearer 20 is better, so the flavors infuse and sugar dissolves. Don't let it boil.
Remove the spices and orange rind from the pan and serve warm, topped with orange slices if you like, adding a little more sugar or honey to taste.
Note - you can use a bit more wine/juice with the same level of spice. If you want to warm a whole bottle, triple the wine, sugar, orange juice and water but probably just double the spices.
