Place wine, sugars, spices and orange zest in a medium saucepan over medium-high heat. Bring to a boil, stirring to dissolve the sugar, then reduce heat to medium-low and simmer until the mixture has reduced to 1 3/4 cups (10 - 15 minutes), stirring occasionally.

Pour the wine mixture through a strainer into a clean bowl, then pour the syrup back into the saucepan. Discard the solids. Add the cranberries to the syrup, and cook over medium heat until they burst and soften (5 - 6 minutes), stirring occasionally. Transfer to a clean jar, cover and refrigerate until ready to serve. Can be made up to 1 week in advance.
