Arrange orange slices on a wire rack. Place on a baking sheet and bake for 3 hours, or until dried.
On a double layer of cheesecloth combine peppercorns, cloves, cardamom pods, allspice, cinnamon sticks, and vanilla bean. Gather up the ends of the cheesecloth, and tie shut.
In a large pan combine orange slices, the spice packet, sugar, orange juice and win. Heat over medium heat to a simmer. Reduce heat to low and cook for 30 minutes.
Remove the spice packet to serve.
