Add remaining ingredients to the slow cooker in an even layer.
Heat on Low for 2 hours (or until warmed).
Remove once hot, remove oranges, cinnamon, anise, and cloves and place on keep warm for serving.

Notes
Variations:
If you would like yours to have a bit more of a kick; add a couple of tablespoons of brandy.
Add a cup of fruit, such as strawberries, raspberries, or cranberries, for even more flavor.
I used a red blend, but you could use any red wine you prefer. Remember that if you use a dryer wine, you may need to add more sugar.
You can use a cup of orange juice instead of a sliced orange.
Serving Suggestions:
Serve in clear mugs or glasses with a rim of brown sugar and cinnamon (use an orange to wet the glass before dipping in sugar).
Have garnishes available for your guests (fresh orange slices, cinnamon sticks, and star anise). A spring of rosemary is a cute touch as well.
Serve the mulled wine with a fall treat such biscoff cookies, or slow cooker gingerbread cake.
How to Store and Reheat:Place the leftovers in the fridge for up to two days. Reheat in a pan on the stovetop. OR you can drink this wonderful mulled wine "chilled" the next day.Does the alcohol cook out of this?Yes, if the wine gets too hot, a portion of the alcohol could cook off. To prevent this, after heating up to warm, set the slow cooker to the "warm setting".
