Tips:
* Use a good quality red wine for gluhwein. A fruity wine, such as a merlot or cabernet sauvignon, will work well.
* Add additional spices to your gluhwein, such as cardamom, nutmeg, or ginger.
* Serve gluhwein with a garnish of orange slices or cinnamon sticks.
* Gluhwein can be made ahead of time and stored in the refrigerator for up to 2 days. Reheat gently over low heat before serving.
