Glogg is essentially a warmed punch made with an infused distilled spirit such as vodka or aquavit as well as fortified wine—that is, wine that's had extra alcohol added. The infusion needs to steep for a week, so factor that into any party plans.
This recipe is lovely and bright. It puts color in your cheeks. Leftovers can be stored in a glass jar in the fridge and reheated. The flavor mellows over time. A must for a cold winter night anywhere.
