Warm & Cozy Mulled Wine is a sweet wine with notes of cinnamon, orange, clove, nutmeg, and berries. It's meant to be served warm and enjoyed on cold days or around a fire. 
Here are some tips for making mulled wine:
Adjust sweetness: Add a bit of sweetness to balance the spice and acidity. Honey is a classic choice, but maple syrup can also add flavor. 
Add citrus: Orange slices are standard, but you can also add lemon for a sweet and tart balance. 
Add a spirit: Brandy or bourbon can add warmth and complexity. 
Add other ingredients: Try cranberries or blackberries for added flavor. 
Garnish: Add cinnamon sticks, fresh citrus or berries, or a star anise pod to your glass. 
Pair with food: Mulled wine pairs well with sweet and savory options like smoked ham or sharp cheeses.
