Step 1

Press stem (pointed) end of 10 cloves into each tangerine, piercing through the skin. Place tangerines, wine, cider, Lady apples (if using), 2 cinnamon sticks, and cardamom pods in a large pot. Bring to a bare simmer over medium-low heat; cook gently for 20 minutes. DO AHEAD: Mulled wine can be made 2 hours ahead. Cover and let stand at room temperature. Rewarm gently over medium-low heat before continuing.

Step 2

Stir in Port. Divide among glasses; garnish each with a cinnamon stick and a Lady apple, if desired.
