Pour the apple cider into a small saucepan and heat over medium until it's steaming and tiny bubbles form at the edge, about 3 to 4 minutes. Don't let it boil hard.
Take the pan off the heat, add the chai tea bag and steep for 4 to 5 minutes. Longer steeping means stronger spice (and more caffeine with black tea chai).
Remove the tea bag, giving it a gentle squeeze, and stir in the maple syrup. Taste and add a little more if you like it sweeter.
Heat the milk in the microwave or a small pan until hot but not boiling, then froth it with a handheld frother, a whisk, or by shaking it in a tightly sealed jar with a towel over the lid (careful, it's hot).
Pour the spiced cider into a mug, then spoon the milk foam on top and pour in the rest of the milk slowly.
Dust with cinnamon, tuck in a cinnamon stick and float a star anise pod on the foam. Sip carefully, it's hot.
