In a plastic bag, add the cinnamon sticks, star anise, black peppercorns, cloves, and cardamom pods. Lightly crush and pour into a medium saucepan.
Add the ginger, water and the seeds of the vanilla bean and the scraped vanilla pod to the saucepan.
Bring to a boil over medium high heat. When the mixture is boiling, reduce to a simmer.
Simmer for 10 minutes or so, partially covered.
Remove the pan from the heat and add the tea bags. Let steep for 5 to 7 minutes.
Remove the tea bags from the mixture.
Add the sugar and the milk, whisking thoroughly over high heat until the mixture is brought to a simmer (DO NOT BOIL).
Pour into mugs and add the bourbon.
Stir with a cinnamon stick, garnish with some whipped cream and a bit of freshly grated nutmeg. Enjoy!
