In a saucepan combine the brown sugar, cloves, cinnamon stick, nutmeg, orange zest, cardamon seeds and add a cup of water.
Bring to a simmer, stirring until the sugar has dissolved. Remove from the heat and allow to infuse for 20 minutes. Strain out the solids.
To make the latte, add 2 tbsp of syrup to each mug, add a cup of coffee to each and finish off with the hot frothed milk.
