Add all ingredients, except for the alcohol, to a large stock pot and bring to a boil. Stir until sugar has dissolved. Turn off heat and let cool to room temperature. Once the mixture has cooled, stir in the alcohol. Pour into clean mason jars and add in 1-2 cinnamon sticks per jar. I add two into quart size mason jars. Seal and place in the fridge or cool, dark room.

It's best to let it set for about two weeks.
