To make the cider syrup. In a small pot, bring the apple cider and cinnamon sticks to a boil over high heat. Boil 8-10 minutes, until reduced by half. Let cool.Working on a heat-proof tray, use a kitchen torch to burn 1 cinnamon stick with 2 sage leaves, then place a cocktail glass immediately over the cinnamon and sage, trapping in the smoke. Let sit 2-5 minutes.In a cocktail shaker, muddle the blackberries and sage, squishing the berries to release the juices. Add 1-2 tablespoons of cider syrup, lemon, bitters, and bourbon. Shake to combine. Add ice to the glass. Pour the drink over, and gently stir. Garnish with fresh sage and cinnamon.
