Combine grated red apples, apple cider vinegar, brown and white sugar, chai tea leaves (removed from bag), and cinnamon sticks in a jar. Give the mixture a few stirs and then screw the top on tight before storing it in the refrigerator for 2-3 days to create the Apple Chai Shrub.

After 2-3 days, strain the shrub and remove the cinnamon sticks and chai tea leaves.

Combine 2 ounces of Bourbon with 1 ounce of the chilled Apple Chai Shrub over ice in a cocktail shaker; shake and then strain into two glasses. Top each glass with Prosecco and garnish with an orange peel and cinnamon sticks.
