Add cranberry juice, bourbon, maple syrup, orange juice, and orange bitters to a large pitcher
Stir well until the maple syrup is fully incorporated.
Cover and refrigerate until ready to serve. Do not add ice to the pitcher as it will water the drink down, put ice in each individual glass.
Fill glasses with ice and pour cocktail over ice.
Garnish with rosemary, orange slices, or fresh cranberries, if desired.
Notes
*If storing in the fridge overnight, keep the garnishes out of the pitcher until just before serving or added to each individual drink, since the rosemary and/or orange slices can make it bitter the longer it sits in the drink.
