In a medium saucepan with a tight-fitting lid, place cranberries, sugar, orange zest, orange juice and cinnamon. Stir. Bring to a boil, then reduce the heat to medium-low, cover and simmer, stirring every 10 minutes, until it reaches your desired consistency (about 35-35 minutes).

Take pan off heat and stir in bourbon. Refrigerate until well chilled.
