Select and pre-chill an Old Fashioned glass.

Prepare an orange zest twist for garnish.

Stir the bourbon whiskey, straight rye whiskey, Caribbean blended rum, Cockburn's Tawny Eyes Tawny Port, orange bitters, and Angostura aromatic bitters with ice.

Strain the mixture into the ice-filled Old Fashioned glass, using small or cracked cubes if available.

Express the orange zest twist over the cocktail and float it as a garnish.
