Port Old-Fashioned

Chill an Old Fashioned glass in advance to ensure optimal serving temperature.

Prepare an orange zest twist for garnish and set aside.

Stir the bourbon whiskey, Cockburn's Tawny Eyes Tawny Port, maple syrup, and Bob's Abbotts bitters with ice until well chilled.

Strain the mixture into the pre-chilled Old Fashioned glass filled with fresh ice.

Express the orange zest twist over the cocktail to release its oils, then use it as a garnish.
