Night Tripper

Select and pre-chill an Old Fashioned glass.

Prepare an orange zest twist for garnish.

Stir the bourbon, both types of amaro, Liquore Strega, and bitters with ice.

Strain the mixture into the pre-chilled glass filled with ice, ideally using a large cube or chunk of block ice.

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