Taoiseach

Select a cocktail coupe and chill it in advance.

Prepare an orange zest twist to use as a garnish.

Stir the Irish whiskey, Cointreau L'Unique triple sec liqueur, Strucchi Rosso Vermouth, Monin Grenadine Syrup, Angostura Aromatic Bitters, and Orange Bitters with ice until well chilled.

Fine strain the mixture into the pre-chilled cocktail coupe.

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