Irish Old Fashioned Recipe

The Irish Old Fashioned transforms the traditional Old Fashioned with a touch of Irish charm, substituting the standard bourbon or rye with smooth Irish whiskey. The addition of Bénédictine liqueur introduces a layer of herbaceous sweetness, blending harmoniously with the warmth of the whiskey. Aromatic Angostura and orange bitters balance the drink, providing a complex yet subtle spiciness that complements the whiskey’s smoothness. Finished with an orange twist, this cocktail is not just a drink but a celebration of Irish spirit, perfect for any occasion where a touch of elegance is desired. Simple, sophisticated, and brimming with character.

What distinguishes an Irish Old Fashioned from a regular one?

The primary difference lies in the base spirit and the addition of Bénédictine. A traditional Old Fashioned typically uses bourbon or rye whiskey, offering a sweet, spicy, and robust flavor profile. In contrast, an Irish Old Fashioned uses Irish whiskey, known for its smooth, mellow, and slightly sweet characteristics, providing a lighter, more approachable base. Bénédictine, a French herbal liqueur, adds a unique, sweet, and herbal complexity that complements the Irish whiskey beautifully, setting this version apart with its distinctive, sophisticated layers of flavor. The use of both Angostura and orange bitters retains the classic’s aromatic depth while introducing a citrusy brightness, enhancing the overall experience and bridging the old with the new.
