Frangelico is a hazelnut liqueur that originates from Italy and is known for its distinct nutty flavor, which is enhanced by hints of vanilla and chocolate. This liqueur is made from Tonda Gentile hazelnuts, which are toasted and then distilled into a rich, aromatic spirit. The addition of cocoa, coffee, and vanilla extracts contributes to its complex and inviting taste profile. It is often recognized by its unique bottle shape, which resembles a friar's robe, complete with a rope belt.

In the context of cocktails, Frangelico offers a versatile ingredient that can add depth and sweetness to a variety of drinks. It pairs exceptionally well with coffee-based cocktails, enhancing the flavor with its nutty undertones. Additionally, it can be used in dessert cocktails, such as the Nutty Martini or the Hazelnut Espresso Martini, where its creamy texture and rich flavor complement the other ingredients. Frangelico can also be enjoyed on its own, served over ice or as a digestif, making it a flexible addition to any bar collection.
