Hazelnut liqueur is a sweet, nut-flavored spirit made by infusing alcohol with roasted hazelnuts, sugar, and sometimes spices like vanilla or cocoa. This liqueur is known for its rich, warm hazelnut flavor and smooth, slightly syrupy texture. It’s often enjoyed in dessert cocktails, coffee drinks, or even sipped neat or over ice. Hazelnut liqueur is perfect for adding a nutty, sweet complexity to a variety of cocktails, especially those with cream, coffee, or chocolate. The most popular hazelnut liqueur is Frangelico, known for its iconic bottle shaped like a friar and its smooth, balanced flavor.
