Frangelico Hazelnut Liqueur may taste like a delicious cake or buttery Italian cookie, but this tasty hazelnut spirit is surprisingly gluten-free. Its ingredient list contains Italian hazelnuts, alcohol, water, vanilla extract, coffee extract, cocoa, and some other herbal flavorings (the exact recipe is a secret), but nothing that contains gluten. As such, those with gluten intolerance can confidently enjoy Frangelico Hazelnut Liqueur, whether as an after-dinner digestif or perhaps splashed in their morning coffee. As a rule of thumb, always be sure you choose the actual Frangelico bottle because other hazelnut liqueurs on the market may not be as gluten-safe.
