Fernet is the most famous and unavoidable cocktail in Cordoba. A dark liqueur with a bitter, black licorice flavor, it was invented in Italy in 1845 as a stomach medicine. While no longer touted for its medicinal properties, people swear it’s a hangover cure. Córdoba gave birth to a famous cocktail by mixing fernet with Coke, usually named “Fernando.” The general recipe calls for 30 percent fernet and 70 percent Coke, but there are many variations. Other recipes add grapefruit juice or lemon soda. At least 30 percent of the fernet production in Argentina is consumed in Córdoba. Every bar in the province has fernet on its menu, but there are a few, like El Club del Fernet, where you can buy a bottle and then, before going home, label your bottle and reserve the leftover for your next visit.
