                                According to European Union spirits legislation, any product labeled as a liqueur must contain at least 100 grams of sugar per liter. As Curacao is a liqueur, this means it absolutely contains sugar, although the precise amount can vary significantly by brand and whether it is a liqueur or a non-alcoholic syrup.
