This aromatized wine hails from Piedmont, where it has been traditionally produced since the 19th century. As its name suggests, full-bodied Barolo wine makes the base of the drink, while the usual additions include a secret and versatile blend of botanicals such as quinine bark—known as china in Italian—gentian, rhubarb, fennel, juniper, citrus peels, cardamom, and star anise.
