Fiore Sardo and Pecorino Sardo are not the same cheese. Along with Pecorino Romano, they are two of the three sheep's cheeses traditionally made on Italy's second-largest island of Sardinia that carry a Protected Designation of Origin (PDO) certification from the European Union (EU). Fiore Sardo is gamey and smokey, whereas Pecorino Sardo is piquant and sweet.
