The Fiore Sardo is a cheese of very ancient origins, dating back to the pre Roman Era. At the end of 1700 father Francesco Gemelli wrote about the 'pecorino Fiore Sardo', describing its production and marketing. In 1800 in fact the Fiore Sardo was the only cheese to be exported from the island of Sardegna, and was much appreciated especially by Neapolitan merchants, those from Livorno and the Genovese; the latter used it already in the preparation of the typical sauce, the pesto. Probably the name of this cheese derives from the fact that, until not long ago, wooden forms in the shape of a flower were used in the production phase, leaving the cheese in the form of a flower.

Each Fiore Sardo Dop cheese is univocally identified by a small disc of green casein on which is indicated the sequential number of the cheeses. On the cheese's flat face is also applied a label divided into 16 portions bearing the script "Formaggio Fiore Sardo" and "Indicazione d'Origine Protetta", the distinctive community seal for the Dop's and the protection consortium mark.
