The Plaisentif is the "cheese of violets."
It is only exclusively produced in Piedmont in Val Chisone and Val Susa. It seems that the origin goes back to the end of '500 when it was produced in Piedmont with raw cow's milk. Its name derives from the fact that the pastures of the Val di Susa and Val Chisone occurred during the period of flowering violets (June and July).
The maturing of this cheese from Piedmont is 80 days and may be marketed only to the third Sunday of September, when the feast of "Poggio Odo" in Perosa Argentina. The Plaisentif is branded with a stylized purple.
