Vermentino is a world-famous vineyard in Sansretour Valley, Toussaint, set near the tall windmills along the Sansretour River, east of Castel Ravello. It is mentioned already in the saga, where its steward was Malatesta.

In Blood and Wine it belongs to Matilda de Vermentino, the adopted daughter of the family, and the estate is going through hard times. Its rivalry with Coronata is at the center of Wine Wars: Vermentino.
