Castel San Mauro is located on the Italian north-eastern hills embracing Gorizia, known as Collio. It extends over an area of 25 hectares of which 6.5 are with vines. The south-facing land, among the woods of Mount Sabotino and the meadows that slope down towards the Isonzo River, its type consisting of marl and sandstone (Ponca), are conditions that have favoured the cultivation of the vine since ancient times. From the mid Twentieth Century the farm belongs to the family of the current owner, Manuele Mauri. In 1958, Manuele's Grandfather Gilberto began renovating the old villa and the old vineyards. Since taking over Manuele has moved to organic and biodynamic farming practises, all to limit intervention. The 60 year old vines are also providing the stock for the selection of new plants.
Using raw material from nearby Aurisina on the coast, Manuele has developed the world's first marble tank fermentation system. Marble is hygienic, breathable, inert and imperceptible with respect to the liquid contained within in it, protecting the vinification and ripening of wine from bacterial contamination, intrusion of wood components and roasting of stalks. The tank walls are modular allowing each container volume to be altered in respect of its contents and dismantled for
