The winemaking activity of the Collalto family, which began in the Middle Ages within the walls of the San Salvatore Castle, has never been interrupted. In 1904, in order to adapt to the new requirements of the oenological science as well as to more modern and practical architectural criteria, Count Ottaviano Antonio Collalto built right in the center of Susegana a specific and airy structure which still houses the winery, offices and some housing, stables, agricultural machinery and farming equipment and was carried out by the young engineer Carpené Malvolti.
More than a hundred years later, the winery maintains its original architecture, whose appearance is characterized by the recognizable corporate colors of the houses of Collalto: yellow ocher walls adorned with the characteristic red burgundy bands. The internal structure of the building, where all the operations for the production of Conte Collalto wines are implemented, has recently undergone a prudent modernization to bring it to the highest standards of wine making, with vinification plants of absolute modernity.
The vineyards of the Collalto Winery currently produce around 850,000 bottles, of which 550,000 of Prosecco.
Conte Collalto works in his wine cellar only grapes of property and follows the entire production chain. In effect, every grape produced in the properties of Isabella Collalto is vinified in the ancient winery of Susegana and comes out exclusively under the Collalto brand, recognized for years for its quality and seriousness.
