Over a century ago, in 1890, the Senator of the Kingdom of Italy Pompeo Molmenti, worked to deepen the knowledge of the territory and its viticulture using the collaboration of French agronomists. He assessed the characteristics of the land, the climate and the Groppello, the native vine. On the basis of the research made, he sensed that rosé, better than other types of wine, could express the characteristics of this land. He then codified, first in Italy, the production process of rosé, calling it Chiaretto. In 1967, the area was recognized for the first time the Denomination of Controlled Origin.
