On February 6th, 1930, Daniele Venica signed a preliminary purchase agreement for a farmhouse in Cerò, a location within the municipality of Dolegna del Collio, thus becoming the progenitor of the Venica family and the founder of the namesake estate. At that time, the central part of the estate consisted of approximately 10 hectares, including a rural house, a barn, vineyards, fruit trees, and surrounding arable land. Therefore, the Sauvignon "Ronco del Cerò" is a particularly significant wine for the winemakers of Dolegna, as it evokes the origins of the winery and is historically connected to four generations of the family.
