The value and respect for their lands, inherited from their grandparents and parents, is also transmitted to the three daughters of Ercole and Aurelia: Maria Rita Simona and Martina, all dedicated to a specific role in the company.

The company is located in Lapio, a small town on the hills of green Irpinia, and has about 10 hectares of land of which 6 hectares are cultivated in Fiano, and 1.5 in Aglianico. The territory from the climatic point of view is favored by the presence of the Picentini mountains: one of its peaks, Mount Tuoro (1400 mt.)
