Montenero was founded on the slopes of Etna, 750 meters above sea level, by the Bertino family. Initially owners of a medium-sized Nerello Mascalese vineyard, they decided to pursue viticulture: a choice particularly appreciated by their eldest son, who has passionately followed the family business for over a year.

The founder, Bertino Francesco (grandfather of the current heir), purchased the vineyard in 1955 for business purposes. After approximately five years of dedication and constant care, the vineyard began producing, allowing the start of commercialization. The idea proved successful and profitable, but due to limited interest in formalizing the venture, the company was never officially established.
