In 1920 Giovanni Macario inherited from his father a few days of vineyard in the Coste del Sole region in Castel Boglione. In the following years he decided to expand the business by purchasing other lands and thus giving life to his own winery.

Production at the time was around 5 days of vineyard and was mainly focused on the traditional qualities of Monferrato: Barbera, Freisa and Moscato.

81 years later that company takes the name of the founder's granddaughter and current owner Giovanna Macario.
