In the early 1970s, Michel and Louis Bronzo acquired the property of Bastide Blanche in Sainte-Anne du Castellet in the Bandol appellation. Their goal was to produce wines equal to those of more famous appellations like Châteauneuf. Their painstaking efforts were rewarded in 1993 when conditions created this benchmark year that put Bandol in general - and Bastide Blanche in particular - amongst the constellation of top producers in France.

Bastide Blanche has been certified Biodynamic since 2020. As is required of Bandol producers, all grapes are harvested by hand. This practice makes it possible to finely sort the bunches during harvest and to protect the fruit until it reaches the cellar.
