About Tosti

Tosti1820 produces wines and sparkling wines since 1820: more than 200 years of grape harvests in the name of quality for a family business run by the Bosca family for 8 generations. A heritage made up of years of tradition and culture in winemaking that led to identifying the best areas of cultivation and the best methods of processing grapes. This long experience allows Tosti1820 to produce quality bubbles with a strong identity.

For Tosti1820, the passion for wine is a family business. Today Giovanni Bosca, together with Mariacristina Castelletta, are the seventh generation at the helm of Tosti, while his sons Giulio and Guglielmo Bosca represent the eighth generation.
