1972- Claude and Anne Berthoud settled in historic Sonoma Valley and purchased the six-acre property now known as Berthoud Winery.
The story of the Berthoud family began in the Old World. Claude Berthoud spent his youth in a small Swiss village outside of Geneva in the 1930s and ’40s where wine played an integral part in village life.

Grapevines etched the hillsides surrounding the village and wine was poured in every home at every meal. Claude’s childhood dream was to farm his own grapes and make his own wine. After many adventures, he ended up in California in 1954. His first winemaking experience came in a San Francisco garage in 1967 with Zinfandel grapes purchased from a vineyard in Dry Creek Valley. He employed Old World winemaking techniques that he observed while growing up in his native Switzerland, such as fermenting grapes in open-top vats and aging the wine in small, oak barrels. The results were positive, inspiring him to fulfill his childhood dream by settling permanently in historic Sonoma Valley. With the help of his son, Michel (Mike), Merlot vines were planted immediately and within a few years, they were making wine from their own grapes.
