In 1910, Candide Zufferey bought the land of the Colline de Daval after spending several years in Argentina. The history brought two wineries and two families together after the wedding of Monique and Bertrand Caloz-Evequoz. A new winery has been built at the Colline de Daval and the entire vinification process is centralized there. 

Today the winery Colline de Daval has been family owned for 5 generations. Due to its diversity and its control of the entire production chain, the family company offers a total immersion in the wine universe. The high quality of the local products guarantees a truly unique experience for every single visitor.
