Created in 1978 by Baron Philippe de Rothschild and Robert Mondavi, Opus One remains committed to realizing our founders’ dream of bringing to life one unique wine that expresses the seamlessly blended personality and character of each family.  With a great sense of pride in our work to realize this dream, the people of Opus One bring profound dedication and unsurpassed attention to detail in our daily work.  We care deeply for the quality of our relationships within the winery, with our trade partners, and with our customers.
