Exploring New Territory

Having established a name for itself as a producer of highly regarded Burgundian and Rhône varietals grown in Santa Barbara County, the second-generation sought to expand upon Fess’s vision. Leveraging long-term relationships with committed Napa growers, Addendum was born. A limited, stand-alone offering of Bordeaux varietal wines, Addendum sources fruit from some of the most prestigious and established vineyard holdings in the Napa Valley.
