This white varietal has been traditionally associated with the Northern Rhone, where it is blended with Marsanne to make white Hermitage wines. In 1998, three acres of Roussanne were planted on the southern end of the Truchard Estate Vineyard. Growing in soils composed of volcanic rock and ash, the vines benefit from the gently sloped terrain and cooler Carneros temperatures. Roussanne is a challenging grape in both the vineyard and winery. However, when done correctly it can produce an aromatic and delicate wine with the structure and finesse to age.
