The grapes come from the estate vineyards in Jameson Canyon and are selected by Napa Valley growers. The estate vineyards are planted on rolling hills at the southern end of Napa Valley. The growing conditions in the Jameson Canyon are very similar to Carneros, the neighboring appellation just west of the Napa River. Winds flow through Jameson Canyon, bringing the cooling influence of the nearby Pacific Ocean and providing a long, cool growing season that enhances and concentrates the intensity of the varietal characteristics. A proportion of grapes are harvested from vineyards in Carneros and the Napa Valley which lend more texture and structure to the blend. The vines are grown sustainably and are certified by Napa Green, Fish Friendly Farming, and the California Sustainable Winegrowing Alliance.
