The vineyard sources for Roth Cabernet Sauvignon are located in the eastern hills of southern Alexander Valley, at the confluence of the Chalk Hill and Knights Valley appellations. This southern “sub-appellation” is emerging as a leading location for producing Cabernet Sauvignon. Most sought after are the region’s hillsides and mountain locations, where diverse, nutrient-deficient soil types and microclimates are proving ideal for developing concentrated varietal character.
