The vineyard blocks, totaling 41 acres, are laid out in three isolated pockets ranging from approximately 500 to 1,000 feet in elevation. They include the two Schram sections, Napa Valley’s first hillside vineyards, originally established in 1862 by Jacob Schram. The third piece is the adjacent McEachran parcel that was first planted by Colin McEachran in 1878 and then purchased by Schramsberg in 1985. These are the southernmost vineyards in the Diamond Mountain District AVA. Flanked by two cool creek canyons (Nash Creek to the north and Ritchie Creek to the south) and surrounded by dense coniferous and deciduous forests, the vines here produce late-ripening, richly concentrated fruit with average yields of just two tons per acre.
