The Heritage of Schrader Cellars Over the course of more than two decades, Schrader Cellars has burnished a reputation for excellence by imposing the highest standards of winemaking and sourcing in pursuit of producing Cabernet Sauvignon that captures the essence of the best vineyards in Napa Valley. Schrader Cellars was founded in 1998 by Fred Schrader, who set out to craft Cabernet Sauvignon with a single-minded focus on quality and provenance. Thomas Rivers Brown joined Schrader Cellars as winemaker in 2000.
