Founded in 1972 by former publishing executive John Shafer in Napa Valley’s Stags Leap District, Shafer Vineyards is a pioneering estate celebrated for opulent, age-worthy wines and early leadership in sustainable farming. Alongside his son Doug and longtime winemaker Elias Fernandez—who earned Food & Wine's Winemaker of the Year honor in 2002—Shafer established the benchmark for plush, velvety Stags Leap Cabernet Sauvignon.

The 2002 Napa Valley Cabernet Sauvignon, which later evolved into the estate's "One Point Five" bottling, is sourced primarily from Shafer’s rocky, volcanic hillside estate vineyards and the neighboring Borderline Vineyard in the Stags Leap District, supplemented by select Napa Valley sites. Combining fruit from steep, shallow-soiled hillside blocks with warmer valley-floor parcels gives the wine its signature balance of concentrated dark berry intensity and supple structure.
