Shafer Vineyards traces its beginnings to 1972 when John Shafer left a 23-year career in the publishing industry and, with his family, moved to the Napa Valley to pursue a second career in wine. After purchasing a 210-acre estate in Napa Valley's Stags Leap District, the Shafer family faced the arduous task of replanting the existing vineyards, which dated to the 1920s, and terracing the steep and rocky hillsides, eventually expanding vineyard acreage to its current 50 acres. Evolving from grape growers to vintners, the Shafers crushed their first Cabernet grapes in 1978 and began construction on their winery a year later. From a modest beginning of 1,000 cases in 1978, the winery has grown steadily until reaching its present size of 32,000 cases of Cabernet Sauvignon, Merlot, Chardonnay, Sangiovese and Syrah. Today Shafer wines are available in major markets nationwide and in many foreign markets.
