On weekends, Nancy, Joe and their three sons planted the vineyard, which is comprised of Syrah, Viognier, Merlot, Cabernet Sauvignon, Cabernet Franc and Sauvignon Blanc.

In 1980 they built the winery on a corner of their 10-acre vineyard property. Later that same year, the first wines bearing the Hart label were produced, bottled and sold. Today, in keeping with the philosophy that small-scale winemaking is an art form engaged in by a winemaker with a passion for wine, Joe Hart, along with his son, Bill, produce about 5000 cases of premium wine annually.

The Hart family places an emphasis on matching grape varieties with terroir. Numerous Gold Medals and Best of Class Awards throughout the years attest to recognition by industry peers as well as by the public to the excellence of Hart Winery wines.
