William Cole Vineyards was founded in 2002 in St. Helena, in Napa Valley. Located in one of the area’s original 19th century wineries, William Cole is owned and operated by William and Jane Ballentine. William, a fourth-generation Napa Valley vintner, is also the winemaker. William previously worked for Gallo, his father’s Ballentine Vineyards, and St. Clements Vineyards, all of Napa. Their family enterprise is named after their son, Cole, and one of their cuvees is named after their daughter Claire. So far the small producer makes just one cuvee, a Cabernet Sauvignon.
