Dutton Ranch is located near the town of Graton in the Russian River area of Sonoma County. The Chardonnay is harvested from a hilltop vineyard above the ranch, about 10 miles inland from the Pacific Ocean, and is rich with volcanic loam. Grapes from this tiny vineyard are shared with DuMol Winery. The Pinot Noir fruit comes from the Thomas Road Vineyards near Sebastopol, an exquisite setting that could be in Tuscany.

Stoney Springs Vineyard is adjacent to the winery where Bob crafts his wines, near St. Helena, in the Napa Valley. The Cabernet Franc grows in a 2 acre section of the rocky hillside vineyard.

Simas Vineyards is in Yolo County, California near Davis about 30 miles east of the Napa Valley. This is a small family - farmed vineyard and supplies the Grenache Noir for the Rose'.
