In 1989, Mary Miner Oakville Ranch encompasses 350 acres and is planted with an 80 acre vineyard. Located in the eastern hills of Napa Valley, the vines are comprised of Cabernet Sauvignon, Merlot, Cabernet Franc, and Chardonnay.
The estate vineyard is planted in shallow, volcanic soils that are red from oxidation. They are very unfertile and produce mountain grapes with concentrated flavors and aromas. Because the land is 1,400 feet above sea level, fog is less of an issue on summer mornings than it is on the Napa Valley floor.
Vineyard management practices are meticulous at Oakville Ranch. Vines are rigorously pruned to maximize sun exposure. Only a few bunches are allowed to grow on each vine, and yields are closely controlled.
Ashley Heisey is the winemaker at Oakville Ranch. Her current vintages include the 2005 Chardonnay, 2003 Cabernet Sauvignon, 2004 Field Blend, 2002 Robert’s Blend (mainly Cab Franc), and the 2000 Reserve Cabernet Sauvignon (Cab and Cab Franc).
