Oakville Ranch is the original mountain vineyard of the sub-appellation that produces the New World's most celebrated Cabernets. Covering just two square miles at the heart of Napa Valley, the Oakville district may be small, but its wines play a very big role in the connoisseur's collection. At 1,400 feet above the valley floor, the Oakville Ranch vineyards produce fruit that speaks from the appellation's signature red volcanic soil with a mountain accent. In the two decades since Bob and Mary Miner purchased the 350-acre ranch, plantings have slowly increased from an initial 55 acres to today's 75 acres of predominantly Bordeaux varietals. It's definitely a trek up the mountain, but well worth it. Kristin led our tasting in the greenhouse--the grounds are amazing and the wines are especially good (Cab Franc). They are only open by appt. M - F, but it you will be on the Silverado Trail on a weekday call and make an appt.
