Diamond Mountain
On the western edge of Calistoga stands Diamond Mountain, one of the least planted mountain AVAs in all of Napa Valley. Extending from 400 to 2,200 feet in elevation and with little insulation from the nearby Pacific Ocean, the few vineyards planted here are blanketed with a dense layer of fog overnight. Moderate temperatures combined with fine volcanic soil lend themselves to vines with low yields, which in turn makes these wines rare. Historically, Diamond Mountain wines combine a backbone of mountain fruit with a plush elegance, making them truly distinctive.
