About
Promontory is a Harlan family winery on Oakville’s southwestern ridge, set within a secluded canyon shaped by two fault lines. Its terrain includes volcanic, sedimentary, and metamorphic soils across 500 feet of elevation. Less than ten percent of the property is planted to vine, with forest, woodlands, and rugged slopes defining the landscape.
