Oak Knoll District celebrates 10-year anniversary

May 01, 2014

The recognition of an AVA is based largely on its uniqueness of soils and geology, geography, climate and, to a lesser degree, its historical significance. The OKD is one of the oldest grape-growing areas in Napa Valley beginning with Capt. JW Osborne's purchase of land 3 miles south of Yountville, which he named Oak Knoll around 1850.
