O’Shaughnessy Estate Winery is located in a beautiful setting off the beaten path north east of St. Helena in a small town called Angwin. We are on the slopes of Howell Mountain with scenic views of Napa Valley. On your next trip to Napa, please call us to schedule a tour and tasting. When driving to the winery, please be sure to use the directions provided on our website as many online maps are not accurate for our location.
