Jamieson Ranch Vineyards founded the Light Horse Foundation. The foundation is committed to people with disabilities, especially those with autism, and supporting other major humanitarian disabilities. A portion of the profits from Jamieson Ranch Vineyards supports the Light Horse Foundation. Jamieson Ranch Vineyards (founded in 2013) is Napa Vally's southernmost winery, one of the world's major wine regions. The 300 acres of the estate are perched on gently rolling hills, and on the terraced vineyards, the grapes benefit from the cool morning mist and the breezes of nearby San Pablo Bay, climatic conditions that only benefit the production of exceptional Pinot Noir and Chardonnay.
