Tournesol Vineyards and Wine Estate is located in the Coombsville AVA of Napa Valley. In 1999, proprietors Bob and Anne Arns planted 15 acres of Bordeaux varietals on a gently sloping bench 300 feet above the valley floor. Tournesol vineyard practices follow principles of sustainability and organic farming, and the property is certified Napa Green. The Arns are dedicated to producing the finest estate grown Cabernet Sauvignon and Bordeaux style blends, while being responsible stewards of the land.
