Our Mission Bonded Winery #9 is a portfolio of wineries that expresses the terroir of vineyards in the heart of the Napa Valley. Family Owned: 635 acres, Yountville and Oakville Appellations: 100% Organically Certified: 100 consecutive Harvests.The Company is committed to growing grapes without the use of chemicals. Certified by the California Certified Organic Farmers, Bonded Winery #9 uses organic vineyard management techniques. Selective leaf and shoot removal reduces fungus and mildew pressure. Cover crops like oats, peas, mustard and vetch, are planted between rows to naturally inhibit soil erosion, reduce dust, restore nutrients and encourage microbiological activity. Even grape skins and stems are composted after harvest and added back to the soil, replenishing nitrogen and potassium and increasing microbiological activity.
