Chalone Wine Group has built its philosophy around the concept of terroir, a French term used to define the myriad of indescribable geographic and climatic conditions that make each growing region and vineyard site unique. By developing or acquiring vineyards in distinctly different locales, Chalone Wine Group assures that each wine estate produces wines that reflect its unique location. As the company grows, it will continue to focus on quality and terroir. By directing all aspects of winemaking and winegrowing to ensure the highest quality, Chalone Wine Group limits each winery to a production level that is in keeping with our standard of quality as well as our dedication to the vineyards within its appellation. The company as a whole continues to grow by adding first-class wine estates in distinctive grape growing regions.Chalone Wine Group owned and operated Acacia Winery, Provenance Vineyards, Hewitt Vineyard, and Jade Mountain in Napa County; Chalone Vineyard in Monterey County; Moon Mountain Vineyard, Dynamite Vineyards, and Orogeny Vineyards in Sonoma County; and Echelon Vineyards in San Miguel. In conjunction with Paragon Vineyard Co., Chalone also owned and operated Edna Valley Vineyard in San Luis Obispo County. In Washington State, the company owned Sagelands Vineyard and Canoe Ridge Vineyard.
