Oster Wine Cellars is a small family winery established by Ken Oster, Teresa Fetzer Oster and their children. They specialize in estate-grown Cabernet Sauvignon, produced from their certified organic vineyards, located in Mendocino County’s Redwood Valley. Their small production allows them to remain hands-on in every aspect of vineyard management and winemaking practices. They are dedicated to creating wine that expresses the unique characteristics of our Redwood Valley appellation. They invite you to join our wine club where you may enjoy the convenience of receiving a shipment of our wines once a year upon release.
