Oster Wine Cellars
All of our fruit comes from our Estate Vineyards located in Mendocino County's Redwood Valley. These vineyards have been farmed organically in accordance with California Certified Organic Farmers (CCOF) since 1992. Organic farming does not allow the use of synthetic fertilizers, pesticides, fungicides and herbicides, which can adversely affect the environment. We feel that it is important to maintain a good relationship with the Mendocino County environment that provides us with the unique opportunity to grow wine.
