They are located in Mendocino County, 100 miles north of San Francisco. Their organic vineyards have been certified since 1986, so synthetic pesticides and chemical fertilizers are not used. Every day is Earth Day in Yorkville!
The vineyards are 1,000 feet or more above sea level, where sun-filled days and cool nights, tempered by coastal fogs, combine to consistently produce premium quality grapes. Only here you will find the only known winery to grow and produce all eight of the main Bordeaux grapes each as a varietal wine: Sauvignon Blanc, Semillon, Malbec, Cabernet Franc, Petit Verdot, Merlot, Cabernet Sauvignon and Carmenere.
