Yorkville Cellars is a small, family-run winery founded by proprietors, Deborah and Edward Wallo. It is located 100 miles north of the Golden Gate Bridge in the Yorkville Highlands Appellation (AVA), which was established in 1998. It rests in Mendocino County adjacent to the Anderson Valley (much cooler) to the northwest and the Alexander Valley (slightly hotter) to the southeast. Yorkville Cellars is the only known winery that grows all eight of the main Bordeaux grapes and then bottles each individually as a varietal each vintage: Sauvignon Blanc, Semillon, Cabernet Sauvignon, Merlot, Cabernet Franc, Carmenere, Malbec, and Petit Verdot. (Probably the one place on earth where one can taste these side-by-side where the grapes were all grown with the same viticultural practices within the same terroir.) All wines produced are vineyard designated. Yorkville Vineyards have been certified organic since 1986 and does not use pesticides, herbicides or chemical fertilizers.
