2011 Constant Diamond Mountain Vineyards Merlot Napa

Diamond Mountain vineyards receive plenty of sunshine at these elevations and are typically above the coastal fog line. But given its western proximity, the area still easily cools down from early morning and late afternoon Pacific Ocean breezes. The AVA (American Viticultural Area) covers 5,000 acres but just over 500 acres are under vine. Diamond Mountain soils, mainly weathered, red sedimentary rock and decomposed, volcanic ash, are infertile, quick-draining and produce small, thick-skinned grapes, bursting with chewy tannins.
