About Us / Armstrong Ranch History: Our Cabernet Sauvignon grapes are grown at an elevation of 1,150 feet on Diamond Mountain in Northern Napa Valley. The 13 acres is comprised of well-drained organic soil. Our very steep terraces have five distinct exposures and microclimates, producing grapes that are intensely flavored and rich in complexity. The grapes are hand-picked and sorted in the vineyard. They are de-stemmed, crushed and pumped into a small open–top fermentor. A 50 degree cold soak precedes native wild yeast fermentation.
