Cabernet Sauvignon undoubtedly dominates Napa Valley today, covering half of the land under vine, commanding the highest prices per ton and earning the most critical acclaim. Cabernet Sauvignon?s structure, acidity, capacity to thrive in multiple environs and ability to express nuances of vintage make it perfect for Napa Valley where incredible soil and geographical diversity are found and the climate is perfect for grape growing. Within the Napa Valley lie many smaller sub-AVAs that express specific characteristics based on situation, slope and soil?as a perfect example,?Rutherford?s famous dust or?Stags Leap District's tart cherry flavors.
