Napa Valley Vineyards
The sub-appellations of Napa Valley
North of San Francisco, between the Mayacamas and Vaca Mountain ranges, lays the Napa Valley. Despite being one of the smallest winegrowing regions in the world, Napa Valley abounds with complexities due to its undulating topography ranging from breeze-blown flatlands near sea level and rolling hills at the southern end, to steep hillsides rising up to Mount St. Helena at the northern border. The differences in soil composition throughout the valley and variances in cooling breezes, sun exposure, and daily temperature swings create a great number of distinct microclimates for a region so small.
