Spring Mountain Climate & Viticulture
The Impact of Spring Mountain Climate of Cabernet Sauvignon Production
Spring Mountain experiences cooler days and warmer nights than much of the broader Napa Valley AVA. Because of its higher elevation, the region often escapes the foggy, cool mornings that are typical on the valley floor.
Cool air enters the region from Sonoma County because the Spring Mountain AVA sits a lower between the taller Bald and Diamond Mountains. Moderate temperatures allow for a long growing season for Napa Valley standards.
These climatic characteristics cause the typical Spring Mountain Cabernet Sauvignon to have soft tannins, relatively low acidity and strong fruit flavors. Red varietals comprise over 80% of vineyard production. The AVA receives quite a bit of precipitation and is extremely lush and scenic. York Creek is the main watershed in the area.
