The Soils

The vineyard is located in the northern Calistoga District of the upper Napa Valley where the lower volcanic slopes of Mount Saint Helena rise out of the Valley’s alluvial floor.  This confluence of geologic landscapes, combined with the unique micro-climate of the upper valley, create a terroir ideal for growing Cabernet Sauvignon at our spot.

Winfield Vineyard is perched on a sloping mezzanine, or bench, above the Valley floor, which provides an advantage with respect to water quality, drainage and soils, and is surrounded by a natural amphitheatre of steep, south-facing hillsides.  The vineyard’s well taps into an aquifer of pure water weeping off Mount Saint Helena.  Farming this special site is an act of respect for the land utilizing sustainable farming practices.

The Climate

Napa Valley is an ideal grape-growing corridor characterized by its long growing season and its warm, dry days alternating with cool nights frequently marked by layers of fog.  

Our up-Valley location accentuates these temperature rhythms because daytime temperatures are higher at our altitude and nighttime conditions are influenced by cooler air flowing down the grade from Mount Saint Helena. These swings are unique to our location throughout the growing season.
