7 Blocks of Cabernet Sauvignon
Winfield Vineyard consists of seven distinct blocks of Cabernet Sauvignon on a 12-acre “mezzanine” above the valley floor. Each block is differentiated by its soil type & moisture content, rootstock & clone selection, viticultural protocol and irrigation program.
The vineyard is located in the Calistoga Sub-appellation of the upper Napa Valley where the volcanic slopes of Mount Saint Helena rise out of the Valley’s alluvial floor. The confluence of geologic landscapes at this site, combined with the unique mesoclimate of the upper valley, create a terroir ideal for Cabernet Sauvignon. Winfield Vineyard is perched on a sloping mezzanine, or bench, above the Valley floor, which provides a geological advantage with respect to the underlying granular, friable and well-aerated volcanic soils and is surrounded by a natural amphitheatre of steep, sun-focused hillsides. The soils are predominantly cobbley loam with gravelly loam in the upper sections. 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.
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. This up valley mesoclimate accentuates these temperature rhythms because daytime temperatures are higher at our altitude and nighttime conditions are influenced by the maritime air pulled into the valley in the hot afternoons and by the cooler air flowing down the grade from Mount Saint Helena. These swings are unique to our location throughout the growing season making the periods of fruit ripening much cooler than widely believed.
“I’d be hard pressed to find a site that’s better than y’all’s site, top to bottom.”
