When we purchased the 7-acre vineyard on Atlas Peakin the Western Vaca Mountain Range in Napa Valley, we knew that great mountain fruit would come from its volcanic soils.
The vineyard, part of the 45-acre property perched atop Atlas Peak, is one of the highest vineyard sites in Napa Valley, rising 2,100 feet above sea level. The eleven year old Cabernet Sauvignon (clones 7 and 337) and Petit Verdot (clone 400) vines are exposed to a unique microclimate and soil.
Unlike the Napa Valley floor, which is often covered in morning fog, the mountain vineyard is exposed to more sun during the growing season. Refreshing mountain breezes cool hot summer days, protecting the fruit from overheating. The nights are much cooler than other areas and can sometimes experience a 20-degree drop in temperature. These cool nights allow for slower maturation of the fruit, resulting in well-balanced, complex wine.
The shallow volcanic soils limit vine growth, producing small amounts of fruit with exceptional, intense varietal character.
Au Sommet is a partnership between Heidi Peterson Barrett, John Schwartz and Jim Barbour and is a Cabernet Sauvignon and Petit Verdot blend from our seven acre vineyard on top of Atlas Peak in the acclaimed Napa Valley.
