First planted by Swiss-Italian immigrants in 1872, this vineyard faces west on the side of Howell Mountain with an elevation ranging from 800 feet to 1000 feet above sea level. Sorenson Vineyard has a slope averaging 27%, one of the steepest in Napa. The soils are comprised of “Konocti Series Volcanics” a very densely compacted volcanic ash with large granitic boulders throughout. The vineyard sits vertiginously in the frost-free zone above St Helena overlooking the Bell Canyon Reservoir. While the Sorenson Vineyard is located on Howell Mountain, the Howell Mountain AVA requires a minimum elevation of 1,400 feet above sea level.
Purchased in 1987, developed by our founder Tom Burgess, owned by son James Burgess since 2012, the Haymaker Vineyard faces east on the opposite side of Howell Mountain. The slope averages 20% and is well drained due to the volcanic ash and marine sediment soils, producing grapes that have a rich, dark core of varietal character. Being above the frost-zone in Napa Valley, allows for a long growing season. Very hot days and cool nights, our unique slope and elevation, provide an intense mountainous core to all our wines.
