First planted in 1872 by Swiss-Italian immigrants, Sorenson Vineyard has served as the beating heart of Burgess for more than 150 years. Climbing 800-1000 feet above sea level, this vineyard is carved into the western-facing slopes of Howell Mountain, overlooking the Napa Valley below. The landscape is dotted with large boulders on the “Konocti Series Volcanics” soil, a very densely compacted volcanic ash, as pines and redwoods surround the vineyard, becoming immersed in morning fog during the harvest months.
