Tom Burgess established Burgess Cellars in 1972, but these Howell Mountain slopes were first planted in the 1870s by Italian-speaking immigrants from the Swiss canton of Ticino. The Poncetta & Rossini families, in the way of their Alpine homeland, cultivated vines on the rugged mountainside at extreme elevations. With the same ambition and imagination, Lee Stewart planted Cabernet Sauvignon and Petite Sirah grapes on Howell Mountain’s steep hillsides, naming his winery Souverain, meaning “sovereign.” Subsequent Napa Valley greats also saw the high promise of the land. Before starting the historic Stag’s Leap and Grgich wineries, Warren Winiarski and Mike Grgich each learned his trade at the Estate known today as Burgess.
