In 1934, the year after Prohibition was repealed, patriarch Edoardo Seghesio died, leaving Angela and their children to rebuild without him. They had their original 1895 vineyard at Home Ranch, but to increase production, Angela met with growers, sampling grapes and telling them exactly when to pick. This way, she identified the ranches with the best soils and, when they became available, bought them: Cloverdale in 1936, River Ranch in 1942, Cortina in 1957, Lone Oak in 1960 and Keyhole in 1962. Under Ted’s guidance, Seghesio bought Montafi Ranch in 2014.
No land was selected by accident. Each site was carefully chosen for its potential to grow world-class grapes. From these vineyards, as well as a select few owned and farmed by independent growers equally committed to excellence, we produce the highest quality wines to this day.
With only 8-16 inches of topsoil and clay soils with varying underlying layers of basalt, sandstone, and volcanic rock, vines have a difficult time surviving. Alexander Valley is characterized by warm days tempered by cooling afternoon breezes.
