Ray Signorello founded the vineyard project in the mid 1970s by purchasing a 100-acre estate located on the Silverado Trail in Napa Valley. Ray Signorello Jr. began working in his father's winery in the mid 1980s and took over the winemaking and winegrowing for his father who passed away in 1998.
The estate consists of 42 planted acres of several different white and red varieties. The winery's Las Amigas Pinot Noir is sourced from the Carneros district of the Napa Valley. The vineyard is owned by Andy Beckstoffer and is planted to Dijon clone 113.
