Soils
At the root of Napa Valley, where it all begins. Known as one of the world’s premier winegrowing regions, Napa owes its greatness to the remarkable diversity of its soils.
Our Bourn Vineyard lies St. Helena - the heart of Napa Valley —tucked between Rutherford to the south and Calistoga to the north—where centuries of runoff from the Mayacamas and Vaca ranges have shaped soils of gravel, loam, and cobble.
