Sugarloaf Mountain

Located at the southern end of the Napa Valley, Sugarloaf Mountain resides on an exposed spine of volcanic rock. This spine of Basaltic Igneous rock, reaching out from the southern end of the Vaca Mountains, was created some 7 million years ago by volcanic activity at the triple junction of the North American, Farallon and Pacific tectonic plates. Little topsoil and exposed aspects make Sugarloaf Mountain a challenging environment for growing wine. Regulated deficit irrigation helps to keep the vines on “life support” through the latter part of the growing season while a western hillside exposure promotes late afternoon sunlight, helping to achieve sufficient solar degree days to fully ripen Bordeaux Varietals.
