About Helms Vineyard

The gently sloping site is relatively cool, protected from the intensity of the late afternoon heat in the height of the growing season. These western foothills of the Rutherford Bench are blessed with gravelly loam soils, which provide ideal drainage and are perfect for grape growing. Helms Vineyard Cabernet displays the classic Rutherford profile: dark fruit, richly layered with a touch a spice and the "dusty" character so prevalent to the appellation.
