HOWELL MOUNTAIN: Appellation
"If any grape growing region in California deserves to be called a well-defined district, it is Howell Mountain." — St. Helena Star, circa 1880
A century after the Star's report, in 1983, the Howell Mountain American Viticultural Area (AVA) became the first official sub-appellation of Napa Valley. Where rivers, creeks and property lines usually define an AVA, the Howell Mountain boundaries are defined by a 1,400 foot elevation contour line as the lowest point and the highest vineyards at 2,400 feet above sea level. The vines share the mountain with pines, oaks, madrone and the easternmost stand of the coastal redwoods.
