Chalk Hill

The appellation, is one of 13 in Sonoma County - a region of fine wine, remarkable beauty, and agricultural abundance. Unique biospheres distinguish it from the neighboring appellations. In amazing proximity, the soils range from shallow to deep, from thin to thick, from gravel and rock to heavy clay. An old river bed caps one hill; an unusual serpentine vein ranges through another and, under the topsoil, is a layer of chalk-colored volcanic ash.
