One of the Wilson Estate Vineyards, Warm Springs Ranch is
located on the western edge of the valley at 1400 to 1600 feet. This vineyard
represents the extremes of the Dry Creek Valley appellation—rugged mountainous
terrain on the western edge of the valley. The soil is composed mainly of
volcanic clay—Laniger loam with well-drained topsoil 18 to 24 inches deep above
weathered rhyolite and rhyolitic tuff (rock composed of small volcanic
fragments compacted together). This mountainous terroir, similar to the
neighboring Rockpile appellation minus the lake influence, produces intense
fruit that translates into concentrated, richly textured and flavored white and
red wines.
