Climate
Protected by surrounding hills, Chalk Hill forms a warm pocket that experiences less marine influence than western Sonoma Coast appellations, resulting in warmer daytime temperatures and greater diurnal temperature variation. The eastern exposure captures morning sun while the white volcanic soils reflect heat, creating optimal ripening conditions for both Chardonnay and Cabernet Sauvignon.
Terroir
Chalk Hill sits atop volcanic ash deposits from ancient eruptions, creating distinctive white chalky soils mixed with clay sediments. The porous volcanic ash provides excellent drainage while the underlying clay layer retains moisture, allowing vine roots to penetrate deep while maintaining consistent water access during dry periods.
