Sonoma County’s Geography Can’t be Summed Up Easily
Valleys, plains, mountaintops, forests, riverbeds and ocean cliffs create a unique geographical palette resulting in a staggering amount of microclimates: trying to find one uniform characteristic to sum up Sonoma County geography is a challenge.
There are, however, a few noteworthy features that influence the winegrowing regions of Sonoma County. Long before vineyards covered the land, Sonoma County was an inland sea. Tectonic upheavals of the coastal plates created the present day Mayacamas Mountains that form the eastern boundary of the county, and created a soil structure in these areas defined by ash and lava. In addition to this rare distinction, Sonoma County is also home to more soil types than are found in all of France, creating a unique patchwork of site, soil and geographic rarities unlike any other region in the world.
Most wine regions benefit from proximity to a body of water, and for Sonoma County it’s the Russian River and the 60 miles of oceanic coastline. Meandering through a lush valley of vineyards, the rolling Russian River river provides a conduit for pulling fog through Healdsburg and into the Alexander Valley. On the west side of the county, the Russian River continues its run through Green Valley and empties into the ocean at Jenner.
A land of unlimited potential for grape growing and winemaking, Sonoma County is an inspiring place to live and work.
