Sonoma County is 52 miles wide and 47 miles long and is currently home to 260 wineries. On the east, Sonoma County borders Napa Valley along the Mayacamas Range. About two million years ago, volcanic eruptions deposited a series of ash and lava called the Sonoma Volcanics throughout much of Sonoma and Napa Counties, especially along the Mayacamas Range. The western edge of the County is the California coastline along the Pacific Ocean. Sonoma County borders Mendocino County in the north and Marin County in the south.

Luther Burbank called Sonoma County “the chosen spot of all the earth as far as nature is concerned.” A vastly diverse range of topography, including numerous small valleys with distinct microclimates, the Russian River and the Pacific Ocean, all characterize the region. A moderate climate with a cooling maritime influence, Sonoma County embodies ideal and diverse grapegrowing weather: from valley to hillside, moist ocean coast to dry inland, and cool southern regions that complement the warmer, more northern areas.
