Northern Sonoma - Catch all northern region, includes Alexander valley, chalk hill, dry creek, knights valley, RRV, and sonoma green valley. City of santa rosa is the limiting line.

Russian River Valley
- early morning coastal fog makes for cooler growing season and perfect for PN

Sonoma Coast - the western boarder of the Sonoma AVA, right along the pacific coast, lots of fog and significantly cooler.

Sonoma County-Green Valley - in the RRV, sandy loam, ideal for Sparkling wine. so named to avoid confusion with Green Valley in Solano County

Sonoma Mountain - thermal belt drains the fog and cold air, resulting in more moderate temperatures.

Sonoma Valley - lowest rainfall in the county, and fog rarely penetrates. Red wine country. Cab Sauv and Zin.
