One of the largest and historically most important winegrowing areas in California ( North Coast region). It is divided into partly overlapping AVAs and sub-AVAs. Without going into the hierarchical order, these are, in alphabetical order, Alexander Valley, Alexander Mountain, Bennett Valley, Chalk Hill, Dry Creek Valley, Knights Valley, Los Carneros, Northern Sonoma, Rockpile, Russian River Valley, Sonoma Coast, Sonoma County Green Valley, Sonoma Mountain and Sonoma Valley. There is no overarching AVA designation. The area extends north of San Francisco between Napa County and the Pacific Ocean. The climate ranges from warm in the north (climate region III) to cool in the south (I) due to the Pacific Ocean. The diverse soils consist of clay, alluvial soils, limestone and volcanic soil.
The wein.plus encyclopaedia is a comprehensive, well-researched reference work. Available anytime and anywhere, it has become an indispensable part of teaching, used by students and myself alike. Highly recommended!
