Which AVA in the Central Valley is listed along with Dunnigan Hills, Capay Valley, and Merritt Island?

Clarksburg is indeed correctly identified as the AVA (American Viticultural Area) in the Central Valley that is listed alongside Dunnigan Hills, Capay Valley, and Merritt Island. The Clarksburg AVA is known for its diverse range of wines, supported by a combination of soil types and a climate that can be quite favorable for grape growing. Its proximity to the Sacramento River allows for some unique microclimates and influences on the grape varieties that thrive there, particularly for those suited to the warmer conditions of the Central Valley.

The other AVAs mentioned—Modesto, Stockton, and Fresno—are not classified as recognized AVAs in the way that Clarksburg is. While they may be significant regions within the Central Valley and could potentially have vineyards, they do not share the same level of designation or recognition for wine production that Clarksburg has achieved. This distinction is crucial for understanding the contexts and classifications within California’s wine regions.
