Petaluma Gap

During the 1990s, the Sonoma County wine industry adopted the term Petaluma Gap to help differentiate its products. The Petaluma Gap has filed a petition to become its own AVA, but languished as the TTB considered its fate.  It remained a part of the Sonoma Coast AVA until December 2017 when AVA status was granted. 

Wine grapes growing in the Petaluma Gap are said to be influenced enough by this climate to give the area's wines a distinctive character. Mornings in the region tend to be foggy, followed by sunny days and windy afternoons. The cool evening temperatures help to preserve the natural acidity of the grapes over an extended growing season. The cool climate and daytime sun make this region perfect for growing Pinot Noir,  Chardonnay, and Syrah.
