Vineyard Notes
Petaluma Gap, defined by its unique wind and fog conditions and their effect on vines, was designated as an AVA in 2017. Known for a mild Mediterranean climate, the Petaluma Gap is characterized by warm, dry summers and cool, wet winters. The Estero Lowlands and a series of low hills form a transport corridor that allows marine air to circulate into the region from the western-most boundary along the coastline. Summer is characterized by a distinctive, crisp coolness and a blanket of morning fog that is chased away by the sun causing temperatures to rise. The cool, on-shore breezes begin by mid-afternoon picking up speed as the day progresses to bring in fog almost every night. The cooling “wind
tunnel” effect distinguishes the Petaluma Gap as its own AVA. This results in lower yields and grapes that reach physiological ripeness later but at lower sugar levels allowing the fruit to develop wonderful flavors and ideal levels of acidity. This makes it one of California’s best areas for growing complex and elegant Pinot Noir.
