TASTE News Service, December 20, 2017 – The Petaluma Gap has been officially recognized as America’s newest American Viticultural Area (AVA) by the federal government.

This grapegrowing region defines a horizontal swath in northern Marin and southern Sonoma Counties north of San Francisco.

"We are very excited to announce the official approval of the Petaluma Gap AVA in the Federal Register," said Rickey Trombetta, President of the Board of Directors of the Petaluma Gap Winegrowers Alliance (PGWA). "Being able to proudly include this designation on our labels makes it easier for consumers to seek out and identify the wines of our members. Local winemakers have long known that grapes grown in the Petaluma Gap ripen more slowly than in surrounding regions, allowing later harvest times, which results in more complex flavor development while preserving natural acidity. With today's finalization of the AVA, wine lovers and members of the wine trade will have the opportunity to become more familiar with the distinctive quality and flavor profile of Petaluma Gap wines."

The PGWA petition was submitted to the TTB in February 2015 and the proposal to establish the Petaluma Gap as an official AVA was published by the bureau in October, 2016. The final rule was published on December 7, 2017.

The Petaluma Gap AVA includes some 80 winegrowers and nine wineries, with additional fruit sold to many other wineries throughout northern California. For more information, see
