The Petaluma Gap has a 150-year tradition of growing grapes. The Petaluma Gap Winegrowers Alliance is dedicated to supporting growing wine grapes and production of premium wines in the Petaluma Gap. Our vineyards are tucked and hidden in the most unexpected places. Crest a hill, round a curve, look into the little nooks and crannies that make up the Lakeville, Adobe Road, or west county landscape, and you’ll notice more and more pockets of green, made up of rows and rows of grapevines. The vines bring brilliant patches of color to the golden grasses that support the neighboring pastures of cows and sheep. These are the vines of the Petaluma Gap and the source of some of the most exciting wines to hit the California wine scene in a very long time.
