Defined by its unique wind and fog conditions and their effect on the vines, the Petaluma Gap was designated in 2017 as an American Viticultural Area (AVA). The Petaluma Gap produces premium grapes that make it one of California's best areas for growing Pinot Noir, Chardonnay, and Syrah. Just 25 miles north of San Francisco's Golden Gate Bridge, it's also the premier gateway to the Sonoma Coast and northern Marin County wine region. Keller Estate is the Petaluma Gap's founding member.

The winning bidder receives a tour and tasting for 2 people. A peaceful walking tour of the Keller Estate grounds gives way to a comfortable seated wine tasting experience. The tasting features a selection of estate grown Chardonnay, Pinot Noir, Syrah and Pinot Gris.
