Defined by the winds of the Petaluma Gap and the minerality of the ancient sea-beds.
The terroir at Keller Estate is defined by the Petaluma Gap, a region which is subject to two major maritime influences; the San Pablo Bay lies immediately to the south, while to the northwest is an opening in the coastal hills which allows masses of fog from the Pacific to flow freely through the Petaluma Valley. This geographical signature is unique and creates a long, cool growing season for our vineyards. This climate is ideal for Pinot Noir and Chardonnay, which both thrive in cooler climates. Because of our unique terroir and our dedication to excellent winemaking, the resulting wines from our Estate vineyards are consistently well-balanced, complex and elegant.
Since the planting of our La Cruz Vineyard in 1989, Keller Estate has pursued a blueprint of clonal, or grape sub-variety, diversity based on the altitude, orientation and soil composition of each vineyard section. The diversity creates the elements on which to build textures, flavors, aromas, and ultimately complexity into the wines.
La Cruz Vineyard, where all of the Chardonnay, Syrah, Pinot Gris, and slightly over half of our Pinot Noir, are grown, resides on the lower hills of the property. The soils here are multi-layered, mineral-ladened clays that were once San Pablo Bay seabeds. This mineral character comes through in all of the wines and is very much a part of Keller Estate’s unique terroir.
