Coombsville Vintners & Growers

MARITA´S VINEYARD is located in the Coombsville area of Napa.

Coombsville is the newest American Viticultural Area (AVA) in the Napa Valley.

The “Coombsville” AVA is an area just east of the city of Napa that encompasses 11,000 acres from the Napa River to the eastern rim of the Napa Valley in the Vaca Range.

Vineyards in the area are mainly in the rolling benchlands that dominate the topography which provide an array of viticultural microclimates and, therefore, many possibilities for varietal selection. Chardonnay and Pinot Noir thrive in the lower swales and small valleys while Merlot, Syrah and Cabernet dominate the hillsides.

The climate of Coombsville is very temperate due to its close proximity to the San Francisco Bay. The cooling effects of maritime fog are felt earlier and last longer than the Upvalley sub-AVAs. Also, temperatures are moderated during the cold winter months and during frost season. As a consequence, budbreak is often sooner and harvest slightly later which lead to a longer overall growing season. Another factor is moderation during heat waves which lessens sunburn and severe vine stress issues.

The geology and resultant soils are dominated by the volcanic “rhyolitic tuff” that comprises the Vaca Range on the eastern side of the Napa Valley. The weathered hillsides form wide alluvial deposits where most of the vineyards are located. These soils are abundant with rock and gravel and, in some areas, are also layered with volcanic ash deposits also common in other parts of the Napa Valley. Together, the two main soil types present additional factors for an array of planting decisions specific to each site.

The unique combination of climate and soil makes Coombsville and ideal locale where to grow Bordeaux varietals that have been the source of world-class wines produced in Napa Valley.

Almost all of Coombsville wineries are family-owned and operated by people who take pride in the distinctive wines we produce. Any visitor to our region may confidently expect personalized hospitality, often by the owners of the property.
