Earned AVA status in 1983
One of the world’s premier winegrowing regions, Los Carneros – “The Ram” in Spanish – is located less than 40 minutes from San Francisco, Marin County, the East and North Bays. Sacramento and the South Bay are both just a short distance further. A cool climate appellation, Carneros has long been known for its unassailable Chardonnays, elegant Pinot Noirs and its sparkling wines. In recent years, Carneros has been recognized for the quality of its Syrah, its Merlot and new varietals now emerging throughout the appellation.
As inland temperatures rise during the day, moist air over the cold Pacific is drawn inland over Carneros, cooling temperatures from mid afternoon into evening. These fresh afternoon winds slow activity in leaves, stressing the vines even when irrigated. Fog rolls in throughout the night and this provides a gentle buffer to the next morning’s sun, repeating the climatic cycle. Carneros was the first wine region based on climate rather than political boundaries. It received its designation in 1983.
Carneros soils tend to be dense, shallow (approximately three feet deep), high in clay content, and of low to moderate fertility. These soils impact the vine’s vigor by restricting development of the root system, providing just enough nutrients and water to sustain growth without excess development. Subsoils also vary in Carneros. Each of the different subsoils substantially changes the environment of a grapevine’s roots, and affect the composition of the fruit. Thus it is no surprise to find diversity in Carneros wines. More Info.
