Carneros Wineries And Wines
Although Carneros Wineries are located in both southern Napa and
Sonoma Counties, the region has always had its own unique
identity. Being a huge Pinot Noir fan, I really enjoy exploring
new, interesting wines from this region.
Carneros is an example of an AVA that has a more uniform terroir
than most. Whereas the borders of some AVAs have been extended
beyond their natural climactic boundaries because of politics
and influence, Carneros resisted this all too common tendency.
History
During the Spanish era of California, the region was a natural
place for settlement in the North Bay due to its proximity to
San Francisco, and accessibility by water routes. When General
Vallejo secularized the Spanish Missions in 1834, he divided the
region amongst several of his cronies. The area was initially
developed to produce subsistence crops and livestock.
The first vineyards were planted in the 1830s, and Carneros
Wineries flourished for many decades until phylloxera devastated
the region's grapes along with most vineyards throughout
California.
Prohibition appeared to be the last nail in the coffin for
Carneros Wineries. After this unfortunate law's repeal, Andre
Tchelistcheff and Louis M. Martini took an interest in the
region's unique climate. Investment in Carneros Wineries was
slow until the 1970s when it began to surge with the rest of the
Napa Valley.
Terroir
Regular fog derived from the San Pablo Bay and Napa River has a
cooling effect on the region. Wind is a constant factor, and it
blows relatively unobstructed throughout most of the AVA.
Additionally, rainfall is relatively scarce, causing most
Carneros Wineries and growers to irrigate their crops. The lack
of abundant fresh water as well as the encroachment of sea water
into some parts of the ground inhibit rampant vineyard expansion.
As one moves north from the San Pablo Bay, rolling hills begin
to replace the extremely flat terrain in the south. There are a
few hills that rise to 1000 feet, but they do little to shield
the wind and fog. Because of Carneros' consistant climate,
certain varietals grow in a very methodical manner.
A multitude of fossilized sea life exists in the soil, and is
reminiscent of when the San Pablo Bay covered much of the
region. The soil has relatively low fertility, giving grape
vines only enough nourishment to focus on scarce, concentrated
fruit. The soils of Carneros are generally made of relatively
compact clay and are quite shallow.
Varietals, Wines, and Wineries
Pinot Noir and Chardonnay are quite compatible with the terroir
of Carneros, and the AVA produces some great examples of these
two varietals. About 80% of the grapes produced here are either
Pinot Noir or Chardonnay. Carneros Wineries also produce some
excellent sparkling wines. Some parts of the region have also
had a degree of success producing Merlot and Syrah in the
northern, slightly warmer parts of the AVA.
