Los Carneros

Wines to know in Los Carneros

Los Carneros is one of the coolest spots around due to its proximity to cool waters in San Pablo Bay. Straddling both Napa and Sonoma counties, this AVA is one of the few that doesn’t focus on Cabernet Sauvignon, mainly because it’s too cool to ripen properly.

What we have instead is the perfect climate for early ripening varieties like Pinot Noir and Chardonnay. These Burgundian varieties are perfectly at home here, with some vineyards just one mile from the Bay.

The cool afternoon breezes and morning fog means it rarely gets above 80 °F here (26 °C) - paving the way for elegant styles of Pinot Noir and Chardonnay, both with refreshing acidity and potential for cellaring.

Pinot Noir and Chardonnay are also the perfect pair for producing sparkling wines. If you’re looking for something to rival Champagne then look into Los Carneros. These wines, made using the same method and grape varieties as found in Champagne, have a fine mousse, mixture of red and green apple, lemon curd, baking spices, and brioche notes with a fresh linear finish.

Los Carneros AVA Terroir

With its proximity to the cool San Pablo Bay bringing morning fog and cooling afternoon sea breezes blowing through the Petaluma Gap, Los Carneros is one of the coolest spots in Napa Valley.

Most vineyards are between one and four miles from the bay, meaning that with an average temperature during the growing season is only 72° F (22° C), it’s quite well suited to varieties that like more moderate climates, such as Pinot Noir, Chardonnay, but also Albariño, and Pinot Gris.

Though there may be cooling influences there’s not a lot of rain, with only 25 inches of rain (640 mm), most of which falls during the winter months.

Thankfully, the clay topsoils found here hold moisture, which means vineyards don’t need to irrigate as much as you think. The loamy soils, particularly near Carneros Creek, are perfect for acid retention, which is a key component to producing high-quality sparkling wines.
