Los Carneros is a Must for Wine Lovers

If you love vibrant Pinot Noir, crisp Chardonnay and elegant sparkling wines, then Los Carneros is a wine region to know.

Los Carneros offers an idyllic mix of rolling vineyards, cooling fog from San Pablo Bay and world-class wines. Thanks to its breezy climate, this wine region — straddling both Napa and Sonoma counties — has earned a reputation for producing exquisite Chardonnay and Pinot Noir.

Discover California Wines is an initiative by Wine Institute, an association of more than 1,000 California wineries and wine-related businesses. You can trust that we are knowledgeable when discussing California wine, including the Los Carneros AVA.

In this article, we will share everything you need to know about Los Carneros, from the climate, what grapes grow there, the wines they produce and where to visit!

A Historic Cornerstone in California’s Sparkling Wine Story

Also known simply as Carneros, this AVA (American Viticultural Area) stretches across the low hills of the Mayacamas Range before spilling into San Francisco Bay. While most of its vineyards are in Sonoma County, a smaller portion extends into Napa Valley, making it the only California AVA to span two counties.

The area’s viticultural history dates back to 1870 when Hungarian-American winemaker Agoston Haraszthy planted vines here. By the 1880s, Stanly Ranch had gained a reputation for its vineyards, though phylloxera soon devastated production. It wasn’t until the 1940s, when Louis M. Martini purchased and replanted Stanly Ranch that Carneros began its revival.

The turning point came in the late 1960s when grower Rene di Rosa planted his Winery Lake vineyard. He demanded premium prices for his grapes and set a new standard for Los Carneros viticulture.

By the 1970s and 80s, French Champagne houses and California producers began establishing sparkling wine operations in the area. Domaine Carneros, Gloria Ferrer and Codorniu Napa joined, capitalizing on the cool microclimates that allowed Chardonnay and Pinot Noir to retain acidity and structure — essential for crafting fine bubbly.

Today, Carneros remains one of California’s top sparkling wine regions, with rolling hills that create distinct microclimates within single vineyards, adding depth and complexity to wines.

What Makes Los Carneros Wine Great

The secret to Los Carneros’ exceptional wines lies in its climate. With its moderate temperatures and wind-swept landscape, this unique positioning makes Los Carneros one of California’s most distinct wine regions.

A thick fog blanket rolls in almost nearly every morning, shielding vineyards from direct sunlight and slowing the ripening process. The result? Fresh, balanced and complex wines.

As one of the windiest AVAs in Napa and Sonoma, Los Carneros is ideal for growing delicate varieties like Pinot Noir and Chardonnay. While Los Carneros has world-class still wines, its cool climate and slow grape ripening process make it an exceptional region for sparkling wine. More recently, winemakers have turned their attention to Syrah and Merlot, which also thrive in this cool-climate setting.

Sustainability Spotlight: Soil Health

90% of California wine is produced in a certified sustainable winery, making California sustainable wine the rule rather than the exception.

Sustainability is also at the heart of Carneros winemaking, with wineries prioritizing many sustainable practices, like soil health, to ensure the longevity of their vineyards. Healthy soil is the foundation of a thriving vineyard since nearly one-third of the grapevine’s structure exists underground as roots.

California growers enhance soil health by planting cover crops, which prevent erosion, add essential nutrients and support biodiversity. Winemakers also test soil samples to make informed fertilizer use and amendment decisions.

Incorporating organic matter like compost and reducing tillage improves soil structure, allowing for better water retention and nutrient absorption. These efforts promote healthier vines and contribute to more expressive wines that reflect the region’s unique terroir.

Recipe Inspired by California Wines

California wines pair beautifully with various dishes, from fresh seafood to roasted poultry. One standout match is this Greek Tomatoes with Orzo and Feta dish, a Mediterranean-inspired dish that pairs well with California Cabernet Sauvignon or Syrah.

When tomato season rolls around you really do need to make them the star of the show. These celebratory slow roasted tomatoes highlight their luxurious flavor while being a sturdy base for orzo pasta, tangy feta, crunchy pine nuts, and lots of fragrant herbs. All you really need to go with them is some good crusty bread to soak up the olive oil-laden juices and of course a lovely California red wine. We suggest a California Cabernet Sauvignon or California Syrah.

Ingredients

1/2 cup (89g) orzo
5 large tomatoes (1100g)
½ cup (125g) olive oil, divided
1 large yellow onion, diced (370g)
Kosher salt and freshly ground black pepper, for seasoning
1/4 cup (50ml) California white wine like a Sauvignon Blanc or Pinot Gris
2 ounces (75g) feta cheese, crumbled and divided
1/4 cup (38g) pine nuts
2 tablespoons (5g) chopped Italian parsley
2 tablespoons (7g) chopped fresh dill
1 tablespoon (3g) chopped fresh oregano
1 clove garlic (5g), chopped
1 teaspoon (5g) granulated sugar

Directions

Heat the oven to 350°F. Bring a medium saucepan of salted water to a boil over medium-high heat. Add orzo and cook a couple of minutes short of the time on the package instructions. It will finish cooking in the oven. Drain and rinse with cold water to stop the cooking. Drain again and transfer to a large bowl.
Cut tops off tomatoes and set aside. Scoop out pulp of tomatoes and chop.
Heat ¼ cup of the olive oil in a large frying pan over medium-high heat. Add onions and season generously with salt and pepper. Cook, stirring occasionally, until tender and soft and just starting to caramelize. Add wine and scrape up any bits that are stuck to the bottom of the pan. Then add chopped tomatoes. Cook until juices are thick and reduced, about 5-8 minutes. Add the onion mixture to the bowl with the orzo.
Add ¾ of the feta, pine nuts, parsley, dill, oregano, and garlic to the orzo mixture. Stir to combine. Season with salt and pepper. Taste and season again if needed.
Season the hollowed out tomatoes with salt and pepper and sprinkle the sugar over the tomatoes. Divide the mixture evenly among the tomatoes.
Pour the remaining ¼ cup olive oil in the bottom of a baking dish that fits the tomatoes snuggly. Place the tomatoes in the dish and sprinkle remaining feta cheese on top. Cover with the reserved tomato tops and bake for 45 minutes until the olive oil in the dish is bubbling and the tomato tops are lightly browned.
Serve with crusty bread and a lovely California Cabernet or Syrah, of course.

Frequently Asked Questions About Los Carneros AVA

Where is Los Carneros?

Los Carneros AVA is uniquely located at the crossroads of Northern California’s two central counties, Sonoma and Napa. It straddles the southernmost parts of these counties and is known for its cool climate, which is influenced by fog and breezes from the nearby San Pablo Bay, making it ideal for growing specific wine grape varieties.

How does the climate and geography of Los Carneros influence its wine styles?

The climate in Los Carneros is significantly cooler and more temperate than the warmer inland AVAs, primarily due to the maritime influence from San Pablo Bay.
