California’s Fog Is Fading Away — Now What?

October 17, 2023

The Effects of Fog in Grape Growing in Napa Valley

Flora Springs Winemaker Enriquo Bertoz gives his opinions on the effects of Fog on Grape-Growing to Wine Enthusiast.

Fog is to central and Northern California’s wine country what garrigue is to Southern France’s—it’s an intrinsic part of California wine’s character.

Effects of Fog on Grape-Growing

Fog acts like a cool sip of water on a hot day for parched vines—not as great as a dip in the pool (rain), but better than the alternative (nothing).

“Fog acts like a stress reliever during the summer,” says Fulldraw Vineyard’s cofounder and winemaker, Connor McMahon. “In drought years especially, I love seeing fog, because it holds moisture in soil, tucks it in like a blanket. Fog can also protect grapes from the sun. In Paso Robles, it gets so hot—in August and September we had six days of 115 degrees. A little bit of fog makes a huge difference.”

But McMahon says that since 2011 when he began working in Paso, he’s seen a significant decrease in fog events. In a bid to create relief for struggling grapes, McMahon says he started using shade cloth in 2013.

“It’s essential to protect the fruit from direct sunlight when the rain and fog aren’t there,” McMahon says. “And we don’t want to overstress our water table and water the grapes all day, which is the alternative.”

Enrico Bertoz, winemaker at Napa’s Flora Springs, has also been alarmed by the drop in fog in recent years. “In the past few years, we have experienced a decline in the duration of the fog during the summer months,” Bertoz notes. “Ten years ago, the fog lasted through much of the day, and now it burns up more quickly in the morning. Where most of our vineyards are located in Rutherford and Oakville, we receive fog from both the San Pablo Bay and the Chalk Hill Gap in the Mayacamas, which is incredibly important.”

Bertoz explains that the fog helps “retain natural acidity in the grapes and prevent sunburn and heat damage.” And this year, Bertoz is happy to report, the growing season has delivered plenty of fog, something he also links to a longer growing season, which in turn ensures even ripening and full phenolic maturity.

At this point, a clear, traceable line from fog—or the lack thereof—to definitive effects on the development of grapes has not been established. Observations like Bertoz’s are backed up by one of the only comprehensive academic studies of fog’s impact on vegetation in general, published in Geophysical Research Letters.

Tracking the impact of fog through satellite imagery and remote sensing data, researchers say that fog has a “continuous positive impact” on vegetation in drier regions. Fog, the authors write, helps plants maintain “photosynthetic function and sustain biogeochemical dynamics,” and can reduce drought stress by up to 36% off the coast of southern California.

At Flora Springs, when the fog doesn’t deliver that much-needed hit of moisture, they cope by “adding plenty of water and pruning as few leaves as possible [to encourage shading] in the fruit zone to ensure as much water as possible was retained within the vines,” Bertoz explains, adding that the periodic watering helps counteract what would otherwise be an “expedited sugar ripening process.”

Take Nothing for Granted

Coming off the wettest winter in decades, winemakers are clear on one thing: Nothing is a given anymore.

Joe Nielsen, general manager and winemaker at Ram’s Gate Winery in Sonoma, concurs that fog is another shifting factor that vintners should begin to monitor.

“I come from the Midwest, and when I came to Northern California, the fog struck me as such an anomaly,” Nielsen says. “Fog is so important, because it acts as a natural air condition, and is essential for mitigating both the highs and lows of temperature during the growing season.”

Anecdotally, Nielsen says that he’s noticed differences in the fog, but says he couldn’t begin to estimate how much it has changed.

“There’s no way I could say we get 20% more or less at this point,” Nielsen admits. “It’s just clearly more erratic, along with everything else. But winemaking is just getting more refined every day, and because fog is so important to grape-growing, we definitely plan to monitor it more closely. We measure and track everything else in the vineyard—why not fog?”

“The weather has been so weird for the past years, it’s clear that we can’t take anything for granted,” says Dave Low, winemaker at Papapietro Perry in Healdsburg. “We’ve definitely noticed less fog in the past few years, but I haven’t noticed that it has led to a chemical difference in the grapes. They look the same, and they taste the same. But we are picking them a month earlier than we used to, and some of that is probably due to less fog.”

Fog, Low says, is something he plans to keep an eye on in the coming years, to establish if there is any link between a reduction of fog and changes in the glass.

“Summer Cheese, Clambake and Wine Party”
By Jill Weinlein

Summer has officially commenced, and to help celebrate the warm weather, serve a variety of cheese and wine before your clambake party!

Start with great cheese. My favorites to enjoy include Laura Chenel, a Sonoma, California producer of fresh and aged goat cheeses. Its sister brand Marin French Cheese, is California’s oldest cheese company. They have been making handmade artisan cheese at their historic creamery in Northern California since 1865. They combine traditional French cheesemaking techniques with an innovative spirit. The third is Beehive Cheese made in Utah, known as the Beehive State.

Marin French Cheese Golden Gate is a triple crème cheese offering rich and savory notes with a touch of funkiness. This cheese is best served with Flora Springs Napa Valley Family Estate wine. It was named “Best Hidden Gem Winery” in 2020 in Napa Valley Life Magazine. Founded in 1978, the estate vineyards were planted in the late 1800s. Vineyards are located in St. Helena, Oakville, Carneros, Napa Valley, Rutherford, and the Oak Knoll District. Red wines include Merlot and Cabernet Sauvignon. White wines offered include Sauvignon Blanc, Rosé and Vermentino.

National Cabernet Day 2023

April 29, 2023

Back in the days when John Komes was selling our first Single Vineyard Cabernet Sauvignons, he loved pairing each Cabernet with a different cut of premium beef. He knew what many wine enthusiasts knew intuitively: there’s simply something sublime about enjoying a juicy bite of steak with a sip of rich, ripe, tannic Cabernet Sauvignon. But he understood the science behind that magical pairing. On this National Cabernet Day, we invite you to enjoy one of our Flora Spring’s 2020 Out Of Sight Cabernet Sauvignon with a tri-tip steak with friends for the ultimate celebration. Read more.

Flora Springs Single Vineyard Cabernets

Single Vineyard Cabernets from Napa Valley were quite rare. But John Komes recognized there was something special about a group of vines – Block J – located behind his home on the northwestern edge of the Rutherford appellation. Rather than blending he kept these wine lots separate and bottled less than 50 cases on their own, beginning a tradition we’ve held to ever since. Shop Single Vineyard Cabernets.

Wild Boar Single Vineyard Cabernet Sauvignon
“41 Cabernet Sauvignons Worth Splurging On”
By Brian Freedman

These are the best bottles of Cabernet Sauvignon for your next anniversary, promotion, or big night in.

Great Cabernet Sauvignon can set you back by several mortgage payments if you’re not careful. Yet there are still plenty of splurge-worthy Cabs from around the world that ring in at under $150 per bottle…still a whole lot of money, but not in the realm of many Cab-based cult wines, or First Growth Bordeaux, which can easily stretch in to the four or five figures depending on the vintage and the provenance. The ones below, listed alphabetically, represent some of the top high-end Cabs around. They range from 2017 to 2020, and all are worth considering for special occasions as we head into the springtime holiday season of Mother’s and Father’s Day, graduations, and more. It’s also worth noting that, though a majority of these are from California, there are terrific ones that can be found from around the world, from great Bordeaux to South America, Australia, and beyond.

2019 Flora Springs Cabernet Sauvignon
There’s so much ripe, sweet, generously spiced wild red berry fruit here, like strawberries and raspberries, as well as kirsch and balsamic notes that lend this wine terrific lift and energy. These notes are for the special holiday edition bottling, a blend of two key vineyard sources, but it speaks well of the range of Cabs produced by Flora Springs, as well.

Flora Springs 2018 Howell Mountain Dust & Glory Cabernet Sauvignon in Robb Report

2018 Howell Mountain Dust & Glory Cabernet Sauvignon

“The 9 Best Napa Valley Cabernet Sauvignons From the Storied Howell Mountain Appellation”
by Mike DeSimone and Jeff Jenssen

Long before the 1976 Judgment of Paris put Napa Valley’s vinous treasure on the wine world map, bottles from Howell Mountain were taking home medals at international contests. In 1889, a wine made by Jean Adolph Brun and Jean V. Chaix, pioneers in what is now the high-altitude AVA in the northeast of the valley took home a bronze medal from the Paris World Competition. Ten years later, two other early hillside settlers, W.S. Keyes and Frederick Hess, were awarded gold and bronze medals, respectively, for their Howell Mountain wines. It took almost another hundred years for official government recognition; in 1983 Howell Mountain was named the first AVA within the greater confines of the Napa Valley AVA.

What sets this small American Viticultural Area near Saint Helena apart from many other wine regions is that its perimeter is delineated not just by geographic borders but by altitude: All vineyards must be a minimum of 1,400 feet above sea level. And while many wines from Napa and neighboring Sonoma benefit from cooling Pacific fog that rolls in each morning, Howell Mountain’s vines sit above the fog line, offering full sunlight throughout the day. Mountain conditions create berries with thick skin, offering a higher peel to juice ratio and stronger tannins. At the same time, cooler temperatures at higher altitudes aid in retaining acidity; this balanced tannin and acidity create wines that are made to last. That said, picking at perfect ripeness and a judicious use of oak means that while these will age beautifully for years, no one would fault you for opening a bottle now. Back in the day, Howell Mountain wine was likely to be Zinfandel, but today its vineyards are mainly planted with Cabernet Sauvignon and other Bordeaux varieties for blending. Among the region’s 66 member vineyards and wineries you will find familiar faces with national distribution and small volume cult wines that take a little work to acquire. Here’s a selection of Cabs to get you started…

The name Dust & Glory is to honor founder Flora Komes who often used this phrase borrowed from Mark Twain’s The Adventures of Tom Sawyer. This delightful wine is purple ink colored when poured from the bottle with very concentrated aromas of blueberry, cassis and dark chocolate. It has flavors of black plum, blackberry and a touch of bramble. The tannins are plush yet firm and the lingering finish has notes of cedar, smoke and mocha. Enjoy now until 2029.

2018 Howell Mountain Dust & Glory Cabernet Sauvignon

This is the second vintage of our Dust & Glory Cabernet Sauvignon from the Howell Mountain AVA, the first new Single Vineyard Cabernet to be added to our portfolio in over two decades. We always admired the wines of Howell Mountain, an appellation that sits to the east of St. Helena in the Vaca Mountain range. But we also learned that growing fruit on Howell Mountain comes with its challenges; the grapes are typically late-ripening and the tannins can be overwhelming. But as John and Nat Komes explored and experimented, they identified a wine from one of the highest elevation sites in the AVA that met their criteria, a beautifully expressive mountain Cabernet, distinct from our other Single Vineyards but no less prized.

Napa Valley Cabernet Vineyard

Flora Springs is one of the Napa Valley’s storied wineries. Located at the base of the Mayacamas mountain range in Napa Valley, it became famous in the 1990s, especially for its Cabernet Sauvignon. We reviewed Flora Springs wines earlier this year and were so impressed with their Legacy Cabernet Sauvignon blend that we asked to taste their portfolio of single vineyard Cabernets, which are the wines we review in this article. These are exceptionally elegant and flavorful wines. Beginning in 2019, Enrico Bertoz is responsible for the winemaking, having replaced long time winemaker Paul Steinauer, who has retired. Read our earlier article for more about what’s happening at Flora Springs including a review of their unique Soliloquy Sauvignon Blanc blend.

The 2020 Napa wildfires means Flora Springs had very limited production in that year. In short, if you want to buy Flora Springs Cabernet Sauvignon, do so now.

This Cabernet’s Aging Capacity Is Out of Sight

June 30, 2022

Out of Sight Single Vineyard Cabernet Sauvignon

Our Out of Sight Cabernet Sauvignon represents the best of both worlds: a wine that is wonderfully approachable in its youth, but with the capacity to age gracefully for five, ten, even fifteen years.

The secret? The wine’s tannin profile.

“The Out of Sight Cabs consistently have these lush, round tannins that make them immediately accessible early on,” says Winemaker Enrico Bertoz. “But these same tannins – which are essentially antioxidants – help the wines resist oxidation, which is what causes them to age.”

The quality of Out of Sight’s tannins is due both to its location and the vineyard’s soil profile. Situated on a gentle slope just north of the Coombsville AVA, Out of Sight is our southernmost Cabernet vineyard, and the soils are a beautiful gravelly loam. “The relatively cool microclimate combined with these perfect soils yield really small berries with a high skin to pulp ratio,” says Enrico. “This translates to very dark color and flavors that veer towards black fruit as well as those rich tannins.”

Because of the tannin profile, Enrico is able to leave the wine on its skin for up to two weeks after the primary fermentation is complete, a practice he began several years ago. This would be unthinkable with other Cabernets which have sharper, more angular tannins that need to be harnessed early on, but the technique works well with Out of Sight and contributes to its age worthiness.

Besides the single vineyard bottling, Cabernet from Out of Sight always makes it into Flora’s Legacy Cabernet and Trilogy. “It just always makes the cut,” says Enrico. No wonder it’s one of his favorites!

Out of Sight Vineyard, Coombsville AVA, Napa Valley

Planted on an oak-laden hillside between the Napa Valley AVAs of Oak Knoll and Coombsville, our Out of Sight Vineyard off the Silverado Trail is easily missed, hence its name. When we purchased the property in the late 1980s, the site’s gravelly soils and northwest exposure signaled great potential, but the tangled head-pruned vines also suggested years of neglect. After completely re-developing the property, however, our organically-farmed Out of Sight vineyard is today one of our most treasured fruit sources.
