Wine-Searcher – California Needs to Lose More Vines
by W. Blake Gray / Wine-Searcher

This piece from Wine-Searcher by W. Blake Gray discusses how California’s wine industry is still struggling to balance supply and demand, with grape growers and analysts saying the state needs to remove more vineyard acreage to correct a surplus of grapes and unsold wine. Even after tens of thousands of acres have been ripped out, many regions still have too many vines relative to current market demand, and growers are grappling with the economic and practical challenges of further acreage reduction. From the Article:

On Tuesday, about 100 people crowded into a conference room in Sacramento to watch a slideshow on how to stop farming wine grapes.

This is where the California wine industry is today. Allied Grape Growers president Jeff Bitter said Wednesday that he hopes California growers rip out about another 40,000 acres of vineyards this year – even though the state already has 40,000 fewer acres than it did three years ago.

To Kalon or Screaming Eagle vineyard are not being ripped out, but Cabernet Sauvignon vineyards in outlying areas of Napa Valley might be. All over Sonoma County, growers who have seen their grapes go into 90-point wines in the past are wondering if it’s time to give up and grow apples or Christmas trees instead.

Robb Report – How Napa and Sonoma Wineries Are Shifting Strategies for Millennial Tastes

Mike DeSimone & Jeff Jenssen

Mike DeSimone & Jeff Jenssen of Robb Report explore how millennials have become the largest generation of wine drinkers in the U.S. and how wineries in regions such as Napa and Sonoma are adapting their marketing and hospitality to appeal to millennial preferences. With shifting consumer behavior and declining overall consumption among younger cohorts, producers are refining tasting-room experiences, branding, and digital engagement to better resonate with this critical and evolving market segment. From the Article:

Despite all the handwringing of late that millennials ruined wine, they’ve now surpassed baby boomers as America’s largest wine-drinking generation. And in a plot twist that has surely surprised producers of ready-to-drink cocktails, spiked seltzer, and cannabis drinks, Gen Z is enjoying wine more frequently as well. 

As difficult as selling wine has become in the past several years, this generational shift provides unique opportunities for wine producers to attract younger consumers to their brands with a variety of tactics. “A ‘one-size-fits-all’ approach is unlikely to be effective,” says Wine Market Council president Liz Thach. “The most successful brands will tailor their outreach with different language, visuals, and channels.” That said, we are seeing consistent focus on sustainability and authenticity, two values that figure strongly in the millennial and Gen Z ethos. 

Wine Spectator – Arista Winery Says Adieu

In this Wine Spectator article, MaryAnn Worobiec reports on the closure of Arista Winery, the family-run Russian River Valley producer known for Pinot Noir and Chardonnay. After selling their estate property and weighing the financial and personal demands of reinventing the brand, brothers Mark and Ben McWilliams decided to wind down operations, with the 2024 vintage confirmed as Arista’s last, framing the move as a deliberate family decision rather than a symptom of broader industry distress. From the Article:

The brothers are releasing their 2023 vintage wines as normal this year and their 2024s next year. There are plans to do more events on the road and in Sonoma to celebrate with their customers. “We want to make it celebratory, not like, ‘Man, this is so sad.’ Like it is sad, there’s an element of that, but we are absolutely at peace.”

He adds that he wants to give credit to the winemaking team of Matt Courtney and assistant winemaker Gordon Miller. “They have made some exceptional wines, and it’s just been such a joy to be the platform those guys really got to show their talent and passion.”

Courtney confirms he will be focusing on his own wine brand Ferren, as well as Volterre, Amici and other consulting projects. He will also be joining the Harper’s Rest team as consulting winemaker.

WineBusiness – Monarch Tractor Abandons Ship

In this WineBusiness Monthly report, Cyril Penn details the collapse of Monarch Tractor, the once-hyped electric and autonomous tractor startup embraced by major wineries for sustainability and automation. After raising $220 million and selling hundreds of tractors, the company is effectively shutting down amid lawsuits, layoffs, and widespread reports that its tractors failed to perform as promised, leaving dealers suing, customers stranded, and inventory headed to liquidation. From the Article:

One Carneros-based winemaker said his boss purchased two Monarch tractors but described his frustration that the machines got stuck, lacked power and weren’t compatible with his tractor attachments. He said Monarch’s staff didn’t help and didn’t seem to understand farming. 

A former sales manager for Monarch told WineBusiness Monthly that in his opinion, in hindsight, the company should have treated Monarch as a prototype. “Looking back, people should have been made aware and been made a part of a journey rather than being sold a complete ready-to-go type product,” he said.

“That tractor is really a computer on wheels. And all the systems aren’t speaking the same language when you have firmware and software updates.”

2013 Curly St. James, “Ostentatious Parlay”, Napa Valley Red Blend

2013 Curly St. James, “Ostentatious Parlay”, Napa Valley Red Blend The Curly St. James “Ostentatious Parlay”, Napa Valley Red Blend is about as boutique a wine as you can get. Less than 100 cases of this Napa Valley Bordeaux-blend are produced per vintage, which makes snagging a bottle a real triumph. We were lucky enough to get our hands on a bottle of this rare wine, and, needless to say, it didn’t disappoint.

About The Ostentatious Parlay From the WineMaker – Sam Smith

While working as a sommelier in Tasmania, I was asked by visitors from the United States to describe the process it takes to make a bottle of wine. It was a great question; the truth is that it’s a long list of processes that most of us never consider when enjoying our favorite bottle. 

I explained prosaically that it begins with acquiring great land with suitable soil, and then planting the right vines. Next, wait several years for the vines to mature, harvest the grapes, crush them and make the wine. Follow this with bottling, waiting several more years to let the wine mature, and then you have something you can begin to sell. Each stage counts on the success of the previous one, and everything can be lost at any step along the way. It’s a huge gamble comprised of many individual bets. 

One guest replied with the perfect synopsis of winemaking, “That’s quite the bet. With all the moving parts it’s a parlay really, in fact I’d say it’s an ostentatious parlay.”  

There it was, the journey from land to bottle – the ultimate Ostentatious Parlay.
