When Napa Wine Shocked The World

It's the day that changed it all, May 24th, 1976, aka the Judgment of Paris. The day a Napa wine shocked the world!

The Judgement of Paris not only put Napa Valley on the map, but it proved that wines from this upstart wine region could compete with France’s most prestigious producers. This event brought international recognition to Napa, boosted its reputation overnight, and helped establish it as a world-class wine region.

On Sunday, March 8th, 2026, I had the honor of attending a 50th anniversary MasterClass hosted by James Suckling at the Golden Gate Club in San Francisco. The focus of the tasting was nothing short of legendary: Stag's Leap Wine Cellars: 50 Years after the Judgement of Paris. The moment that forever changed the trajectory of Napa Valley.

The Tasting: Six Vintages, One Legacy

The centerpiece of the afternoon was a vertical tasting of Stag's Leap Wine Cellars SLV Cabernet Sauvignon across six vintages: 2023, 2019, 2001, 1997, 1987, and 1973.

A Quick Look Back: The Judgment of Paris

The original event, held on May 24, 1976, was organized by Steven Spurrier, a British wine merchant based in Paris. What began as a clever marketing idea, pitting California wines against France’s most prestigious bottles. Little did Steven know the impact his tasting would have, quickly becoming one of the most important events in modern wine history.

Six Napa Valley Cabernet Sauvignons were matched against four top Bordeaux First Growths, while six California Chardonnays faced off against four white Burgundies. The tasting panel? Eleven French judges, all tasting the wine blind (meaning they did not know what was in the glass). The outcome stunned the world!

Not only did Chateau Montelena (from Calistoga) win the white wine category, but the red wine category was also taken by the 1973 Stag's Leap Wine Cellars Cabernet Sauvignon, forever cementing Napa’s place on the global wine map.

The event was largely dismissed at first, with minimal press coverage. Fortunately, George M. Taber of Time magazine was present to document history in the making.

The Underdog Story That Changed Everything

What makes the 1973 victory even more remarkable is the story behind it.

The wine was produced by a young, relatively unknown winemaker, Warren Winiarski, who was previously a winemaker at Robert Mondavi Winery. In 1970, Warren and his investors purchased 44 acres of land planted with prune and walnut trees. They uprooted everything and planted Cabernet Sauvignon and Merlot; Stag's Leap Wine Cellars was born!

The vines used for the 1973 vintage were only three years old! This flies in the face of one of wine’s most persistent beliefs, that only old vines produce great wines. Yet here was a first-release wine, from a brand-new winery, beating some of the most revered estates in Bordeaux. It’s nothing short of astonishing.

A Second Victory, Decades Later, for Napa Wine

If the 1976 result wasn’t convincing enough, a 30-year re-tasting of the same wines proved it was no fluke. The wines were tasted again, both in Napa and in France, and the California wines didn’t just hold up… they excelled. The results improved, with the wines from Napa claiming the top 5 places out of 10 wines!

One of the French arguments had been that their wines were built for aging; they were too young when first tasted in 1976. This clearly was another myth, as bottle aging only strengthened California’s results.

Tasting Through Time

Back at the masterclass, the opportunity to taste the 1973 vintage was surreal. I’ve only had wines of that age a handful of times, and the evolution is profound.

With age, wine sheds its primary fruit characteristics, those bright, fresh flavors, and develops deeper secondary and tertiary notes: earth, leather, spice, and subtle oak integration.

The 1973 was fascinating for sure, but my personal favorite were the 1987 and 1997 vintages. Both showed remarkable structure and vitality for their age.

• 1997: Aromatically stunning, with beautifully layered perfume notes

• 1987: An unforgettable finish, surprisingly vibrant, herbal, and still carrying red fruit with elegance

A Rare Moment

The room itself added to the gravity of the experience. Alongside James Suckling was Tim Mondavi, who shared firsthand insights into Winiarski’s winemaking techniques and philosophies from their time working together at Robert Mondavi Winery.

Representatives of the Antinori family, the current owners of Stag’s Leap, were also on hand for the tasting. They revealed that only 20 bottles of the 1973 vintage remain at the winery from that legendary vintage. Of those, five were opened for this tasting.

Today, a single bottle in good condition can fetch between $10,000 and $15,000.

Final Thoughts

What stands out most isn’t just that California won, it’s how it won.

A new winery.

A young winemaker.

Three-year-old vines.

And yet, against all odds, they didn’t just compete, they triumphed. Even more compelling, those wines didn’t fade into history. They aged, evolved, and decades later, proved their greatness all over again.

The Judgment of Paris wasn’t just a competition. It was a turning point. It announced to the world that Napa Valley wasn’t just promising, it was exceptional. And tasting that legacy, 50 years later, was something I won’t soon forget.
