The Napa Valley Nobody Talks About

November 29, 2016 · Updated July 2, 2026 · 11 min read

Napa Valley produces roughly 4% of California’s wine grapes and generates approximately 17% of the state’s wine revenue — and the reason for that disproportionate financial power is almost entirely Cabernet Sauvignon. When a grower can command two to ten times more per ton for Cabernet than for any alternative variety, the economic pressure toward monoculture is nearly irresistible. But for those rare Napa producers willing to farm something else — old-vine Zinfandel surrounded by tract houses, Chenin Blanc on the verge of local extinction, Petite Sirah that nobody’s heard of — the wines that emerge can be among the most interesting in California. This is the Napa Valley most visitors never find.

Key Takeaways

Cabernet Sauvignon now accounts for more than 60% of all Napa Valley plantings — Economic pressure has driven out nearly every alternative variety that once gave the valley genuine diversity. Zinfandel now comprises less than 3% of Napa’s grape production.
Robert Biale Vineyards is the most important Zinfandel producer in Napa — and one of the only ones left — Founded in 1991 around Aldo’s Vineyard, head-trained Zinfandel vines planted in 1937, Biale makes 20+ single-vineyard Zinfandels and produces zero Cabernet Sauvignon. In a valley defined by one grape, this is a genuine act of defiance.
The Black Chicken story is one of the great Prohibition-era wine tales — Teenage Aldo Biale kept his family going during the Depression by selling bootleg Zinfandel over the party-line phone as “Black Chickens.” Those same vines are still producing 90-year-old fruit today.
Chenin Blanc has nearly vanished from Napa — In the early 1980s there were approximately 2,000 acres of Chenin Blanc planted in the valley. Today fewer than 14 acres remain. A handful of producers, including Lang & Reed Wine Co., still make it.
Old vines cannot be replaced — A Zinfandel vine planted in 1937 took 87 years to develop its root system, its water access, and the concentrated, complex fruit character it now produces. When the pressure to replant with Cabernet finally wins — and it eventually does, vineyard by vineyard — that specific character is gone permanently.

Why Did Cabernet Take Over Napa Valley?

The Napa Valley of the 1960s and 1970s was genuinely diverse. Vineyard blocks of Pinot Noir, Gamay, Zinfandel, Petite Sirah, Riesling, Chenin Blanc, and Gewürztraminer dotted the valley floor alongside Cabernet. Growers farmed what grew well in their specific soils and microclimates, and the valley’s wine identity was still being discovered rather than defined.

What changed was economics — and the economic force behind it was decisive and essentially irreversible. As Napa Cabernet Sauvignon established its reputation in the late 1970s and 1980s, particularly after the 1976 Paris Tasting that showed California wines could compete with the best of Bordeaux, the price premium for Cabernet grapes began to diverge dramatically from everything else. When a vineyard owner can command two to ten times more per ton for Cabernet than for Zinfandel, Chenin Blanc, or Riesling, the financial calculus for replanting becomes difficult to argue against — especially when that vineyard represents the family’s primary asset and income.

The Numbers

How Completely Cabernet Dominates Napa Today

Cabernet Sauvignon now accounts for more than 60% of all Napa Valley grape plantings. Zinfandel — once widely planted across the valley by immigrant Italian and Croatian farming families who had grown it for generations — now comprises less than 3% of Napa’s total grape production. Chenin Blanc, which had approximately 2,000 acres planted in the early 1980s, has fewer than 14 acres remaining in the entire valley. Pinot Noir, Riesling, Gewürztraminer, and Gamay have largely disappeared from Napa altogether, pushed out acre by acre over four decades of relentless economic pressure toward the single variety that commands the highest price per ton.

The result is a valley that makes spectacular wine — Napa Cabernet at its best is genuinely among the finest red wine in the world — but that has sacrificed the diversity that once made it interesting in a different way. The producers who refused to make that trade, who continued farming old-vine Zinfandel or impossibly rare Chenin Blanc despite the financial pressure, made a choice that deserves to be understood and supported.

Robert Biale Vineyards — The Zinfandel Holdout

In the heart of Napa’s Oak Knoll District, surrounded by Cabernet Sauvignon vineyards pressing in from every direction and residential neighborhoods encroaching from the other side, sits Aldo’s Vineyard — 23 acres of head-trained, non-irrigated Zinfandel vines planted in 1937. This is the oldest Zinfandel vineyard in the Oak Knoll District, and incidentally, the neighborhood where Zinfandel was first planted in all of Napa Valley, in 1852, by Captain Joseph W. Osborne.

Robert Biale Vineyards was founded in 1991 by Bob Biale, Dave Pramuk, and the then-elderly Aldo Biale — third, first, and second generation of a family that had been farming this Zinfandel since the 1930s. Their goal was straightforward and, in the context of 1991 Napa Valley, slightly countercultural: produce world-class wine from the oldest Zinfandel vines on the Biale ranch, and prove that Zinfandel deserved to be taken as seriously as the Cabernet that was swallowing the valley around them.

More than three decades later, under winemaker David Natali, Biale produces a portfolio of 20+ single-vineyard Zinfandels and Petite Sirahs that are featured on A-list restaurant wine lists from coast to coast, alongside newer additions including possibly the only old-vine Barbera in all of Napa Valley. The winery makes zero Cabernet Sauvignon. In a valley defined almost entirely by one grape, this is a statement as much as it is a business decision.

“I feel a sense of gratitude and good fortune,” Bob Biale has said. “My grandparents landed in Napa Valley with the dream to own a parcel of land and to plant a vineyard during a time when Napa was removing vineyards for more profitable fruit crops. There are not too many opportunities in life that allow one to tangibly connect with past generations in a family.”

The Black Chicken Story

The history behind Biale’s flagship wine is one of the more remarkable stories in American wine. Pietro Biale, who had emigrated from Genoa, Italy, was killed in a rock quarry explosion in 1942, leaving his 13-year-old son Aldo and his widow Christina to keep the ranch operational. They sold eggs, vegetables, prunes, and white leghorn chickens from their farm. And, in order to keep the family solvent, Aldo began making and selling Zinfandel — illegally, being both underage and unlicensed — to trusted neighbors.

The challenge was communication. In those days, neighbors shared party lines — telephone connections where anyone on the line could listen to anyone else’s conversation. Aldo needed a code. When customers called to order produce, a request for a “Black Chicken” — Gallina Nera in Italian, adapted from Chianti’s symbolic Gallo Nero rooster — meant a jug of Zinfandel. Nosy neighbors heard nothing more alarming than a farm family discussing poultry.

Those bootleg jugs sustained the Biale family through the postwar years. The vines that produced them are now 87 years old, still head-trained and non-irrigated in the original configuration, still producing concentrated and complex fruit that no newly planted vineyard can replicate for decades. Black Chicken Zinfandel remains Biale’s most widely available wine — the 2024 vintage was described by James Suckling as “gorgeous, with dark-fruit flavors wrapped in velvety tannins, showing blackberries, dark chocolate, baked plums, hints of black pepper and cloves.” The history is part of what you taste, even if you don’t know it’s there.

Why Old Vines Matter

The phrase “old vines” appears on wine labels often enough that it risks becoming marketing shorthand rather than meaningful information. But in the specific context of Napa Zinfandel, it describes something genuinely irreplaceable.

Definition

Head-Trained, Non-Irrigated Old Vines

Head training is one of the oldest vine management systems in viticulture — a low, free-standing bush form with no trellising, where the vine’s canes radiate from a single head or trunk. Combined with dry farming (no irrigation), this system forces vines to develop extremely deep, expansive root systems in search of water, sometimes extending 30 feet or more below the surface. Old vines managed this way over decades of non-irrigated farming develop root access to subsurface water and mineral deposits that younger vines simply cannot reach. The result is lower yields of smaller, more concentrated berries that produce wines with a depth and complexity — what some describe as “nuance” or “mystery” — that cannot be replicated in younger plantings regardless of winemaking technique. There is no American Viticultural legal definition for “old vines,” but the general industry consensus holds that vines must be at least 25 years old to use the designation, with the most meaningful expressions typically coming from vines 50 years old or more.

David Natali, Biale’s winemaker, and his predecessors have spoken consistently about what these old vineyards offer that no replanted Cabernet block can: “Zinfandel in general, and old vines in particular, can produce wines that never cease to amaze me in their complexity and depth. Every single old vine is like a sacred old soul that has so much to say if we’d just take some time and listen. When they’re gone, they cannot be replaced.”

Biale’s portfolio extends well beyond Aldo’s Vineyard, sourcing from some of the oldest vineyard sites in both Napa and Sonoma — Beatty Ranch on Howell Mountain, the Grande Vineyard from 1920 plantings, Dickerson Vineyard from the 1920s in St. Helena, and Falleri Vineyard in Calistoga planted by Argentine immigrant Argentina Falleri in 1924 and still cared for by her granddaughter today. Each vineyard is a specific piece of California agricultural history. Each one is under pressure.

The Near-Extinction of Napa Chenin Blanc

If old-vine Zinfandel represents the most visible victim of Napa’s economic consolidation around Cabernet, Chenin Blanc is the quieter one. In the early 1980s there were approximately 2,000 acres of Chenin Blanc planted in the Napa Valley — a significant presence for a variety with deep California roots, extensively planted by the immigrant farming families who understood that its natural acidity, food-friendliness, and versatility in style made it an excellent everyday wine for the California table. Today, fewer than 14 acres of Napa Chenin Blanc remain.

The producers still making it are doing so as an act of genuine commitment. John Skupny, proprietor of Lang & Reed Wine Co., has been one of the most prominent voices for Napa Chenin Blanc — reflecting on how completely the variety has been erased from the valley he arrived in four decades ago. The remaining Napa Chenin Blanc tends to share the Loire Valley characteristics that made the variety famous in France: bright acidity, honeyed stone fruit aromatics, and a refreshing tartness that makes it one of the most food-friendly white wines produced anywhere in California.

The larger irony is that Chenin Blanc is experiencing a global renaissance outside Napa — South Africa’s Swartland region has made it the signature white wine of its natural winemaking movement, and Loire Valley Chenin Blanc from Savennières and Vouvray commands serious prices among wine collectors. But in the valley where it was once widely planted and genuinely beloved, it has been replaced — largely by Chardonnay, which now occupies more than 7,000 acres of Napa plantings versus Chenin Blanc’s 14.

Frequently Asked Questions About Napa Valley Beyond Cabernet

Napa’s Other Varieties: Common Questions Answered

Why is Zinfandel so rare in Napa Valley now?

Economic pressure toward Cabernet Sauvignon, which commands two to ten times more per ton than Zinfandel, has driven Zinfandel out of Napa Valley almost entirely over the past 40 years. Zinfandel now comprises less than 3% of Napa’s total grape production. The few old-vine Zinfandel blocks that remain survive because of the specific commitment of their owners — families like the Biales who have been farming the same vines for generations and have refused to replant despite significant financial incentive to do so.

What is the Black Chicken story at Robert Biale Vineyards?

In the 1940s, teenage Aldo Biale helped keep his family’s Napa ranch going after his father’s death by selling homemade Zinfandel to trusted neighbors — illegally, since he was both underage and unlicensed. To communicate over the shared party-line phone system without alerting eavesdroppers, customers would request a “Black Chicken” (Gallina Nera in Italian) alongside their produce orders, signaling a jug of wine. Those same Zinfandel vines, planted by the family in 1937, still produce fruit today and form the foundation of Biale’s Aldo’s Vineyard bottling.

What makes old-vine Zinfandel different from younger plantings?

Old vines, particularly those that are head-trained and dry-farmed without irrigation, develop extensive, deep root systems over decades that access subsurface water and mineral deposits younger vines cannot reach. This produces lower yields of more concentrated, complex fruit. The resulting wines typically show greater depth, nuance, and what many tasters describe as “mystery” compared to wines from younger plantings — characteristics that cannot be reproduced through winemaking technique alone. Once an old vine block is replanted, that specific character is permanently lost.

Does Robert Biale Vineyards make Cabernet Sauvignon?

No — Robert Biale Vineyards produces zero Cabernet Sauvignon, making it one of the only significant Napa wineries with no Cabernet on the premises at all. The portfolio focuses entirely on Zinfandel and Petite Sirah from heritage vineyard sites across Napa Valley and Sonoma County, with 20+ single-vineyard bottlings that span from Aldo’s Vineyard (Oak Knoll District, 1937 plantings) to high-elevation sites on Howell Mountain and Atlas Peak.

What happened to Chenin Blanc in Napa Valley?

Chenin Blanc was extensively planted in Napa Valley through the early 1980s, with approximately 2,000 acres in production. As Chardonnay’s popularity grew and economic pressure toward premium varieties intensified, Chenin Blanc was almost entirely replaced — today fewer than 14 acres remain in the entire valley, compared to more than 7,000 acres of Chardonnay. A small number of producers including Lang & Reed Wine Co. still source and produce Napa Chenin Blanc from the remaining vineyards.

Where can I find Biale wines?

Robert Biale Vineyards wines are available through the winery’s website, their wine club, and select retail shops and restaurant wine lists nationally. The flagship Black Chicken Zinfandel is the most widely distributed; single-vineyard bottlings like Aldo’s Vineyard are produced in smaller quantities and may require purchasing directly through the winery or joining their mailing list. Visiting the winery in Napa’s Oak Knoll District — where you can taste on the back porch overlooking the vineyards — is the most rewarding way to explore the full range.
