In 1954, a family winery in Dry Creek Valley started bleeding juice off its red Zinfandel to make a pale, fruity rosé. Eighteen years later, a winemaker at a Napa winery did something almost identical, called the result “White Zinfandel,” and got all the credit for inventing an entire category. Sonoma County made this wine first. It just never got famous for it.
That’s worth untangling, because “White Zinfandel” is one of the most misunderstood names in wine — and Sonoma’s version of the story is a lot more interesting than the one most people know.
What “White Zinfandel” Actually Is
White Zinfandel isn’t a white wine, and it isn’t made from a white grape. It’s a blush-pink wine pressed from the same red Zinfandel grapes that go into big, jammy red Zins all over Sonoma County — the pink color comes from a few hours of contact with the grape skins before the juice is drawn off, not from the grape itself.
There’s no such thing as a “white Zinfandel grape.” Zinfandel is a red-skinned variety, and DNA work at UC Davis in the late 1990s (led by geneticist Carole Meredith) confirmed it’s identical to Italy’s Primitivo and traces back to a Croatian grape called Tribidrag. Every bottle labeled White Zinfandel starts as a red grape that’s simply pressed and fermented like a white wine.
For most of the grape’s history here, nobody knew any of that. Zinfandel arrived in California with East Coast nursery stock during the Gold Rush of the 1850s, and Dry Creek Valley — Pedroncelli’s home ground — was among the first places in Sonoma County to plant it, with growers putting in vines there in the 1860s. For more than a century after that, nobody could say with certainty where the grape had come from before it reached Boston’s greenhouses. It took Carole Meredith’s DNA fingerprinting, comparing vine samples across three continents, to finally trace it to Croatia. Dry Creek Valley’s oldest Zinfandel vines predate that answer by well over a hundred years.
The technique has a name: saignée, French for “bleeding.” Winemakers draw off a portion of free-run juice early in a red wine’s fermentation, before much color or tannin has extracted. What’s left behind ferments into a more concentrated red. What’s drawn off — pale, fruity, low in tannin — becomes the rosé.
That single technique produces two very different wines depending on how it’s finished. Ferment it fully dry and you get a crisp, food-friendly rosé. Stop the fermentation early with residual sugar still in the wine — intentionally or by accident — and you get the sweeter, softer style most people picture when they hear “White Zinfandel.”
Sonoma Was Doing This Before Napa “Invented” It
The popular origin story belongs to Napa. In 1972, Bob Trinchero at Sutter Home Winery in St. Helena drew off some free-run juice from his Amador County Zinfandel, hoping to concentrate the red wine left behind. He bottled the pale pink runoff as an experiment. By 1975, a batch of it stuck mid-fermentation — the yeast stalled out before converting all the sugar to alcohol — and the accidentally sweet, pink result sold out. Trinchero kept making it. By 1987, Sutter Home White Zinfandel was the best-selling premium wine in the United States, and it held that title for over a decade.
It’s a great story. It’s also not the first time anyone in California made this style of wine — and Sonoma County has the paperwork to prove it.
Pedroncelli Winery, a family operation in Dry Creek Valley since 1927, started making a Zinfandel-based rosé from its home ranch and Bushnell Vineyard fruit in 1954, releasing the first vintage in 1955. The family’s own history credits it as the first rosé wine made from Zinfandel — nearly two decades before Trinchero’s stuck fermentation in Napa. Pedroncelli has made a rosé from Zinfandel every year since, a run now past 70 consecutive vintages.
Here’s the part that says the most about how the two wines diverged: around 2007, Pedroncelli renamed its wine. It had been calling it Vin Rosé and later Zinfandel Rosé, but as “White Zinfandel” became shorthand for the syrupy, mass-market style pouring out of Napa and the Central Valley, Pedroncelli rebranded to Dry Rosé of Zinfandel — a deliberate signal that its version bears almost no resemblance to the supermarket stuff. Same grape, same basic technique, opposite finishing decision, and a name change built entirely around the difference.
If that contrast has you curious what a properly made, food-worthy Zinfandel rosé actually tastes like — as opposed to the sweet, low-alcohol stuff gathering dust in the grocery aisle — Dry Creek Valley is where to start looking. That AVA is where this style has the deepest roots in the county.

Where to Actually Taste It in Sonoma County
Our directory currently lists close to 200 Sonoma County wineries that grow Zinfandel, but the overwhelming majority of that is red wine. Only a handful still bottle the pale, bled-off style at all, and it’s worth checking a winery’s current release list — or just asking at the tasting bar — before you drive out expecting it. A few worth knowing by name:
- Pedroncelli (Dry Creek Valley) — the original. Its Dry Rosé of Zinfandel, sourced from the Bushnell Vineyard’s rocky, well-drained hillside soils, is still fermented fully dry in stainless steel with no oak contact.
- Halleck Vineyard (Sebastopol, Russian River Valley) — pours a wine it still calls Dry White Zinfandel, and says so plainly: too pink to be a white wine, not pigmented enough to be a red.
- Truett-Hurst (Healdsburg, Dry Creek Valley) — a biodynamic, Zinfandel-focused winery along Dry Creek that rounds out its red Zin program with a rosé.
- St. Francis Winery (Sonoma Valley) — makes an estate Zinfandel rosé from its Ranch Rio Este vineyard that’s picked specifically for the rosé program rather than bled off a red-wine tank.
If you’re building a Dry Creek Valley day around this, our weekend planning guide already routes a Zinfandel-focused itinerary through the valley for the reds — Pedroncelli sits comfortably on the same loop for the rosé side of the story.
How to Taste It Like You Know the Difference
A few things worth knowing before you order a glass:
Ask which style before you taste. “White Zinfandel” and “rosé of Zinfandel” can describe wines that taste nothing alike. If a tasting room pours something in this category, ask whether it’s dry or off-dry — the answer tells you more than the name on the label does.
Serve it cold, but not ice-cold. Around 45–50°F works for the dry Sonoma style — cold enough to stay crisp, warm enough that the fruit and spice notes actually show up. Standard white wine glassware is fine; you don’t need anything wider.
Pair by sweetness level, not by color. A dry Sonoma rosé of Zinfandel — think strawberry, watermelon, a little white pepper — works well with grilled chicken, charcuterie, salmon, and dishes with real heat, the way a good rosé from Provence would. The sweeter, mass-market style is traditionally poured alongside spicy Tex-Mex or barbecue, where the residual sugar tempers the heat rather than fighting it.
Check the alcohol level if you’re comparing bottles. The famous grocery-store style typically lands around 9–10% ABV — light on purpose. A dry Sonoma version usually runs closer to 13.5–14%, in line with most table wine. That’s a real difference in the glass, not just a marketing choice.
Most Sonoma producers release their rosé of Zinfandel in spring and pour through the summer, so the window to taste a current vintage is real but not year-round. We’ll flag new releases and harvest-season events as they’re announced, so you don’t have to keep checking back.
Frequently Asked Questions
Is White Zinfandel a red or white wine?
Neither, technically — it’s a rosé. It’s pressed from red Zinfandel grapes, but the juice spends only a few hours in contact with the skins before it’s drawn off, which tints it pale pink without extracting enough color or tannin to make it a red wine.
Who invented White Zinfandel?
Sutter Home in St. Helena, Napa Valley, gets the popular credit: winemaker Bob Trinchero bottled a pink, sweet Zinfandel after a stuck fermentation in 1975, and it became the best-selling wine in the U.S. by 1987. Sonoma’s Pedroncelli Winery, though, had been making a Zinfandel rosé in Dry Creek Valley since 1954 — eighteen years earlier.
Is White Zinfandel always sweet?
The famous mass-market style is off-dry to sweet, but that’s a finishing choice, not a rule of the style. Sonoma producers like Pedroncelli ferment theirs fully dry, which is exactly why many now market it as “rosé of Zinfandel” rather than “White Zinfandel” — to signal that difference up front.
Is Zinfandel a red or white grape?
Zinfandel is a red-skinned grape, genetically identical to Italy’s Primitivo and traced by UC Davis DNA research to a Croatian variety called Tribidrag. There is no “white Zinfandel grape” — the wine’s pale color comes from limited skin contact during winemaking, not from the grape itself.
Where can I taste this style in Sonoma County?
Dry Creek Valley is the traditional home of Zinfandel rosé in Sonoma, anchored by Pedroncelli. Halleck Vineyard in Sebastopol, Truett-Hurst in Healdsburg, and St. Francis Winery in Sonoma Valley each pour their own version, though most producers make a dry style rather than the sweeter grocery-store wine.
What food pairs well with White Zinfandel?
A dry Sonoma-style rosé of Zinfandel pairs well with grilled chicken, charcuterie, salmon, and dishes with real spice. The sweeter, mass-market style is traditionally served with Tex-Mex or barbecue, where the residual sugar tempers the heat instead of clashing with it.
Why did some Sonoma wineries stop calling it White Zinfandel?
Because the name became shorthand for a cheap, overly sweet style, and it stopped describing what serious producers were actually making. Pedroncelli renamed its wine from Zinfandel Rosé to Dry Rosé of Zinfandel around 2007 specifically to separate its bone-dry style from that reputation.
