Champagne Is From France
From three years as assistant winemaker at Schramsberg to a Napa garage and now a global sparkling phenomenon, Dan and Jacqueline Person are proving that California bubbles don't need to taste like brioche and butterscotch. They need to taste like California — sunshine, mango, and the Pacific breeze, sealed with a crown cap.
From Pre-Med to DRC
Dan Person was a pre-med student before a "flash-forward" moment made him question whether he would actually enjoy his quality of life as a doctor. He decided to come to California, got a job in the laboratory at a large winery, worked there for a year and a half, then enrolled at UC Davis to study the science of winemaking [^148^].
From Davis, he worked in France at Domaine de la Romanée-Conti — a snapshot of Burgundian winemaking that would shape his understanding of terroir, though he would "certainly take away different lessons today than he did then" [^148^]. He then spent three years as assistant winemaker at Schramsberg, Napa's most prestigious traditional sparkling house, where he made 85,000 cases of Champagne-method wine annually [^146^][^148^].
Jacqueline Person was simultaneously making still wines from a variety of terroirs across California — experiences that would later inspire the vineyard selections for Carboniste [^148^]. They met at UC Davis, fell in love, and started their label in 2017 with a shared frustration: "All of the commercially relevant domestic sparklings are basically an homage to Champagne. Everyone is trying to replicate France in California" [^146^].
Dan's epiphany came while tasting California sparkling wines aged for 18, 36, or 60 months on lees. "You go from this nice, bright orange, like mandarin orange, to marmalade, to marmalade and caramel. And it's just too much." The fruit was already sweet from California sunshine; adding yeast-derived brioche and butterscotch created a cloying combination. "Why would you want mango with butterscotch? It doesn't sound good" [^148^].
"Champagne is from France. Carboniste is California."

Three Months, Crown Caps, Terroir First
Carboniste's radical simplicity is threefold: shorten the en tirage aging, use crown caps instead of corks, and let California fruit speak for itself. In Champagne, the legal minimum is 12 months on lees; Carboniste ages for just three. "I don't want it to taste like yeast. I want it to taste like the grapes. I want it to be about the varietal" [^148^].
The crown cap is not a cost-cutting measure — it is a functional and philosophical choice. "It may seem like a cheap-looking thing to put on the wine. Champagne has to have a cork in it legally... but almost every single bottle of wine in Champagne, in their cellars, is closed with a crown cap." The cork is aesthetics only; the crown cap is superior — easier to handle, better closure, zero TCA taint [^148^].
The goal is transparency: "a wine that's transparent, that really shows to the consumer what that vineyard is about and what these grapes can do in California." No mango with butterscotch. No marmalade with caramel. Just sunshine, acid, and the specific character of each site — whether that's the Sacramento Delta's Albariño, Corralitos' Pinot Noir, or Marin's cold-climate Chardonnay [^148^].
3 months on lees for the Critter Series, 9 months for single-vineyard wines. No yeast-derived brioche, butterscotch, or caramel. The fruit is front and center — bright, fresh, and unmistakably Californian.
Superior closure to cork — no TCA taint, easier to handle, better seal. Used throughout Champagne cellars before disgorging. Carboniste simply skips the aesthetic cork and keeps the functional cap. Modern, honest, practical.
Each wine is handled differently depending on the fruit. Not méthode traditionnelle, not pét-nat, not ancestrale — a flexible, modern approach that serves the vineyard. The goal is to show what California grapes can do, not what France does.
Extra Brut across the range. Minimal sugar added at disgorging. The natural sweetness of California fruit provides balance without masking acidity. Clean, crisp, refreshing — never cloying.
From the Delta to the Santa Cruz Mountains
Dan's search for fruit took him beyond the traditional sparkling wine sources. He found Albariño from the Gomes family in the Sacramento Delta — one of California's oldest farming families, Portuguese immigrants who have worked Andrus Island since the 1800s. Their vineyard has deep, rich soil fed by the Sacramento River, dry-farmed, transitioning to organic certification [^152^].
Then came Corralitos in the Santa Cruz Mountains — a site Dan had never heard of as a Napa native. Craig and Cathy Handley of Pleasant Valley Vineyards hired him to make sparkling from their fruit, and he was stunned by the quality: "I picked it early and it's better than Carneros." The Pinot Noir from Corralitos is red-fruited, strawberry and raspberry, with vibrant acid — "I have never found Pinot Noir that is so expressive at sparkling levels of ripeness. The wind and sandy soil are factors, for sure" [^146^].
The single-vineyard program expanded to include Frances J Vineyard (formerly Pleasant Valley, now owned by Frances McIntyre), Lester Family Vineyards in Corralitos, Deer Park Ranch, and organically grown sites in Marin County — where cold weather, disease, shallow soil, and lack of water make viticulture "not for the faint of heart" [^146^][^148^].
The Corralitos Brut
A classic Brut, 50/50 Pinot Noir and Chardonnay, from three Corralitos vineyards. The Chardonnay from Frances J is "natural and savory, like roasted almonds. It's not oxidized, but comes across as rich even when young." The Pinot Noir from Lester brings strawberry, raspberry, and vibrant acid. Nine months in barrel, nine months on lees in bottle, nine months after disgorging — a 27-month journey that balances Pinot and Chardonnay's need for time with Carboniste's freshness-first philosophy [^146^][^148^].
Octopus, Sea Urchin, & Playful Bubbles
Carboniste's entry-level wines are called the "Critter Series" — each named after a sea creature that reflects the wine's coastal roots and pairing potential. The Octopus Sparkling Albariño was the first, chosen because it is "playful, fun, and bubbly" — and because Albariño's crisp acidity and minerality make it a perfect match for grilled octopus [^152^].
The Sea Urchin Sparkling Rosé follows the same logic: wild strawberry, cherry, guava, bright acidity, and a clean crisp finish that pairs with fresh seafood including uni (sea urchin) [^157^]. These are not serious, contemplative wines — they are "happy, bright, colorful wines that you could drink really without thinking." The rosé is meant to be "crushable, rosé-all-day" [^148^].
The Pinot Grigio Pét-Nat Extra Brut is the most experimental Critter — bottled during primary fermentation, capturing the early essence of the wine, then disgorged to clean up sediment. "It's still the essence of Pét-Nat, but it's not dirty or mucky. We didn't want to make an unsophisticated, rustic product. We were aiming for something a bit more polished" [^148^].
"A product of much inspiration but not imitation, this brand has been born out of our love of sparkling wine."

The Carboniste Universe
All wines are made via méthode traditionnelle (with variations), hand-harvested, fermented with indigenous and commercial yeasts, and bottled with minimal dosage (Extra Brut). The Critter Series offers accessible, playful entry points; the Single-Vineyard Series elevates specific terroirs with longer aging and more complex structure. Every wine is sealed with a crown cap — no corks, no cages, no ceremony. Just pop and pour [^144^][^148^][^151^].
