From Hermitage to Fully: Caroline Frey Comes Home to the Mountains
For twenty years, Caroline Frey ran three of France's greatest estates — Château La Lagune, Paul Jaboulet Aîné and Château Corton C — and became a world reference for biodynamic viticulture. Then she gave it all up for less than a hectare of vines in the Valais, the place she fell in love with through a glass of Petite Arvine. In 2025, taking over the legendary Cave Benoît Dorsaz, her mountain estate reached six hectares. Her verdict: «It's not an end, it's a continuation.»
Caroline Frey was born in Champagne, the daughter of Jean-Jacques Frey, founder of the family group — and she grew up in the vineyards her family was acquiring, choosing a scientific path that led to an honours degree in oenology at the University of Bordeaux, alongside her mentor Denis Dubourdieu. It was there, twenty years ago, that the future turned: tasting a Petite Arvine of Marie-Thérèse Chappaz while still an intern, she was shocked by the grape's brilliance — and Dubourdieu, who regarded it as one of the greatest white varieties in the world, sealed her conviction.
The years that followed made her famous. In 1999 she took over Château La Lagune in Bordeaux, adding Paul Jaboulet Aîné in the Rhône in 2006, then Château Corton C in Burgundy — running three of France's most prestigious estates for two decades and becoming a recognized ambassador of biodynamic viticulture, certified first at La Lagune in 2016, then at Jaboulet and Corton. All the while, Switzerland was calling: Swiss by nationality through her paternal grandfather, with family roots in the Aosta Valley and a climber's love of the Alps, she planted her first Valais vines in 2016 — fewer than 5,000 square meters, on the terraces of Fully. She also found a winemaker's house at Grandvaux, on the shores of Lavaux, where the cuvée Le Lac was born from the parcel at the foot of the house.
The Place — The Dorsaz Terraces of Fully
In the spring of 2025, Caroline took over the Cave Benoît Dorsaz — marking her tenth harvest in the region and the culmination of a path many had seen taking shape. The estate carries four generations of the Dorsaz family: an exceptional viticultural heritage, recognized for its precision, authenticity and deep respect for nature, built on small mountain terraces above Fully, near Sion.
Small Mountain Terraces
The production of the six-hectare estate remains deliberately limited, each parcel allowed to express the true character and purity of its alpine terroir. On his retirement, Benoît Dorsaz wished to entrust his vineyard to a winemaker who shared his philosophy — so its spirit would endure with the same integrity.
Biodynamics as Inheritance
Dorsaz was a pioneer of biodynamics in the Valais; Frey was its ambassador in France. The handover joined two biodynamic lineages on the same terraces — farmed to a Demeter-level standard, certified Bio Suisse.
Indigenous Grapes First
Petite Arvine is the muse — the grape her mentor called one of the world's greatest whites — with Chasselas and Johannisberg completing the alpine palette. Capricious varieties, demanding viticulture: exactly the challenge she crossed the country for.
A Foot in Lavaux
At Grandvaux, her winemaker's house holds a parcel at its foot — the source of Le Lac, looking over the waters of Lake Léman: a second terroir, gentler and lacustrine, to set against Fully's vertigo.
Winemaking — Exigence, at Mountain Scale
The method is the one she refined across three great French estates, now applied to alpine fruit. A demanding, inspiring viticulture where every gesture matters, where nature reigns supreme and time retains its true meaning — the words she uses for Fully could be her entire philosophy. The wines are precise, alpine, reflections of an exacting and biodynamic agriculture.
The Petite Arvine expresses itself here with all its saline tension and mineral energy — the very qualities that shocked her in Chappaz's glass twenty years ago. The labels pay homage to the Swiss mountains, rendered in clean lines under the cuvée names: vertigo bottled.
She is also a member of mémoire.wine, the collective dedicated to the memory and identity of Swiss wine terroirs. After a health episode forced an abrupt break, she re-examined her choices, her balance, her priorities — and chose the mountains. Her family continues the French chapter: her father Jean-Jacques's vision as foundation, her sister Delphine carrying the soul of the family estates.
The Wines — Alpine Precision, Mountain Labels
A deliberately small range of alpine wines — each label a drawing of the Swiss mountains, each wine a statement of place. Volumes are limited; the waiting lists are not.
Petite Arvine
The muse — saline tension and mineral energyThe grape that brought her to the Valais, farmed biodynamically on the Fully terraces. Citrus and white flowers over a frame of salt and stone — the cuvée that carries her mentor's prophecy.
Les Grains Blancs
The blend — Chasselas & JohannisbergA fine, elegant blend of Chasselas and Johannisberg — white flowers, curry and fermented pear on a discreet nose, tension on the palate: the everyday alpine white elevated by grand-cuvée care.
Le Lac
The Lavaux chapter — Grandvaux, at the foot of the houseFrom the parcel at the foot of her winemaker's house in Grandvaux, above the waters of Lake Léman: a gentler, lacustrine counterpoint to Fully's mountain terraces, named for the lake it overlooks.
The French Chapter
La Lagune, Jaboulet, Corton C — the estates she left behindChâteau La Lagune, Paul Jaboulet Aîné, Château Corton C — and the 2023 Domaine de La Chapelle with its emblematic Hermitage La Chapelle and Le Chevalier de Sterimberg: two decades of biodynamic conversion and world-class wine, now continued by her family while she writes the Swiss chapter herself.
Legacy — The Star Who Chose the Slope
Caroline Frey's first legacy is French — and finished. Twenty years of passionate commitment to Château La Lagune, Paul Jaboulet Aîné, La Chapelle Hermitage and Domaine Caroline Frey, with organic then biodynamic certification across all three estates — a body of work that made her, at 47, one of the most respected oenologists in the world. A difficult health moment forced the abrupt break; the family group continues under her father Jean-Jacques's foundation and her sister Delphine's direction.
The second legacy is the homecoming. From fewer than 5,000 square meters in 2016 to six hectares in 2025, she rebuilt her life at mountain scale in the Valais — joining the Paulée de Fully, joining mémoire.wine, taking the Dorsaz terraces into their fifth generation. As the Swiss retailer Karafe puts it: this is not a star buying herself a vine — it is an exceptional winemaker returning to the earth, in a human-scale project that speaks to her.
And the legacy is a door held open. When a winemaker of her stature chooses the Valais — and says so, bottle after bottle — she redefines what the canton's terraces can be. «It's not an end, it's a continuation»: the continuation of a biodynamic lineage, from Bordeaux to the mountains that were calling all along.
