The Dreamer's Hand & the Alluvium of Bennwihr
Emmanuelle Milan & Mathieu Deiss are one of the most exciting young couples in natural wine — a union of two of France's most distinguished viticultural dynasties, producing boundary-pushing biodynamic wines in the village of Bennwihr, just outside the Kaysersberg valley in Alsace. Mathieu is the son of Jean-Michel Deiss and grandson of Marcel Deiss of the legendary Domaine Marcel Deiss in Bergheim; Emmanuelle is the daughter of Henri Milan, the pioneering natural winemaker of Domaine Milan in Saint-Rémy-de-Provence. Together, since 2013, they have transformed 7 hectares of inherited vines — bequeathed by Mathieu's maternal uncle — into Vignoble du Rêveur, a domaine devoted to texture, consistency, depth, and minerality over grape variety. Their wines — from the crystalline Riesling Vibrations to the amber amphora-aged Un Instant sur Terre and the revolutionary Rien ne Bouge — are made with indigenous yeasts, long macerations, amphora élevage, and zero or minimal sulphur. In a region often constrained by convention, Emmanuelle and Mathieu are dreamers in the truest sense — proving that Alsace is a playground for the imagination.
The Deiss Dynasty & the Milan Legacy
The story of Vignoble du Rêveur begins with two extraordinary family histories. Mathieu Deiss was born into Alsatian wine royalty — the Domaine Marcel Deiss in Bergheim, founded by his grandfather in 1947 and elevated by his father Jean-Michel into one of the most intellectually rigorous and sought-after estates in France. From an early age, Mathieu absorbed the Deiss philosophy: terroir over grape variety, complantation over monoculture, and the relentless pursuit of mineral expression. He continues to work alongside his father at the family domaine, but the call of his own path was irresistible.
Emmanuelle Milan grew up in the sun-baked hills of Saint-Rémy-de-Provence, where her father Henri Milan — a friend of Claude Courtois and a disciple of biodynamic pioneer Claude Bourguignon — had transformed Domaine Milan into one of the most important natural wine estates in the south of France. Henri was sulphite-free from 2000, a radical stance in Provence, and Emmanuelle learned to see wine not as a product but as a living expression of soil, sun, and soul. She trained as an oenologue and brought her father's fierce independence to Alsace.
The couple's paths converged in 2011, when Mathieu's maternal uncle, Cassien Mischler, fell ill and could no longer tend his 7-hectare vineyard in Bennwihr. Rather than let the vines fall into neglect, Mathieu and Emmanuelle took over, converting the estate — already organically farmed — to biodynamics and achieving Demeter certification in 2013. They named it Vignoble du Rêveur — The Dreamer's Vineyard — in tribute to Mathieu's grandfather and his lifelong fight for independence. "All his life, our grandfather fought for his independence, his only true freedom," they write. "Serving this vineyard is today a tribute to this struggle, to this ideal, and an extension of his Dream."
"Refound this dream, rebuild a future without restrictions, reinvent the wine to its definition, break the codes, spread the walls and open your eyes, to say that anything is possible!"

Bennwihr & the Quaternary Alluvium
Vignoble du Rêveur is located in Bennwihr, a small village just north of Colmar, on the edge of the Kaysersberg valley — one of the most picturesque and viticulturally significant corridors of Alsace. The estate comprises 7 hectares of contiguous vines, all rooted in a single, remarkable terroir: quaternary alluvium — a thick layer of recent glacial deposits from the Würm period (between -130,000 and -10,000 years), covering older sedimentary strata from the Oligocene and Pliocene epochs. This geological history — shaped by the collapse of the Rhine basin, the intrusion of a prehistoric sea, and the subsequent uplift of the Vosges — has created a soil of exceptional complexity and freshness.
The alluvial soils are rich in pebbles and gravel, providing excellent drainage and forcing the vines to send roots deep into the fractured subsoil. The result is a marked saline, mineral character in the wines — a freshness and tension that belie the warm Alsatian sun. The vines are 40 to 50 years old, planted to a complanted mix of Riesling, Pinot Gris, Pinot Noir, Pinot Blanc, Gewürztraminer, and Muscat, and pruned in Guyot Poussard to respect the sap flow and maintain vine health. No chemical treatments have ever touched these parcels, and none ever will.
The Bennwihr terroir is not a Grand Cru, but it possesses a character that Emmanuelle and Mathieu find liberating. Free from the pressure of appellation prestige, they can experiment, blend, macerate, and dream without the constraints of AOC conformity. The vineyard sits in the heart of the Rhine rift valley, where the Vosges mountains to the west and the Black Forest to the east create a unique microclimate of warm days and cool nights — ideal for preserving acidity while achieving full phenolic ripeness. The result is fruit of extraordinary aromatic intensity and mineral backbone — the raw material for wines that are as intellectually engaging as they are pleasurable.
Bennwihr is a quiet village in the Haut-Rhin, overshadowed by its more famous neighbours Kaysersberg and Riquewihr, but possessed of a terroir that is uniquely suited to natural viticulture. The quaternary alluvium — a mix of glacial gravel, sand, and clay — provides both drainage and mineral richness, while the flat-to-gently-rolling topography allows for consistent sun exposure. The village sits at the confluence of ancient geological forces, and the wines reflect that complexity: saline, fresh, and deeply rooted in the earth. For Emmanuelle and Mathieu, Bennwihr is not a second-choice site; it is a blank canvas.
The soil of Vignoble du Rêveur is a geological poem written over millions of years. The surface layer — alluvium from the last glacial period — is a matrix of pebbles, gravel, and sand deposited by ancient rivers and glaciers. Beneath this lies the Oligocene sedimentary rock, formed when a prehistoric sea filled the Rhine basin, and the Pliocene fluvial deposits laid down when the Rhine itself carved its path through the valley. This layered history gives the wines their distinctive mineral signature: a chalky, saline freshness that runs through every cuvée like a thread. The alluvium forces the vines to struggle, producing small berries of intense concentration and aromatic purity.
Following the Deiss family tradition, the vineyard is planted in complantation — multiple varieties mixed together in the same parcel, harvested and often vinified together. This ancient practice, abandoned by most of Alsace in favour of monoculture, creates a natural balance in the vineyard: early and late ripeners, deep and shallow rooters, aromatic and structural varieties all coexist, supporting each other's health and complexity. The vines are pruned in Guyot Poussard, a method that respects the sap flow and reduces the risk of vine disease. The result is a vineyard that functions as a self-sustaining ecosystem, requiring minimal intervention and producing grapes of extraordinary vitality.
The estate has been farmed according to biodynamic principles since Mathieu and Emmanuelle took over, achieving Demeter certification in 2013. The biodynamic preparations — horn manure, horn silica, compost teas, and herbal preparations — are applied according to the lunar calendar, and the vineyard is treated as a living organism rather than a production unit. No synthetic chemicals, herbicides, pesticides, or chemical fertilisers have ever been used on these parcels. The goal is not merely to produce grapes, but to regenerate the soil, increase biodiversity, and create a self-sustaining agricultural ecosystem that will endure for generations. The health of the vines is evident in the wines: transparent, alive, and profoundly expressive of their terroir.
Texture & the Amphora Hand
The cellar philosophy of Vignoble du Rêveur is distilled in a single sentence: "We have chosen not to put forward any particular grape, but rather the texture, consistency, depth, and minerality of the wine." This is the Deiss family credo, inherited from Marcel and Jean-Michel, but Emmanuelle and Mathieu have pushed it into new territory. Their tools are indigenous yeasts, long macerations, amphora ageing, and an absolute refusal of additives. Sulphur is used sparingly if at all — many cuvées are bottled with zero added sulphites.
The estate produces a dazzling range of styles from the same vineyard. Direct-pressed whites — like Vibrations — are fermented and aged in large foudres on their lees for a year, producing wines of crystalline purity and saline tension. Skin-contact orange wines — like Artisan and Un Instant sur Terre — undergo macerations ranging from 10 days to 8 months, often in clay and sandstone amphoras, producing wines of extraordinary texture, amber hue, and complex aromatic depth. Rien ne Bouge — perhaps their most revolutionary cuvée — is made by macerating whole bunches of Pinot Noir in direct-pressed white grape juice, creating a wine that blurs the line between red and white, between Alsace and the Jura.
All fermentations are spontaneous, driven by the indigenous yeasts of the vineyard and cellar. There is no chaptalisation, no acidification, no selected yeast, no enzymes, and no filtration for most cuvées. The wines are aged in a combination of stainless steel tanks, large wooden foudres, and amphoras — each vessel chosen to suit the specific wine and vintage. The result is a portfolio of extraordinary diversity and coherence: wines that share a common mineral thread but express it through radically different textures and colours. Emmanuelle and Mathieu see these methods not as ends in themselves, but as tools in service of the wine — a means to reveal the full potential of their alluvial terroir.
Indigenous Yeasts, Amphora & the Texture Ethos
The guiding principle of Vignoble du Rêveur is that the vineyard speaks, and the cellar's job is to translate. The biodynamic farming provides healthy, complex grapes. The hand harvest provides pristine fruit. The complantation provides a natural balance of sugars, acids, and aromatics. The indigenous yeasts provide spontaneous, site-specific character. The long macerations — whether 10 days in stainless steel or 8 months in amphora — extract the full phenolic and aromatic potential of the skins. The amphoras provide a neutral, breathable home that respects the fruit without masking it. And the minimal or zero sulphur provides wines that are alive, transparent, and deeply expressive of their Bennwihr terroir. The cellar is a laboratory of patience; the wine is its honest report.
Vibrations, Un Instant sur Terre & the Rien ne Bouge Revolution
Vignoble du Rêveur produces approximately 60,000 bottles per year across a diverse, imaginative portfolio that spans direct-pressed whites, skin-contact orange wines, experimental reds, and traditional-method sparkling. Each cuvée is named to evoke an emotion, a sensation, or a state of mind — reflecting the estate's belief that wine is not merely a beverage but an experience. The wines are bottled with glass stoppers for many cuvées, preserving their vitality and allowing for resealing. All are made with indigenous yeasts, minimal or zero sulphur, and no filtration — a guarantee of absolute natural integrity.
The Dreamer's Vineyard & the Future of Natural Alsace
Emmanuelle Milan and Mathieu Deiss are not merely making wine; they are bridging two of France's greatest viticultural traditions and forging a new path that belongs entirely to them. From the Deiss family, they inherited the intellectual rigour of complantation, the obsession with terroir, and the refusal to accept that grape variety matters more than place. From the Milan family, they inherited the courage to go sulphite-free, the commitment to biodynamics, and the belief that wine should be alive, joyful, and free from convention. Together, they have created something that is greater than the sum of its lineages — a vineyard where the dream is not just preserved but constantly reinvented.
The legacy of Vignoble du Rêveur is the legacy of two young people who looked at 7 hectares of inherited vines and saw not a burden, but a canvas. They have proven that Bennwihr — a village without Grand Cru status — can produce wines of extraordinary complexity and originality. They have shown that 8-month amphora maceration, carbonic maceration of white grapes, and red-white blends are not eccentricities but legitimate expressions of terroir. And they have demonstrated that the children of two great families can honour their parents while building something entirely their own.
The future is one of deepening and expansion. As the 40–50-year-old vines of Bennwihr accumulate another year of biodynamic wisdom, as the amphora collection grows, and as new cuvées emerge from the cellar, Vignoble du Rêveur remains what it has always intended to be: a place where anything is possible, where the walls are spread open, and where the eyes are wide. The story of Emmanuelle Milan and Mathieu Deiss is the story of a couple who inherited the dreams of their grandfathers and decided not just to continue them, but to dream bigger — and who proved that the best bottle from Alsace is the one that makes you believe, if only for an instant, that you too are a dreamer.
"The Dreamer is barely dozing, the dream is just beginning, so many things to test yet, to rediscover."
