Adrien de MelloFrom Brittany to Layon
From geography student to Quebec grape picker, from Châteauneuf-du-Pape to Anjou—founding Domaine de la Petite Sœur in 2015, named after his daughter Louise, farming 4 hectares of schist with horse Toscane, Demeter certified, zero additives.
From Quebec to Layon—how a Breton geography student became a biodynamic vigneron named after his daughter.
Adrien de Mello is originally from Brittany. He initially studied geography, but "all things considered, it wasn't really his thing." In 2003, he preferred to fly free as a bird to Quebec. There, he found a job as a grape picker for a wine estate—a "seasonal" job that would ultimately last 3 years [^273^].
Young, ultra-dynamic, and above all self-taught, Adrien threw himself into the work. In Quebec, he developed a passion for biodynamics, which he first discovered through books. His mother was a librarian—she sent him specialized books from France that were impossible to find in Quebec. This autodidactic approach to natural wine would define his future path [^273^].
Due to a family event, he had to return to France in 2010. He vinified for several years in Châteauneuf-du-Pape for a biodynamic estate run by Bernard Duseigneur. Then a happy event precipitated his departure—his partner had a son from a previous marriage, Oscar, who was in shared custody between Brittany and the South of France. The endless and tiring back-and-forth could no longer continue: Adrien was going to become a father to a little girl named Louise. Hence the name of the Domaine de la Petite Sœur [^273^].
He chose Anjou as his playground, specifically Saint-Aubin-de-Luigné. He had the opportunity to set up in the superb cellar of the Château de Genaiserie and take over vines on schist terroir from Thomas Carsin (3.5 ha), already cultivated organically. Adrien went further, applying biodynamic principles and working his soils with a horse, with whom he formed a special bond [^273^][^278^].
"Essence and substance"—zero additives, zero filtration, wild plant teas, and the blood of the vine.
Adrien's philosophy is one of radical transparency and deep respect for the living ecosystem. Since taking over the vines, he has applied biodynamic principles with obsessive attention to detail. In just a few years, he gained both organic and Demeter biodynamic certification [^278^][^297^].
He plows by horse (his beloved horse Toscane, though he had to sell her during financial difficulties) and is passionate about foraging wild plants such as nettle, comfrey, yarrow, and buckthorn to prepare teas for use in the vineyards. His care and attention here produce wines with great clarity and a startling purity of fruit [^278^][^297^].
In the cellar, Adrien's work is defined by a lightness of touch. The motto is simple: in the cellar, only grapes go into the bottle—no additives, no filtration. "Essence and substance!!! Wine is the blood of the vine..." This commitment to zero intervention allows the schist terroir to express itself fully [^296^][^297^].
For reds, he works with whole bunches. For whites, Sauvignon Blanc undergoes 7-9 day maceration, while Chenin is directly pressed. Gentle extractions reveal just enough detail and nuance from the grapes, with a focus on expressing the perfume of each variety while harnessing the incredible character that schist brings [^296^][^278^].
Wild Plant Teas
Essence & Substance
The schists of Saint-Aubin-de-Luigné—black schist soils in the heart of Layon.
Hectares
4 hectares of vineyards planted over black schist in and around the village of Saint-Aubin-de-Luigné, in the heart of the Layon area of Anjou. The vines were already farmed organically when Adrien took over, but he has since elevated them to biodynamic certification [^278^][^285^].
Year Old Vines
Vines with an average age of around 40-50 years—deep-rooted plants that have taken hold in the schist subsoils. These old vines produce concentrated fruit with natural acidity and minerality from the schist terroir [^296^][^278^].
Black Schist
The terroir here is dominated by black schist—metamorphic rock that gives the wines their characteristic minerality, smoky notes, and fine tannins. Some parcels also contain clay. This unique geology defines the saline, flinty character of Petite Sœur wines [^285^][^278^].
From orange Sauvignon to whole-bunch Cabernet—fresh, fragrant, and invigorating expressions of Layon schist.
Les Gâts
A Sauvignon Blanc that breaks all the rules. From two distinct parcels—45-year-old vines over schist and 30-year-old vines over clay. This is an orange wine (vin orange) with a pale amber hue, offering an aromatic bouquet of tropical fruit, rose, and lychee. On the palate, it balances vibrant structure with exotic fruit notes. Short maceration of 7-9 days gives it texture without heaviness [^296^][^294^][^303^].
Globule Blanc / Chiferdeux / Les Justices
Chenin Blanc from 40-50 year old vines grown in schist. Directly pressed to preserve purity and freshness. Aged for a year in tank or barrel. Notes of baked apples, sea salt, and plenty of minerality. An easy-going Chenin with that characteristic golden hue in the glass—showing the saline, flinty side of schist-grown Chenin [^296^][^300^][^311^].
Sovaj
A white Sauvignon Blanc (not orange) showing the variety's ability to express terroir when farmed biodynamically. Fresh, citrusy, with the smoky minerality of schist. A vibrant, invigorating wine that demonstrates Adrien's ability to work with the same grape in different styles [^297^].
Globule Rouge
Cabernet Franc vinified with whole bunches—stems and all. This traditional method gives the wine structure, spice, and a vibrant aromatic profile. The schist terroir adds a smoky, mineral backbone to the red fruit. No additives, no filtration—just pure Cabernet Franc from 40+ year old vines [^296^].
Érogène
Cabernet Sauvignon from the schist soils of Saint-Aubin-de-Luigné. Despite Cabernet Sauvignon's reputation for heaviness, Adrien's light touch and whole-bunch approach create a wine of surprising elegance and perfume. The schist moderates the grape's natural power, resulting in a balanced, terroir-driven red [^296^][^284^].
Gamins
Gamay—the "kids" or "youngsters"—from old vines in Anjou. Light, fresh, and gulpable, this shows the lighter side of Adrien's range. Whole-bunch fermentation gives it that characteristic peppery, vibrant quality. Perfect for casual drinking but with the seriousness of schist terroir [^296^].
Plasma
A unique rosé blend of Cabernet Sauvignon and Sauvignon Blanc—red and white grapes together. Combining direct-press and maceration methods, this is a highly original take on rosé. Sourced from organic vines rooted in schist-rich soils across the 4-hectare vineyard. Light, fresh, with both red fruit and citrus notes [^276^][^310^].
Go Fast
A blend of Grenache and Cinsault—southern varieties that bring a different character to the schist terroir. Lighter, fruit-forward, and fun (hence the name), this shows Adrien's willingness to work with varieties beyond the typical Loire grapes. Vin de France classification [^297^].
The Survivor of Saint-Aubin
Adrien de Mello's story is one of perseverance against impossible odds. The years 2016, 2017, and 2019 brought catastrophic frost—70%, 80%, and 50% losses respectively. In 2019, he was on the verge of giving up, selling his beloved horse Toscane and equipment just to finance the bottling of his 2018 vintage. But this "mal pour un bien" (blessing in disguise) gave him the opportunity to finally show the world who he is and what he does [^273^].
His salvation in 2018 came not from chemicals but from Bourdaine—an acidic tree used in decoction that saved his vines from mildew when all his neighbors were affected. This inventiveness, this "work of precision with the minimum of intervention possible," defines his approach. Today, Domaine de la Petite Sœur stands as a beacon of biodynamic excellence in Anjou, producing wines of startling purity and schist-driven minerality that offer a "highly original expression of the part of Anjou he calls home" [^278^][^273^].
