Vibration & Limestone

Mathieu Huguet's connection to wine was sparked early — not by a family château, but by his great-grandfather, a cellar master for a well-known wine merchant on Bordeaux's historic Quai des Chartrons, once the epicenter of global wine trade in the 18th and 19th centuries. From those early family memories came an attachment not just to wine, but to the idea of old bottles, deep cellars, and what time could do to a good wine. He still recalls tasting extraordinarily old Bordeaux that lingered not just on the tongue but in memory. His father, too, was a wine lover, and this legacy took root — but Mathieu's approach was never nostalgic. He saw winemaking as a living craft that required constant engagement, experimentation, and adaptation.

Mathieu and Bénédicte met at university while studying biology, drawn not to viticulture at first but to the living systems that underpin all of it: soil, fermentation, balance, the life beneath and within a plant. Mathieu completed his enology degree in 2002; Bénédicte earned her Ph.D. in wine microbiology in 2006, followed by a practical enology degree in 2008. Their paths diverged and converged — Mathieu into consulting, Bénédicte into the polished cellars of Chanel's estates. For eight years, she directed viticulture and vinification at Rauzan-Ségla in Margaux and Château Canon in Saint-Émilion, guiding some of Bordeaux's most prestigious wines and garnering unexpected celebrity inside the appellation. Meanwhile, Mathieu became one of Bordeaux's most respected advisors on biodynamic and organic farming, guiding dozens of domaines through conversion.

The turning point came in 2012, when Mathieu met Jacques Fourès, founding member of the Mouvement d'Agriculture Bio Dynamique. "He introduced me to this profile of natural agriculture by clarifying my feelings on the ground and shaking up a large part of my certainties," Mathieu recalls. Since then, he learned to unlearn — to approach life and wine differently. Biodynamics became his hobby horse, applied both in his advice to other winegrowers and on his personal plots. The 2019 launch of Sadon Huguet was born of frustration: "We were upset by the Grand Crus only looking after architects. We wanted to speak about grape quality and sensitivity." They chose to rent rather than buy — avoiding land speculation in a region where prices spiral into the absurd — and to work with biodynamic growers who shared their vision.

The name "Sadon" is a reclaimed unit of measurement — once used to quantify the work of a vigneron and his ox in a single day, now repurposed to share their "jus de terroir." It is a Proustian madeleine for Mathieu, evoking mornings of harvest when grapes were still foot-trodden by hand, and the wonder of watching adults taste precious nectar from the barrel. The project is about doing wine differently — alternatively, rigorously, sensitively — as a place of expression, a reflection of a lifestyle turned toward nature and the ocean, seeking again those moments of fullness and adrenaline.

Mathieu Huguet describes his approach as "natural oenology" — a term that captures both the scientific rigor of his training and the radical minimalism of his practice. Biodynamic in the vineyard, no inputs in the cellar. No commercial yeasts, no enzymes, no additives, no fining, no filtration, no added sulfites. The cellar practices are humble and deeply manual, reflecting a philosophy of attention over control, of listening rather than imposing. Grapes are handpicked into baskets and pulled to the winery by horse on a sled — a striking juxtaposition in a region of châteaux and mechanized harvesters. Destemming happens by gravity and hand over a natural wicker-style screen. Fermentation unfolds in open 700-liter barrels, uncooled, with one gentle punchdown a day by hand. Pressing is done with a manual vertical press. The wine ages in 400L and 225L barrels, 15% new, from a small cooper named Montgillard. Three to four rackings occur before bottling.

The monitoring is constant — not by lab data but by taste. When reduction or oxidation arise, they respond with rackings or top-ups. Sulfites are avoided at all costs, but not ruled out entirely. "If we ever encountered a wine with mouse taint, we'd rather use a little sulfur than release something flawed. But we'd try everything else first." Their first line of defence against the mouse is to bury the wine as deeply into a reductive state as possible. This is not dogma; it is pragmatism guided by principle. The result is wines that are alive, authentic, and deeply connected to the limestone terroir — wines that carry the imprint of the soil, the season, and the hands that made them.

"Expression Calcaire 14" — The Limestone Red: The Expression Calcaire 14 is Sadon Huguet's flagship wine — a blend of 60% Cabernet Franc from the limestone-heavy section of Saint-Émilion and 40% Merlot from Blaye, grown an hour's drive northwest on what the Huguets describe as an identical geological setting. The "14" refers to the 14th century origins of the Sadon measurement unit, or possibly the specific parcel designation. It is a wine that challenges every preconception about Bordeaux: no château, no classification, no sulfites, no appellation — just limestone, grapes, and time. The 2019 vintage spent 18 months in barrel; the 2020, 20 months. Hand-harvested, co-fermented by feel and taste, not by rule. In the glass, it is deep ruby with garnet reflections. The nose offers intense blackberry, cassis, wild herbs, and a distinct mineral, chalky note. The palate is medium to full-bodied, with silky tannins, vibrant acidity, and a long, savory, saline finish — the limestone powder that Mathieu dreams of. It is a wine of vivid, angular, surprising life. Serve at 16–18°C. Ages 5–10 years. ~€20–€28 / ~$22–$30.

"Expression Calcaire 37" — The Cracked Stone: The Expression Calcaire 37 is the second cuvée in the limestone series — the number referring to a different parcel or soil expression within the same geological continuum. Where "14" captures the powdery, saline finesse of limestone, "37" evokes the cracked, fractured, more structured side of the same mother rock. The label illustration shows shattered stone — a visual metaphor for the wine's more angular, more tannic, more age-worthy character. Same blend (Cabernet Franc/Merlot), same method, different site. In the glass, it is deep ruby with purple reflections. The nose offers dark cherry, plum, graphite, and a smoky, earthy mineral note. The palate is full-bodied, with firm tannins, electric acidity, and a long, complex, savory finish. It is a wine for the cellar — structured, serious, profound. Serve at 16–18°C. Ages 10–15 years. ~€22–€30 / ~$24–$32.

"Expression Calcaire 62" — The Pebbled Shore: The Expression Calcaire 62 is the third expression — the number evoking the rounded pebbles and gravelly alluvium that characterize certain sections of the limestone plateau. The label shows smooth stones — a contrast to the shattered rock of "37" and the powder of "14." This cuvée captures the more generous, more approachable, more immediately pleasurable side of the same terroir. In the glass, it is ruby with garnet reflections. The nose offers red cherry, raspberry, violet, and a subtle mineral note. The palate is medium-bodied, with soft tannins, lively acidity, and a clean, refreshing, fruit-driven finish. It is a wine of joy and accessibility — the entry point to the Sadon Huguet world. Serve at 14–16°C. Drink within 3–5 years. ~€18–€24 / ~$20–$26.

"Expression Calcaire 8" — The Infinite Loop: The Expression Calcaire 8 is the most recent addition — the number 8 evoking infinity, cycles, and the endless return to the same limestone truth. The label shows stones arranged in a figure-eight, suggesting continuity, balance, and the eternal dialogue between vine and rock. This cuvée represents the Huguets' evolving understanding of their terroir — a synthesis of what they have learned from "14," "37," and "62." In the glass, it is deep ruby with luminous intensity. The nose offers complex dark fruit, wild herbs, and a profound mineral note. The palate is medium to full-bodied, with elegant tannins, vibrant acidity, and a long, layered, savory finish. It is a wine of maturity and integration — for those who have followed the Sadon Huguet journey from the beginning. Serve at 16–18°C. Ages 5–10 years. ~€20–€28 / ~$22–$30.

"Hybridis" — The Ziggy Stardust: The Hybridis is Bénédicte's most experimental, most boundary-pushing wine — a whole-cluster pressed Merlot matured in custom-designed concrete eggs and sandstone amphorae. "It's not red, not white, not rosé," she says. "It's its own planet. Like Ziggy Stardust." The wine floats between categories, expressing nuances that are unusual if not utterly unique — savory, mineral, floral, and deeply strange in the most beautiful way. The concrete eggs provide thermal stability and a unique micro-oxygenation; the sandstone amphorae add a kind of earthy, primal texture that is impossible to achieve in wood or steel. In the glass, it is copper-amber with hazy, luminous intensity. The nose offers dried rose, wild herbs, earth, and a distinct mineral, smoky note. The palate is medium-bodied, with gripping texture, vibrant acidity, and a long, savory, tannic finish. It is a wine for the adventurous — proof that even in Bordeaux, the most traditional of regions, there is room for something completely other. Serve at 10–12°C. Ages 3–7 years. ~€18–€26 / ~$20–$28.

"Sémillon" — The White: The Sémillon is Sadon Huguet's white wine — grown in Loupiac, Bordeaux, and vinified with the same zero-sulfur, natural philosophy as the reds. It is a vibrant wine with a slightly oxidative edge and a sharp mineral spine — the kind of white that belongs in tasting menus, not supermarket shelves. During a blending session in late 2024, visitors contributed their thoughts on the mix — a testament to the Huguets' collaborative, open approach. In the glass, it is golden yellow with a hint of amber. The nose offers ripe peach, citrus, hazelnut, and a distinct waxy, mineral note. The palate is medium to full-bodied, with creamy texture, vibrant acidity, and a long, savory, slightly oxidative finish. It is a wine of depth and character — white Bordeaux reimagined. Serve at 10–12°C. Ages 3–7 years. ~€18–€24 / ~$20–$26.

"Irouléguy" — The Basque: The Irouléguy is Sadon Huguet's Basque project — a wine from the mountain-framed appellation in southwestern France, where land prices are capped and community values enforced. Made from Petit Manseng and Petit Courbu, it applies the same biodynamic, zero-sulfur philosophy to a completely different terroir. The result is a wine of extraordinary aromatic intensity, mountain freshness, and a kind of wild, untamed energy that is distinct from the limestone elegance of Bordeaux. In the glass, it is pale gold with green reflections. The nose offers tropical fruit, white flowers, and a distinct mineral, herbal note. The palate is medium-bodied, with crisp acidity, a textured mouthfeel, and a long, refreshing, mineral finish. It is a wine of place and principle — proof that the method transcends the region. Serve at 10–12°C. Drink within 2–4 years. ~€16–€22 / ~$18–$24.

Vessels & Ageing: The Huguets work with a remarkable array of vessels, each chosen to serve the wine's natural expression rather than impose a house style. Open 700-liter barrels for fermentation — uncooled, with one gentle punchdown a day by hand. 400L and 225L barrels for ageing, 15% new, from cooper Montgillard — small enough for gentle micro-oxygenation, large enough to avoid dominant oak flavors. Concrete eggs for the Hybridis — thermal stability, unique texture, and a kind of pure, unadorned expression. Sandstone amphorae for the Hybridis — earthy, primal, and utterly distinctive. Manual vertical press for gentle extraction. Natural wicker-style screen for hand destemming. The common thread is the same radical simplicity that defines everything at Sadon Huguet: listen to the wine, respect its needs, and get out of the way. No fining, no filtration, no added sulfites. Just time, patience, and the living yeast.
