The finest oaks for the finest staves. In 1928, drawing on eight generations of experience in the forest, Eugène Charlois founded Maison Charlois in Murlin. From forestry and oak selection to splitting and stave seasoning, the company perpetuates craftsmanship passed down over time. A profound expertise in the material, expressed in the quality of its staves, sourced from the finest French forests.

Located in the heart of an exceptional forest region, Les Ateliers du Chêne – Bourgogne carry out the primary transformation of oak. From structural and construction timber to joinery wood, from railway sleepers to staves, the site brings together the essential expertise required to enhance the material. A deep knowledge of oak, precise process control, and respect for the long-term perspective enable the teams to shape a demanding material — the foundation of durable, high-quality creations.

Atelier Ermitage develops a bespoke approach based on staves selected from the finest French state forests. Each barrel is conceived as a singular piece, where forest origin, oak maturation, and toast profiles are adjusted with precision.

For every project, the Atelier provides personalized support — from the selection of the raw material through to final delivery.

Located in northern Romania, in the Maramureș region of Transylvania, Transilvania Bois operates at the heart of the Carpathian Mountains, within exceptional forest territories. Its activities cover the entire oak value chain — forestry, sawmilling, parquet flooring, and stave milling. The oaks are selected from Romania’s three major historic regions — Transylvania, Moldavia, and Wallachia — whose forests are renowned for the quality of their stands. These origins give the oak an extra-fine to medium grain.

Les Ateliers du Chêne – Sud transform oak into fully realized creations. The site is dedicated to the design and manufacture of finished products in solid oak, for both interior and exterior applications.

Located in Sighetu Marmației, in northern Romania within the Carpathian Mountains, Tonnellerie Vlad works with high-value oak sourced from Romania’s main forest regions. Selected and transformed into staves by Transilvania Bois, this oak ensures a fully controlled continuity from forest to barrel. The House is distinguished by its artisanal toasting over oak embers, carried out slowly and at low temperature, developing refined and well-balanced aromatic profiles — with subtle vanillin notes that are highly sought after.

Established in 1980 in Calistoga, north of Napa Valley in the heart of California’s Wine Country, Nadalié USA was founded under the name “Tonnellerie Française.” The first French cooperage to export the art of cooperage across the Atlantic, it brought barrel production closer to California’s great vineyards. To meet the expectations of its clients around the world, Nadalié USA now works with premium oak staves sourced from the United States, France, and Transylvania — combining diversity of origins with rigorous selection standards.

In the late 1960s, the rise of premium wines in California generated strong demand for French oak barrels.

Located in Scotland, Oakwood Cooperage was founded by Brent Bowie in 2018 and operates across two sites: Keith and Uddingston. The House specializes in the restoration of used barrels for whisky and in the international trading of second-hand casks (Bourbon, Sherry, Port, etc.). All these oak vessels thus enter a new life cycle, extending the virtuous circle of sustainable management. A single oak barrel can reach more than 100 years of age, having contributed first to the aging of a fine wine and later to spirits. Oakwood Cooperage joined Charlois in 2022 to strengthen its position in the international market for used casks dedicated to spirits.

Off the Beaten Beauty Path — Inspired by an idea, but above all by oak, the king of the forest, the La Chênaie teams explore its beauty secrets. Majestic and resilient, oak is renowned for its longevity and its ability to adapt to the elements as it moves through the seasons. After years of research, the scientists at Laboratoire Exact succeeded in isolating and patenting molecules with anti-aging and antioxidant properties. These unique active ingredients replicate for the skin the protective and regenerative qualities of oak, enabling the creation of skincare products in perfect harmony with nature. Since 2016, each La Chênaie product has embodied a promise: to enhance beauty over time.

Since the mid-17th century, local activities and traditions have firmly anchored Charlois in Murlin, at the heart of the Bertranges Forest. This strong territorial attachment has led the Company to develop several projects within this wooded village of the Nivernais region. Charlois notably created an exhibition space supported by the Charlois Fund for Art and the Forest, highlighting cultural heritage and contemporary creation. Several monumental works have been and will be installed in the heart of Murlin to enhance and strengthen the village’s attractiveness, in continuity with the Group’s initiatives for the municipality (undergrounding of power lines, new public lighting, restoration of the church’s stained-glass windows, etc.). These various projects are part of a broader approach to developing sylvotourism and œnotourism.

Acquired over time, 150 hectares of land, ponds, and forests now make up La Ferme des Bertranges. Deeply connected to the land and to living systems in all their forms, and attentive to climate change, La Ferme des Bertranges practices organic and sustainable agriculture that respects the environment in order to produce high-quality food for healthy nutrition. To further strengthen its commitment, it implements traditional agroforestry practices.
