Our Heritage

With expertise passed from father to son, Tonnellerie de Mercurey combines over 25 years experience in the art of making barrels at a unique and innovative cooperage.


We have two passions:

1. Selecting the finest oak trees from the best forests in France.

2. Creating superior barrels using traditional cooperage methods combined with our signature blending techniques.


From forest to the glass, the Tonnellerie de Mercurey is the culmination of a long family tradition; and the personal passion of its owners, Carole and Nicolas TARTERET.

Tonnellerie de Mercurey; Precision in Blending Oak

The Tonnellerie de Mercurey is renowned for its precision in blending oak, using wood from three diï¬erent forests in every barrel. Our oak blending philosophy enables us to deliver barrels of the consistency and homogeneity our customers seek, year in, year out. The key to this consistency is our integrated stave-mill, NT Bois, which supplies all of our wood. From this relationship, we gain the unparalleled access, experience and knowledge of Nicolas Tarteret and his team of specialists.

Tonnellerie de Mercurey
Our state-of-the-art production facility, built to the specifications of winemaking premises was completed in 2009. Since that time we have continued to invest in technology and product stewardship to ensure our customers receive barrels of the finest quality. Working with respected industry laboratories, we regularly test our wood, air and water supplies to avoid any possible chemical contamination. Tonnellerie de Mercurey’s integrated NT Bois stave mill means that we can guarantee: • PEFC certified wood of French origin • Total traceability “from forest to barrel” ISO 9001 and ISO 22000 certifications guarantee the control, homogeneity, traceability and reproducibility of our manufacturing process and our quality of service.
The Oak Tree, Our Reason for Being
The Oak Tree, Our Reason for Being
Throughout the year, our timber specialists travel the length and breadth of France, using their unparalleled knowledge of terroir and forestry management to select only the finest oak trees from the best forests. Sourcing and blending oak from a select, but varied range of terroirs and forest types are the keys to the consistent quality of our barrels. From the forest to the stave mill and throughout the barrel-making process, the wood remains segregated in batches, guaranteeing the authenticity and traceability of our production.

Try our Chauffe Light Toast Series
23 September, 2019

CLL: CHAUFFE LIGHT & LONG  is delicately toasted over oak embers. The low temperature of the firing is off set by the length of toasting, which gives a honey colored profile with a depth of 3-5 mm. This very light toast has a minimal aromatic impact on the wine but adds a freshness and suppleness, which imparts to the wine brilliance and luminosity.

CL: CHAUFFE LIGHT This toast was born from a long aging experiment, conducted with historical Burgundy estates. The toasting process is identical to the CLL, but around half the time. This keeps the oak very fresh. This toasting must be used only for very high-quality grapes and is suitable for long aging processes, 18 months or more, to integrate the fresh oak. 

CLL +: CHAUFFE LIGHT LONG PLUS A light and long toast derived from our classic CLL toast; developed to get the very best out of the “Pierre” wood. In the CLL+ toast, we replace the last few minutes of low-temperature toasting with a rapid “coup de flame”. This allows us to take advantage of the natural richness of the Pierre wood while preserving its structure.
