Our values

For generations, we have upheld a core principle: every oak tree we purchase must be fully valorized. This respect for the raw material guides all our activities — from sustainable forest selection to transformation — and shapes every stage of the oak’s lifecycle.

With the expertise of our houses, each selected oak is processed according to the highest standards of quality, traceability, and sustainability.

This noble, enduring material is transformed into premium lumber, fine wood products, and exceptional staves for our cooperages — guardians of the barrel-making tradition.

Extending the lifespan of oak barrels is a natural extension of this approach. It reflects our multigenerational expertise, a strong sense of responsibility, and a pragmatic, forward-looking vision of resource management.

As high-quality oak becomes increasingly scarce, we have structured our operations to optimize each cask: inspection, repair, reconditioning, and recycling — every action is designed to extend its use while maintaining its technical and sensory performance, reducing reliance on fresh wood.

This circular model is deeply rooted in our culture. It is a practical, long-term commitment to sustainability — in service of the forest, our industry, and future generations.

Natural

The stave wood is naturally air-seasoned in pollution-free outdoor yards for a minimum of 6 months, ensuring ideal maturation conditions.

Barrel Production & Quality Commitment

At our cooperages, every barrel undergoes strict quality controls at each critical stage of production.

The origin and composition of the oak used are recorded, and the entire manufacturing process — including the toasting method — is fully documented.

These rigorous steps ensure maximum consistency, traceability, and reproductibility, in line with the expectations of the most demanding distillers.
