In 2006 we registered the patent for the BARENA process to naturally regenerate casks & barrels. Shortly afterwards, our BARENA process was awarded the Innovation Trophy. Unique to France, this Oenovation® Trophy encourages innovation by entrepreneurs who invent and undertake to disrupt existing technologies. The selection is made on the basis of four criteria: economic potential, innovation potential, the quality of the project team, and the product's contribution to the wine and spirits industry.

At VINITECH 2008, our BARENA process won first prize in the international innovation trophy category. Indeed, this trade show, which brings together nearly 45,000 professionals, rewards innovation in the wine and spirits sector. More than just a reward, this trophy, reserved for equipment, process or technical suppliers, is a true recognition of the profession.

In 2013, ALTER OAK designed the first range of oak extracts. In response to the growing needs of our customers, we have created a range of products to refine the taste of your beers, wines and spirits. A range that we continually improve and modify.

In 2017, ALTEROAK registers a new patent: CARACTERE DUO. This new product, reserved for wines, uses the latest technological innovations in oenology. Indeed, thanks to our innovation our customers are now able to improve the structure, stability and longevity of their wine. Thanks to CARACTERE DUO let's improve your wines and make them change category.

In 2019, after many years of experimentation, ALTEROAK registered a patent for cask & barrel toasting. BARENA "tech-oenology" consists of toasting oak casks & barrels through the bung hole, without opening the ends. This revolutionary technique allows us to be more efficient and to respond in the best possible way to customer needs.
