26 October 2023 | nicolas In 2013, ALTER OAK designed the first range of natural 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. ALTER OAK also registered 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.
