We innovate to perpetuate the great history of wine

Passionate about the art and culture of wine, aware of the urgency of environmental and societal challenges, and convinced that enlightened innovation must serve the common good, we want to use our know-how and strengths to serve the sustainable development of the wine sector.

Caroline FORGUES - Responsable RSE

We have long been committed to the environment and are now firmly engaged towards energy transition! Reducing our direct greenhouse gas emissions by half means participating at our own level in the international objectives to combat climate change, but it also means preparing for a world where energy will be increasingly scarce and expensive.

CSR Manager

We aim to offer our customers both technically perfect products and the certainty of working with a responsible and committed supplier.

Our priority commitments

Would you like to recycle your corks?

Since 2019, Diam Bouchage has been a partner of the Comité Interprofessionnel du Vin de Champagne (CIVC) and the Epsyvin association for the collection and recycling of used corks in the Champagne-Ardenne region. In 2020, we provided our customers in the Champagne region with collection points for corks. The corks are then grouped together at our Cumières plant before being sent for recycling. A similar initiative has also been set up in Gironde with our partner Agir Cancer Gironde, in 2021.
