As a leading innovator in developing effective wine closure solutions, OENEO Bouchage collaborates with some of the world's great viticultural institutions in both research and product development.

OENEO provides a secure closure with huge performance benefits, allowing our clients to close their wines with confidence. We have concentrated our efforts on two real threats to the wine industry: closure consistency with adapted OTR (Oxygen Transfer Ratio) and absence of released TCA.

We provide our clients an innovative and safe solution for their wines by offering DIAM, a technological cork free of TCA taint, for still and sparkling wine corks as well as a DIAM-based bartop for liquor and spirits. This closure offers flexibility, consistency and security to the winemaker, providing closures that suits differing winemaking styles and market requirements.
