Why it matters: - Premium wineries are looking for closures that protect wine quality without giving up traditional cork presentation. - Collection by DIAM is designed to combine those goals in one closure for North American wineries. - The product is aimed at controlling oxygen transfer, supporting aging performance and reducing cork-taint risk.
