The cork closure
to suit your needs

Range of still wines

More than just an ordinary closure, the Diam cork is a genuine oenological tool for winemakers, who can now choose the right amount of oxygen for the aromatic profile of their wine and the desired ageing time.

An essential for still wines

Our Diam range offers an unrivalled closure solution. The consistent mechanical properties of our corks, as well as a precise oxygen supply, give you the guarantee of a consistent aging from one bottle to another.

Although winemakers all over the world, in their great diversity, work with different terroirs, they all have the same basic requirements for which Diam has a proven track record: closure consistency, preservation of aromas, freshness for their wine without any sensorial deviation.

From Diam 2 to Diam 30, choose the cork which best corresponds to your still wine.
