Diam launches 100% bio-sourced ‘Origine’ cork

Tuesday March 14 2017 by Vitisphere

Diam has seen a constant increase in its market share in recent years: 10% of still wines using natural cork closures use Diam, compared with just 4% in 2006. On February 21, the company broke new ground again by presenting a 100% bio-sourced cork to the media.

“We have been working on this project for over 5 years”, explained Christophe Loisel, head of R&D at Diam. “We wanted to develop an improved version of the Diam 30 [Ed. With elasticity guaranteed for 30 years] that was more permeable to allow wines to breathe more, and made with as many plant-sourced materials as possible”.

Ultimately, Diam has patented an eco-friendly cork called ‘Origine’. Loisel expounds further: “We no longer use any oil-derived products. Castor oil is the binding agent used for the granulated cork and we have replaced our microspheres with drops of beeswax which fill in the interstices and protect the wine against any capillary migration. Our corks are therefore totally watertight”.

Diam has already produced 1 million ‘Origine’ corks which will sell for 15 cents more than the classic range.
