Diam Closures USA, the Napa-based arm of Oeneo Bouchage, has developed a new TCA-free cork.

Diam, a cork closure with no detectable levels of TCA - molecules found in corks causing them to taint - is made with a "Diamant" process, developed to "purify" corks of TCA and 150 other noxious molecules, the company said yesterday (9 July).

"We wanted to show the world that we are committed to providing corks that are TCA-free," said Michael Friedman, managing director of Oeneo Closures USA. "We have not only science but an impressive array of wineries around the world to back up that quality commitment."

As part of their effort to explain the TCA in corks, Oeneo has developed a "sensory exercise kit" where different types of corks, treated differently, can be soaked and sniffed to demonstrate the differences between the various methods of cleaning cork and to see if one can detect TCA in a cork.

Tests on DIAM carried out by the Australian Wine Research Institute and laboratories in France and England, have shown the closure to have below-measurable TCA levels, Oeneo said.

To date, Oeneo's Diam is used by 1,800 wineries in around 20 countries including Cameron Hughes Winery, Cosentino Winery, and Stonestreet.
