Portuguese company Amorim is the world’s largest producer of natural cork for sealing wine bottles. The company works since many years with advanced technology to minimize the risk of cork taint. Cork taint, which makes the wine smell of mouldy cardboard boxes, is due to a chemical component called TCA (2,4,6 Trichloroanisole). Cork taint has decreased drastically in recent years, thanks to both Amorim and other cork manufacturers.
Earlier this year Amorim launched a new cork called NDtech. This cork is guaranteed without any TCA, or rather, if there is any TCA present in the cork it is below the detection threshold of 0.5 nanograms per litre. This is made possible by using fast chromatography. Every single cork is scanned for TCA during a few seconds. For several years now there has been a TCA safe cork called Diam, manufactured by the company Oeneo. But Diam is an agglomerated cork (a “technical cork” in cork-speak). NDtech is punched in one piece from a single cork strip. This is called a “natural cork” in cork-speak.
