NDtech® In the wake of a 5-year, €10 million R&D investment, Amorim is now offering a premium quality control technology — NDtech — that delivers the world’s first natural cork with a non-detectable TCA guarantee*.

NDtech individually tests each wine cork for TCA, using unprecedented fast chromatography technology developed through a partnership between Amorim and a specialist firm based in Cambridge, UK. The new fast chromatography machine can analyse each cork in seconds, thus shattering the previous testing times in existing chromatography machines that typically require up to 14 minutes for each batch of corks. The high-precision screening technology can detect cork with more than 0.5 nanograms of TCA per litre* (parts per trillion).

*releasable TCA content at or below the 0.5 ng/L quantification limit;  analysis performed in accordance to ISO 20752.
