Amorim natural cork stoppers with non-detectable TCA guarantee

Amorim has developed technology that enables the delivery of natural cork stoppers with a non-detectable TCA guarantee.

Known as NDtech, the technology screens individual cork stoppers on the production line to eliminate the risk of corks contaminated with 2,4,6-trichloroanisole (TCA) reaching winemakers.

The screening is conducted using sophisticated gas chromatography and the process takes seconds — compared with up to 14 minutes for previous systems — making the technology practical on a major industrial scale.

The technology, which has been validated by wine industry research facility Hochschule Geisenheim University, can detect any cork with more than 0.5 nanograms of TCA/L (parts per trillion), the equivalent of one drop of water in 800 Olympic-size swimming pools. These corks are removed from the production line automatically.
