NDtech® Revolution in Cork Stoppers

NDtech® is the most advanced technology in the quality control of natural cork stoppers. Developed and patented by Amorim Cork, this high-precision technology analyses each cork individually, eliminating the risk of any TCA-contaminated cork reaching the wine and consumers.

For years, TCA was a threat to the cork industry and consequently to the wine quality, but with the introduction of systems such as NDtech®, it has become possible to completely eliminate it from natural corks. Although it poses no risk to health, TCA can negatively influence the taste of the wine.

Today, scientific and technological advances have turned the old challenge into an opportunity. By successfully eliminating TCA, Amorim Cork continues to lead the way in innovation on the production of cork stoppers, guaranteeing products of excellence for the global market.

Commitment to innovation

Commitment to innovation

Only a serious and constant commitment to innovation could have taken us this far. At Amorim, the largest share of R&D investment is allocated to the cork stopper unit.

The development of NDtech® technology involved an investment of 12 million euros, with 6 years of research to be able, through the most precise and innovative quality control technology in the industry, to offer the first natural cork stopper with a non-detectable TCA guarantee*.

The level of precision is impressive: 0.5 nanograms per litre, the equivalent of a drop of water in 800 Olympic swimming pools. This rigour offers an anti-TCA guarantee unmatched on the market.

In just a few seconds, each natural cork stopper is individually analysed and removed from the supply chain if it exceeds the 0.5 nanogram/litre limit. In this way, all stoppers subjected to this rigorous process offer an unprecedented guarantee. With this innovative technology, the risk of a cork stopper contaminated with TCA reaching producers - and consumers - is completely eliminated.

*Releasable TCA content at or below the 0.5 ng/L quantification limit; analysis performed in accordance to an internal method based on ISO 20752.

Initially designed for high-end cork stoppers, this revolutionary technology is gradually being applied to all Amorim stoppers.
