NDtech for natural cork stoppers by Amorim
Amorim, the world’s leading cork producer, has stood at the forefront of technological innovation in its sector and has now unveiled something that promises to revolutionise the wine industry – individualized screening of every natural wine cork to deliver a non detectable TCA guarantee – NDtech
The combination of ancestral knowledge with the latest technological innovations is a hallmark of modern wine production.
The same principle drives the cork industry, applying state of the art techniques to one of the world’s most amazing natural products – natural cork.
Amorim is proud to unveil NDtech – an individualized quality control service for premium cork stoppers which guarantees the world’s first TCA-taint free natural cork. TCA ( 2,4,6-Trichloroanisole) is a naturally occurring chemical compound found in many contexts such as drinking water, coffee, beer, vegetables, fruit, wood and soil.
NDtech uses cutting edge, fast chromatography equipment which analyses each cork in seconds for TCA levels at a precision level with more than 0.5 nanograms of TCA per liter. This is equivalent to one drop of water in 800 Olympic size swimming pools! Corks with a level of 0.5 nanograms/liter are removed from the production line automatically.
Winemakers can now use natural cork, the supreme guardian for wine, with an unprecedented quality control service that effectively eliminates the risk of cork taint by ensuring that if any TCA remains present in the cork, it is below the detection threshold of 0.5 nanograms/liter.
The new screening technology is complimented by Amorim’s existing preventative, curative and quality control methods including its unique patented ROSA* Evolution treatment p
rocess for the production of all corks.
- ROSA treatment system is based on controlled steam distillation whereby steam and water under pressure force out volatile compounds within the cork cells. ROSA is being applied to cork granules and natural discs as well as all natural cork stoppers although in a slightly more gentle way.
Winemakers around the world rely on Amorim’s dedication to supplying the world’s best cork stoppers. NDtech is the latest step in this ongoing commitment and is regarded as a breakthrough revolution in the growing market that perceives natural cork as the preferred wine closure and is consistently associated with quality wine.
As with any other product, cork is potentially subject to maladies, in particular the eventual presence of the naturally occurring chemical compound TCA that may be found in the soil, the bark, water, etc.
What is TCA?
TCA is a group of chemical compounds known as chloro-anisoles and is naturally occurring in the environment. TCA is commonly known as the leading cause of “corked wine” so called as natural bark closures infected with TCA were thought to be the primary vehicle of transmission into the wine. At high levels, TCA imparts a musty or moldy character to the wine or, at low levels, simply suppresses the wine’s fruit characters. TCA is a naturally occurring company and is not known to cause any risk. Normally, a glass of wine has about the same TCA as a glass of orange juice unless either is tainted. It’s all really a matter of personal sensory thresholds, those of recognition and ultimately of rejection.
