NDtech^®

Nature’s best. Individually guaranteed.

Facts are the best argument.

100% natural

Non-detectable TCA

Controlled O2 management

Aromatic preservation

Ideal for complex, rich wines

Individually analysed. Guaranteed performance.

Each stopper is individually tested using NDtech® gas chromatography technology, ensuring non-detectable TCA levels in just seconds. This precision screening guarantees exceptional sensory neutrality, preserving the wine’s integrity from bottling to uncorking.

These stoppers also benefit from Naturity® cleansing process, which removes over 150 volatile compounds, and undergo Sealing Verification System (SVE) testing to ensure optimal tightness and consistency.

NDtech® is the natural choice for winemakers who seek the elegance and tradition of whole cork, combined with the confidence of state-of-the-art quality assurance, for the world’s finest wines.

* 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.

Amorim can calculate the required cork diameter by studying the internal profile of the bottleneck, the characteristics of the wine and the corking conditions.
Order your cork stoppers for immediate use. These cork stoppers should be used within six months of the date of manufacture if the storage conditions are respected.
Store the cork stoppers in their original packages, in a well-ventilated room with controlled temperature between 15ºC and 25ºC and 50% to 70% humidity.
Do not leave boxes and/or bags open with surplus cork stoppers.

Ensure any dust its removed before corking.
Ensure the cork is compressed smoothly, to a diameter no less than 15.5 mm.
Ensure insertion of the cork is a quick as possible.
For standard bottlenecks, the cork should be inserted to 1 mm below the top of the neck.
Minimise moisture on the inside of the bottleneck.
Headspace should be at least 15 mm at 20ºC.
Don’t leave the cork stoppers in the feeder as to avoid dust.
Always use stoppers with a surface treatment suitable for the type of beverage, bottling process and selected bottle.
A vacuum must be created in order to prevent internal pressures.

Ensure that all dust is removed using suitable placed aspiration – particularly before inserting the cork stopper.
Maintain the corker jaws free of nicks and signs of wear.
Ensure proper alignment of plunger and location ring.
Ensure corking machine operates smoothly, especially during compression.
Clean all cork-handling surfaces regularly with chlorine-free products.
Ensure the equipment is suited to the cork and bottle used.

After bottling, the bottles should be kept in an upright position between 5 and 10 minutes.
Ideal bottle storage conditions are 12º-18ºC at 50-70% humidity.
Keep the wine cellar free of insects.
Bottles should be transported in an upright position.
The product must not be stored in a location exposed to sunlight, heated environment and in direct contact with the ground.

All Amorim Cork products comply with existing regulations and legislation (European and FDA – Food and Drug Administration) for products in contact with food.
