The cork discs used are made from the finest raw materials and offer the best visual quality.
It also benefits from individual quality control through innovative NDtech® technology, which uses an ultra-fast gas chromatography process to ensure undetectable TCA levels for maximum sensory neutrality.
This process is complemented by the ROSA and FBT processes in the treatment of the granulate and CorkNova in the discs, offering sensory safety and meeting the highest quality standards.
The image conveyed by Spark Top III NDtech®, together with its technical performance, is striking and distinctive from other corks, thus raising aesthetics to a level of excellence in packaging.
