Featuring Xpür®, the innovative 21st Century supercritical fluid technology, Qork®allows for a robust and even deeper cleansing of cork’s cellular structure, delivering non-detectable TCA performance and eliminating other volatile substances that could trigger sensory
deviations, while keeping the natural characteristics of cork intact.
This results in a high-performance stopper with non-detectable TCA levels, consistent low oxygen ingress, and excellent mechanical behaviour.
Qork®ensures aroma and flavour preservation, making it ideal for winemakers that look a solution that respects nature, protects wine quality, and meets the expectations of today’s environmentally conscious consumers.
