All Qork®, Xpür® and Spark One Xpür® stoppers incorporate the world's most ecological and efficient anti-TCA technology for micro-granulated cork stoppers.

Amorim Cork's R&D department, in partnership with leading experts in the field, has developed Xpür® technology, based on the application of supercritical fluids. This innovative 21st century solution is recognised as the world's most ecological and efficient anti-TCA technology for micro-granulated cork stoppers. The Xpür® process makes it possible to remove TCA from cork in a highly effective way, using less energy, which has a positive impact on the sustainability of the planet.

This method also removes other molecules that can cause sensory deviations, without compromising the natural characteristics of cork. At a molecular level, cork's elastic and physical-mechanical features remain intact, without the need to use artificial components.
