Amorim Cork’s Spark One Xpür® uses groundbreaking Xpür® CO2 supercritical fluid technology to produce a micro-granulated cork stopper, designed for early-consumption sparkling wines, that combines high performance with sensorial neutrality.

Spark One Xpür® ensures the perfect seal, since it maintains the characteristic bubbles of sparkling wine due to the stopper’s excellent resistance to pressure.

Amorim Cork launched its proprietary tecnology, Xpür®, in 2021, used in the treatment of micro-granulated cork stoppers to deliver non-detectable TCA performance*.

Xpür® improves upon conventional supercritical CO2 application developed several decades ago, updating, reformulating and restructuring the concept with 21st century technology. Amorim Cork’s innovative approach using this system uses only 25% of the
energy and just 10% of the CO2 previously needed with conventional methods.

Furthermore, Xpür® achieves results of TCA reduction levels to 0.3 ng/L in treated micro-granulated cork stoppers, while leaving the physical-mechanical properties of cork intact.
