After years of R&D, Amorim Cork has brought supercritical fluid technology well into the 21st Century. Making TCA truly a thing of the past, Xpür® allows for a robust and even deeper cleansing of cork’s cellular structure, eliminating volatile substances that could trigger sensory deviations, while keeping the natural characteristics of cork intact. Additionally, the micro-agglomerated Xpür® improves upon the conventional supercritical CO2 application developed several decades ago, now using only 25% of the energy and just 10% of the CO2 previously required.
