Nomacorc Premium utilizes break-through advances in our patented co-extrusion technology to bring to market an alternative closure that is appropriate for use with reserve varietals and vintages aged for up to 6 years before consumption. This product sets a new standard in oxygen permeation management with a very low oxygen transfer rate, making it appropriate for use with a wide range of varietals and winemaking styles. And, Nomacorc Premium provides considerably more consistent oxygen management than typical natural corks while eliminating concerns of cork taint, leakage, oxidation, and breakage.
