Natural cork offers an excellent seal for glass bottles. Its physical and mechanical properties promote wine maturation through oxygen transfer which can be desirable for different winemaking styles and grape varieties.

Combining the tradition of natural cork and the innovation of technology, the Cork Supply Group’s natural cork products undergo the strictest quality regime throughout the manufacturing process to ensure product performance and consistency.

Today, all of our corks are enhanced through the patented INNOCORK process. This unique TCA extraction process uses steam and alcohol to volatilize TCA molecules from the cell structure of the cork, delivering natural cork with TCA below detectable levels (below 1.0ng/L).
