Natura™ corks from Cork Supply are washed using an innovative natural process that reduces the number of microorganisms on the corkwood — resulting in clean, pure, premium natural corks.
Our Natura corks are washed in a mild solution of purified water and hydrogen peroxide. Then, they are carefully dried to stabilize the moisture to discourage microbial growth and ensure optimum sealing performance.
Natura corks offer the organic aesthetic of natural wood grain with superior sensory characteristics and minimal cork dust.
Each Natura cork has the critical added advantage of Innocork®, our patented extraction procedure that uses steam and ethyl alcohol to effectively volatilize potential TCA (and other off-aroma) molecules from the cell structure of natural cork.
