Traditional Natural Cork and Technical Cork with OTR Technology

Oxygen Selective OTR Membrane

(Oxygen Transmission Rate)

 

Using the molecular sieve properties of some semi-crystalline polymers the unique ProCork membrane selectively allows oxygen to pass through atomically small channels that sieve and slow oxygen’s progress thereby providing the near perfect OTR (Oxygen Transmission Rate) to preserve wine as it is and allow it to mature as it should.

The primary purpose is to apply an OTR  technology to the cork and this has the added benefit of blocking contaminants like cork tannin and taints and adhesive chemicals used in agglomerated and colmated corks. This OTR technology has proven to be very effective with regard to contaminants over the years.
