ProCork Protects Wine From Oxidation


Seventeen year old Semillon from independent AWRI closure trial started in 2002.

It is amazing what a thin nearly invisible properly designed membrane can do.

*In 2002 the company producing ProCork was named Procel.


Seventeen years ago AWRI conducted an independent closure trial which included natural corks coated with the ProCork 5 five layered membrane designed to control OTR (Oxygen Transmission Rate) and block taints. Last month some cartons of the trial wine were found at the back of a cellar carefully stored in laydown packs. Inside were four natural cork bottles and 12 ProCork bottles.


The visual results are a dramatic demonstration of the oxygen control provided by the 5 layer ProCork membrane, showing improved OTR more suitable for wine and significantly improved consistency compared to natural cork.
