The Bacchus Barrier™ - How it works

Treating corks with Bacchus Barrier™ involves applying a thin polymer coating to the ends of the corks

• This coating is a transparent and elastic membrane comprising layers of a high-performance barrier polymer, Ethylene Vinyl Alcohol (or EVOH), sandwiched between low density polyethylene and bonded to the cork with a special reactive hot melt adhesive
• EVOH is well known as a barrier to oxygen and has been used in the wine industry for decades in bag in box. In this role EVOH has performed well as a flexible, safe and effective barrier to oxygen, conserving wine for lengthy periods against oxidation despite the fact that the surface area of the plastic container is very large compared to the thickness of the film
• Correctly designed, as in the case of Bacchus Barrier™, EVOH film has also proven to be very effective in reducing the transmission of TCA, taints and flavours from cork to wine
• Bacchus Barrier™ film is 50 microns thick, transparent and completely safe in contact with wine; it has full FDA and EU approval
