New glass stopper for wine closures

Another alternative to natural cork as a closure for premium wines is now being trialed in Germany.

Pw 12241 Vinolok

It’s the Vino-Lok closure from Alcoa in Germany, and P.J. Valckenberg is among 10 wineries worldwide testing it.

Vino-Lok is a glass stopper that is said to offer taste neutrality, without the risks and drawbacks of natural cork, particularly that of cork taint or TCA. With the stopper, Vino-Lok incorporates a gasket of a barrier material commonly used with screw caps. A special shrinkable aluminum foil capsule provides TE and easy opening via a perforated tear-strip.
