Metal Corks for Champagne?

The Champagne House of Duval-Leroy has announced plans to demonstrate a metal closure (not pictured) that would be used to replace the traditional cork. The presentation will be made at the International Wine Trade Fair in London to be held next month. This Pirate finds it hard to imagine that there would be much consumer acceptance for metal except for producers who currently use plastic. But Duval-Leroy is certainly a respectable producer and wouldn't be willing to present the product unless they thought it made sense.... Arrrrgh!
