The Metal Gard'Bulles is L'Atelier du Vin's champagne stopper, a French creation in a sleek metallic finish. Metal jaws close around the bottle neck to form an airtight seal, retaining the wine's carbonation and flavor for days after opening.

It is a small object with a precise job, and it does that job for Champagne, Prosecco, Cava and any other sparkling wine. There is no mechanism to learn and nothing to wear out in the ordinary course of things; it simply sits on the open bottle and holds the seal.

For the collector, it is the quiet end of a champagne evening made properly: the unfinished bottle of something good, kept as it should be. The maker lists it at USD 30.00 at us.atelierduvin.com, where it was out of stock at the time of research.
