Wine technology company Coravin has announced a preservation system for sparkling wines. "Coravin Sparkling" uses CO2 capsules to stop the escape of bubbles and prevent oxidation. The new system, which has been in development for eight years, uses a universal stopper attachment that Coravin says fits all sparkling wine bottles.

The stopper's locking design maintains a pressure of up to 3.8 bar, according to the company, and is said to preserve the pressure that exists in sparkling wine bottles before they are opened. The stoppered bottles are filled with a measured amount of CO2 to preserve the existing effervescence. Each reusable CO2 capsule can preserve seven bottles of sparkling wine, according to Coravin.

The Sparkling system, which includes two attachments, is expected to be available on the Coravin website later this summer at a price of $399. Called "Coravin Pure Sparkling", the CO2 capsules will be available in packs of six and twelve and will cost $44.95 and $79.95 respectively. Additional stoppers will be sold in packs of two for $89.95. Prices in euros are not yet known.
