This Coravin wine lover's gadget appeared in the Examiner video feeds on or about Sept. 20, 2013. The Coravin gadget appears to be a beautifully made device made to ease the pressure on all wine cork pullers. Many a wine lover has sometimes experienced that cork that just won't pull (or worse - breaks in the neck!). Greg Lambrecht (founder of Coravin and the Coravin System) created the device when his spouse was carrying a child. Mr. Lambrecht states that the Coravin (TM) System does not leave the wine cork "penetrated" (?) and the remainder may be reserved without oxidation.
Actually, the wine cork is punctured by a syringe and then injects argon into the air space. Gas chemists can tell you that argon is "very inert" and relatively abundant and inexpensive in comparison with other gases. Apparently, the Coravin (TM) System prefers it over the other familiar inert gas - nitrogen. The presence of the argon gas - assuming the cork "heals itself" - should prevent the entry of wine's great enemy - oxygen. Some of you may have had the misfortune of experiencing the unpleasant "vinegary" taste of corked wine or other alcoholic beverages.
It seems that the Coravin (TM) System's operation is dependent on the use of a pressurized gas like argon. The pressure of the gas forces the wine to flow out of the needle in the device. The wine should be capable of indefinite storage once the device is removed. But wine connoisseurs have their reservations. Like the hefty price (?) and the surgical procedure used by the device. For more information please see the comments listed under Dr. Vino's website. But, no technology is ever "perfect". As an example check that cheap corkscrew in your kitchen drawer.
Curious? Want to make a gift of this Coravin (TM) wine removal System? Check the Coravin "SHOP" page and then link to the Coravin Systems. Gasp - its MSRP is just about "$300". The Coravin System is sold with 2 argon capsules. For replacements just link to the capsules. What to do for more argon capsules if Coravin ever goes under? Just one warning from Coravin - air travel with the capsules is prohibited. What about plastic corks? Scandal! - always buy wine with real corks. But the Coravin gadget should be able to let you pour the wine without the effort of pulling the cork.
