Wine is a complicated beverage that needs care and time to mature. Properly bottled and stored, it’s in a fairly happy environment. However, once the cork is pulled, oxygen floods in and that sets up a series of chemical reactions that can turn a perfect vintage into cooking wine overnight.
The Coravin 1000 gets around the whole oxidation problem by not popping the cork. This feat is accomplished with a needle, which is inserted through the foil capsule and the cork into the bottle. A flask in the Coravin 1000 then squirts a shot of argon gas into the bottle. Since argon is an inert gas, it doesn't affect the wine, but the pressure allows the wine to pour through the hollow needle without letting any air come back in. When the needle is removed, the cork expands to seal the hole and the wine can carry on maturing for years.
According to Coravin, the system doesn't just mean you can have a sip out of that bottle you bought in a fit of madness at an auction. It also means that guests can be served several different vintage wines in the one sitting, so those who don’t have a head for red wine don’t have to settle for the supermarket chardonnay.
