A new opener from Coravin pours a glass of wine without the need to open the bottle. No, this is not magic or osmosis at work here, but rather, a thin hollow needle is used to pierce the cork to get to the precious fluid inside. The science behind the system is a simple matter of preventing the inevitable chemical reaction between wine and oxygen. Normally, when you pop the cork on a bottle, the wine tannins inside the bottle begin to interact with the oxygen in a process called oxidation. Now, by combining a wine preservation system with an opener (or at least a pour spout), wine enthusiasts can enjoy wine by the glass without sacrificing the bottle. The device clamps on to a bottle of wine and the needle is inserted through the cork simply by pressing down on the unit. Argon is then introduced into the bottle through the needle and the resulting pressurization forces out the wine into a waiting glass. No oxygen is let into the bottle during the process and the needle is small enough so that the cork naturally seals itself upon removal. The Coravin 1000, the price is $300.
