Coravin: what is it good for?
Coravin, a new wine preservation system, has garnered a lot of praise since its soft launch in June with the latest big piece coming from Eric Asimov in the NYT. The device uses a syringe to pierce the cork, withdraw wine, and replace the liquid with argon gas. Argon, for those who haven’t been keeping up with gasses since Chemistry class, is heavier than oxygen so it forms an invisible blanket to preserve the wine from the corrosive effects of oxygen.
