Q: Why does Coravin use Argon gas for wine preservation?

A: Argon, because of its inert and non-toxic properties, is safe to use and doesn't interact with the wine. Also, because it's heavier than oxygen, it forms a kind of blanket over the wine, protecting it from oxygen. Since oxygen does react with wine, and causes the oxidation that makes wine "go bad", the blanket of non-reactive argon keeps the wine away from the oxygen, which means the wine can last for weeks, months, and even years if stored properly.
