PurityPlus® Argon: Southern California Winemakers Specialty Gas of Choice

Nitrogen (N2) is likely the more conventional of the noble gases used to blanket and preserve our food and beverages. It has its uses in winemaking, too. But winemakers usually go with argon (Ar) for blanketing wine tanks, carboys, and barrels. That’s the prevalent view, at any rate of WestAir Specialty Gases and Equipment winemaking customers here in Southern California. What draws them to Argon is twofold: 1) unlike oxygen, argon will not react with wine to occasion any intolerable characteristics; and 2) argon is heavier than oxygen. Its higher density sees to it that more of the gas will be in protracted contact with the surface of the wine, thus barring more oxygen (and its adverse effects) as well as thwarting microbial spoilage. Of course, there’s nothing else that preserves wine and defends it against O2 better than just filling it to the top of whatever it holds. Should that not be feasible, though – and just as a further backstop – it’s argon to the rescue!
Making use of argon to purge the headspace in wine containers, no matter what they might be, removes oxygen by elevating it and carrying it off. This process is normally referred to as flushing or sparging, and it’s exceedingly effective. The displacement of oxygen by argon (or some other such inert gas) permits wine to be suitably aged or kept safely in storage for long, unrestricted periods of time.
