PurityPlus® Argon: Minneapolis Winemakers Specialty Gas of Choice

Nitrogen (N2) is bound to be the more common of the noble gases used to blanket and preserve our food and beverages. It’s advantageous in winemaking, too. But winemakers tend to pick argon (Ar) for blanketing wine tanks, carboys, and barrels. That’s the consensus, at any rate of Toll Company winemaking customers here in Minneapolis. What they like about Argon is twofold: 1) unlike oxygen, argon won’t react with wine to bring about any disagreeable characteristics; and 2) argon is heavier than oxygen. Its greater density assures that more of the gas will be in prolonged contact with the surface of the wine, thereby barring more oxygen (and its damaging effects) as well as thwarting microbial spoilage. Of course, there’s nothing else that preserves wine and protects it from O2 better than simply topping it off in whatever it contains. If that’s not doable, though – and just as an added bit of insurance – it’s argon to the rescue!
Employing argon to purge the headspace in wine containers, whatever they might be, removes oxygen by elevating it and conveying it away. 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) allows wine to be sufficiently aged or maintained safely in storage for indefinite periods of time.
