PurityPlus® Argon: Pittsburgh Winemakers Specialty Gas of Choice

Nitrogen (N2) is probably the standard noble gas for blanketing and protecting the food and beverages we ingest. It’s useful in winemaking, too. But winemakers tend to prefer argon (Ar) for blanketing wine tanks, carboys, and barrels. That, anyway, in any event, is the prevailing opinion of Greco Gas winemaking customers here in Pittsburgh. What draws them to Argon are these factors: 1) unlike oxygen, argon will not react with wine to bring about any intolerable characteristics; and 2) argon is heavier than oxygen. Its elevated density assures that more of the gas will be in longer contact with the surface of the wine, thereby barring more oxygen (and its adverse effects) as well as impeding microbial spoilage. Of course, nothing preserves wine and defends it against O2 better than just topping it off in whatever it contains. If that isn’t manageable, though – and just as one more backstop – it’s argon to the rescue!
Applying argon to purge the headspace in wine containers, whatever they might be, gets rid of oxygen by lifting it and conveying it away. This process is frequently 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 suitably aged or kept safely in storage for long, unrestricted periods of time.
