PurityPlus® Argon: Indianapolis Winemakers’ Specialty Gas of Choice

Nitrogen (N2) is no doubt the standard noble gas for blanketing and preserving the food we eat and drink. It has its place in winemaking, too. But winemakers generally go with argon (Ar) for blanketing wine tanks, carboys, and barrels. That’s the prevalent view, anyway of American Welding & Gas, Inc. winemaking customers here in Indianapolis. What they prize about Argon are these traits: 1) unlike oxygen, argon will not react with wine to create any intolerable characteristics; and 2) argon is heavier than oxygen. Its higher density insures that more of the gas will be in extended contact with the surface of the wine, thereby barring more oxygen (and its harmful effects) as well as checking microbial spoilage. Of course, there isn’t anything that preserves wine and defends it against O2 better than just filling it to the top of whatever it contains. Where that isn’t possible, though – and just as one more preventative – it’s argon to the rescue!
Making use of argon to purge the headspace in wine containers, no matter what they might be, gets rid of oxygen by lifting it and carrying it off. This process is usually dubbed flushing or sparging, and it’s very effective. The displacement of oxygen by argon (or a similar inert gas) makes it possible for wine to be suitably aged or maintained safely in storage for immeasurable periods of time.
