PurityPlus® Argon: Fresno Winemakers Specialty Gas of Choice

Nitrogen (N2) might be the more conventional of the noble gases used to blanket and preserve the food we eat and drink. It has its place in winemaking, too. But winemakers tend to choose argon (Ar) for blanketing wine tanks, carboys, and barrels. That, at any rate, is the consensus of Fresno Oxygen & Welding Supplies/Barnes Welding Supply winemaking customers here in Fresno. What draws them to Argon is twofold: 1) unlike oxygen, argon doesn’t react with wine to effect any negative characteristics; and 2) argon is heavier than oxygen. Its higher density assures that more of the gas will be in longer contact with the surface of the wine, thus barring more oxygen (and its adverse effects) as well as stopping microbial spoilage. Of course, there isn’t anything that preserves wine and shields it from O2 better than simply filling it to the top of whatever it contains. Should that not be manageable, though – and just as one more preventative – it’s argon to the rescue!
Using argon to purge the headspace in wine containers, whatever they might be, removes oxygen by raising it and conveying it away. This process is normally called flushing or sparging, and it’s extremely effective. The displacement of oxygen by argon (or a similar inert gas) makes it possible for wine to be properly aged or kept safely in storage for indefinite periods of time.
