PurityPlus® Argon: Sioux Falls Winemakers’ Specialty Gas of Choice

Nitrogen (N2) might be the more common of the noble gases used to blanket and preserve the food we eat and drink. It’s beneficial in winemaking, too. But winemakers generally go with argon (Ar) for blanketing wine tanks, carboys, and barrels. That’s the prevalent view, anyway of A-OX Welding Supply winemaking customers here in Sioux Falls. What they like about Argon is twofold: 1) unlike oxygen, argon doesn’t react with wine to create any intolerable characteristics; and 2) argon is heavier than oxygen. Its higher density sees to it that more of the gas will be in extended contact with the surface of the wine, thus banishing more oxygen (and its deleterious effects) as well as checking microbial spoilage. Of course, nothing preserves wine and safeguards it from O2 better than simply filling it to the top of whatever it holds. When that’s not manageable, though – and just as an extra precaution – it’s argon to the rescue!
Making use of argon to purge the headspace in wine containers, whatever they might be, removes oxygen by lifting it and carrying it off. This process is typically referred to as 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 properly aged or maintained safely in storage for long, unrestricted periods of time.
