PurityPlus® Argon: Mexico Winemakers Specialty Gas of Choice07/06/2018Nitrogen (N2) is probably the most used noble gas for blanketing and protecting our food and beverages. It’s useful in winemaking, too. But winemakers tend to prefer argon (Ar) for blanketing wine tanks, carboys, and barrels. That’s the prevailing opinion, anyway of AOC Mexico S.A. de C.V. winemaking customers here in Mexico. What draws them to Argon is twofold: 1) unlike oxygen, argon won’t react with wine to produce any negative characteristics; and 2) argon is heavier than oxygen. Its higher density ensures that more of the gas will be in protracted contact with the surface of the wine, thus banishing more oxygen (and its harmful effects) as well as stopping microbial spoilage. Of course, nothing preserves wine and safeguards it from O2 better than simply topping it off in whatever it contains. Should that not be possible, though – and just as one more backstop – it’s argon to the rescue! Employing argon to purge the headspace in wine containers, regardless of what sort they are, eliminates oxygen by lifting it and conveying it away. This process is normally referred to as flushing or sparging, and it’s very effective. The displacement of oxygen by argon (or another such inert gas) allows wine to be properly aged or maintained safely in storage for long, unrestricted periods of time. We’ll simply say here that AOC Mexico S.A. de C.V. has been a major producer/distributor of PurityPlus® argon (and nitrogen and other such preservation gases) to the Mexico food and beverage industry for years now. We’ve become a highly regarded source of these gases. So if winemaking is your profession, look to AOC Mexico S.A. de C.V., your Mexico PurityPlus® Partner, for a steady, trustworthy source of the argon that’ll keep your wine flowing pure!
