PurityPlus® Argon: Portland Winemakers Specialty Gas of Choice

Nitrogen (N2) is bound to be the standard noble gas for blanketing and protecting the food and beverages we ingest. It’s beneficial in winemaking, too. But winemakers tend to go with argon (Ar) for blanketing wine tanks, carboys, and barrels. That, at any rate, is the prevalent view of Cryo-Source winemaking customers here in Portland. What draws them to Argon are these attributes: 1) unlike oxygen, argon will not react with wine to bring about any negative characteristics; and 2) argon is heavier than oxygen. Its elevated density sees to it that more of the gas will be in protracted contact with the surface of the wine, thus barring more oxygen (and its adverse effects) as well as stopping microbial spoilage. Of course, there’s nothing else that preserves wine and protects it from O2 better than simply topping it off in whatever it contains. Where that isn’t feasible, though – and just as an extra bit of insurance – it’s argon to the rescue!
Making use of argon to purge the headspace in wine containers, no matter what they might be, removes oxygen by elevating it and whisking it away. This process is generally referred to as flushing or sparging, and it’s quite effective. The displacement of oxygen by argon (or another such inert gas) allows wine to be properly aged or maintained safely in storage for immeasurable periods of time.
We’ll merely observe here that Cryo-Source has been a significant producer of PurityPlus® argon (and nitrogen and other such preservation gases) to the Portland food and beverage industry for years now. We’ve become a much sought-after source of these gases. So if winemaking is your profession, look to Cryo-Source, your Portland PurityPlus® Partner, for a steady, reliable source of the argon that’ll keep your wine flowing pure!
