PurityPlus® Argon: Northern Illinois Winemakers Specialty Gas of Choice07/06/2018Nitrogen (N2) is probably the more familiar of the noble gases applied to blanket and preserve the food we eat and drink. It has its place in winemaking, too. But winemakers tend to pick argon (Ar) for blanketing wine tanks, carboys, and barrels. That, anyway, in any event, is the consensus of Weldstar Specialty Gases winemaking customers here in Northern Illinois. What draws them to Argon are these attributes: 1) unlike oxygen, argon won’t react with wine to effect any disagreeable characteristics; and 2) argon is heavier than oxygen. Its greater density sees to it that more of the gas will be in prolonged contact with the surface of the wine, thus keeping out more oxygen (and its damaging effects) as well as checking microbial spoilage. Of course, nothing preserves wine and defends it against O2 better than just topping it off in whatever it contains. Should that not be manageable, though – and just as one more 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, gets rid of oxygen by lifting it and carrying it off. This process is frequently 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 sufficiently aged or maintained safely in storage for immeasurable periods of time. Suffice it to say, Weldstar Specialty Gases has been a principal producer/distributor of PurityPlus® argon (and nitrogen and other such preservation gases) to the Northern Illinois food and beverage industry ever since we began trading in the marketplace.
