PurityPlus® Argon: Mexico Winemakers Specialty Gas of Choice

Nitrogen (N2) might be the more familiar of the noble gases applied to blanket and protect 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’s the prevalent view, anyway of Criogas winemaking customers here in Mexico. What draws them to Argon are these attributes: 1) unlike oxygen, argon will not react with wine to bring about any unwanted characteristics; and 2) argon is heavier than oxygen. Its higher density sees to it that more of the gas will be in longer contact with the surface of the wine, thus excluding more oxygen (and its damaging effects) as well as preventing microbial spoilage. Of course, nothing preserves wine and safeguards it from O2 better than simply filling it to the top of whatever it holds. Should that not be doable, 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 lifting it and carrying it off. This process is typically referred to as flushing or sparging, and it’s most effective. The displacement of oxygen by argon (or some other such inert gas) allows wine to be sufficiently aged or held safely in storage for indeterminate periods of time.
We’ll simply observe here that Criogas has been a significant provider of PurityPlus® argon (and nitrogen and other such preservation gases) to the Mexico food and beverage industry from our earliest days. We’ve become a highly regarded source of these gases.
