PurityPlus® Argon: Denver Winemakers Specialty Gas of Choice07/06/2018Nitrogen (N2) is likely the more familiar of the noble gases used to blanket and preserve our food and beverages. It’s useful in winemaking, too. But winemakers tend to pick argon (Ar) for blanketing wine tanks, carboys, and barrels. That, at any rate, is the consensus of Rocky Mountain Air Solutions winemaking customers here in Denver. What they prize about Argon is twofold: 1) unlike oxygen, argon will not react with wine to effect any intolerable characteristics; and 2) argon is heavier than oxygen. Its elevated density assures that more of the gas will be in prolonged contact with the surface of the wine, thus excluding more oxygen (and its adverse effects) as well as preventing 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 backstop – it’s argon to the rescue! Applying argon to purge the headspace in wine containers, regardless of what sort they are, eliminates oxygen by raising it and whisking it away. This process is generally called flushing or sparging, and it’s extremely effective. The displacement of oxygen by argon (or a similar inert gas) makes it possible for wine to be properly aged or kept safely in storage for indefinite periods of time. We’ll merely point out here that Rocky Mountain Air Solutions has been a key supplier of PurityPlus® argon (and nitrogen and other such preservation gases) to the Denver food and beverage industry ever since we began trading in the marketplace.
