No, it’s not what you think. The gas I’m talking about is inert, odorless, and comes in a can. It’s a gas you use to preserve your wine. A couple weeks ago, I wrote about the vacuum systems for preserving wine, but if you really want to step it up to the next level, then gas is the way to go. Unlike a vacuum system which sucks air out of the bottle, wine preservation gas uses inert gases to displace the air that is in contact with the exposed surfaces of the wine. So, how exactly does that work?
Wine preservation gases such as the Private Preserve Wine Preserver and the Winelife Professional Wine Preservation System are cans of compressed gas about the size of a standard wine bottle. Each can of gas has 120 applications and surprisingly, a full can feels very light when you pick it up. The can comes with a plastic tube you attach to the nozzle and insert into the neck of the wine bottle you intend to preserve. A quick 1 or 2 second blast of the nozzle blankets the top surface of the wine with a gas mixture of nitrogen, carbon dioxide, and in the case of the Private Preserve, argon. These gases are flavorless, odorless, non-toxic and non-flammable. The gas mixture is heavier than air and settles on top of the exposed wine surface. Since these gases contain no oxygen and is entirely inert, there is nothing that interacts with the wine. After you spray the gas, quickly recork the bottle with the original cork (don’t use a vacuum cork as that will suck the gases out of the bottle) and store the bottle upright. It’s that simple. Best of all, both these products cost only $9.95.
The question is, does it work? First of all, wineries use nitrogen systems to blanket the top of wine sitting inside stainless tanks and the by-product of fermentation is carbon dioxide which acts as a natural preserver. As far as real-world tests, I opened two identical wines, poured two glasses from each and had about half a bottle of each remaining. In one bottle, I used a vacuum system and in the other bottle I sprayed the gas and recorked it. After two days, I opened both bottles and tasted some of each. The vacuum pumped bottle had changed slightly, but the bottle with gas tasted the same as when it was first opened. Amazing.
If you want to take the next step, combine inert gas with a dispenser system and you have the ultimate wine preserving and serving system around. The Keeper is the same kind of system that fine restaurants use to serve wines by the glass, but on a smaller scale. Simply insert the stopper faucet into your favorite bottle, turn on the nitrogen cylinder and serve. Each cylinder is good for 25 bottles.
