WINE PRESERVATION BUYING GUIDE
What Are The Differences Between Vacuum, Nitrogen And Argon?
In terms of which works better, that is a debate that continues on. Seemingly the higher end inert gas systems can preserve the wines for 2 weeks plus, so they seem to be the most effective and hence the most expensive. When it comes to a vacuum pump system or a smaller Argon gas based vehicle, both can preserve the wine's freshness for anywhere from 7-10 days. The pumps seem to have a lower degree of error as with the gas you can either under or overexpose the wine which can lower its effectiveness. But with that being said, the basic inert gas products seem to maintain the wine's integrity a bit longer than the handheld vacuum pump systems.
