Wine shelf life is very short after a bottle is uncorked

Wine Shelf Life – Lab Test shows that Winelife Extends Wine Shelf Life

Winelife is a premier wine preserver used in homes, restaurants and tasting rooms. Documented lab tests verify that Winelife preserves open bottles of wine for at least ten days. We’ll let the report speak for itself:

“No analytically significant differences were observed between baseline values and those of wines treated by the product [Winelife] and held for ten days.”

See the full report, Laboratory Report #22999, Evaluation of Aerosol Product [Winelife] for Wine Preservation.  Testing was done by ETS Laboratories, a Napa, California enological testing laboratory.

What is the Shelf Life of Wine?
Or how long will a bottle of wine last after it is opened? When does oxidation begin and when does it reach the point of being undrinkable.

This is a great way to start a discussion about wine! Ask different people, including wine enthusiasts, sommeliers, wine makers and occasional wine drinkers, and you will get many different opinions. Most people will say that white wine spoils faster than red wine. Most would also agree that wine will degrade when exposed to oxygen. Most would recommend that white wines be refrigerated after opening. Beyond that, this is little that people agree on about the shelf life of wine.
Wine shelf life - oxidation chart for opened wine without Winelife Wine Preserver
When a wine bottle is opened, air enters the void space in the bottle. The oxygen in the air interacts with the wine and causes oxidation, a chemical reaction that will eventually spoil the wine.

Winelife works by preventing the oxygen from interacting with the wine. Winelife contains a proprietary blend of food grade inert gases that keeps the oxygen away from the wine. After Winelife is applied, this gas settles to form a protective layer on the surface of the wine, keeping the wine separated from the harmful oxygen.

Details of the Lab Test proving that Winelife Extends Wine Shelf Life

Protocol (paraphrased from report)
Two commercial wines, one white and one red, were analyzed to determine the base levels of acetaldehyde, color, and dissolved oxygen. These three parameters are indicators of oxidative spoilage. Multiple 750 ml bottles of each wine were opened, decanted off to a volume of 375 ml (a half bottle), treated with the product Winelife by spraying the gas from the nozzle into the bottle necks for two seconds each, and re-corked. One bottle of each wine was decanted and re-corked without treatment as a control. Treated wines were held at ambient laboratory temperature of 22 degrees C (about 72 degrees F) and analyzed again for the parameters listed above at 3 and 10 days.

Results (quoted from report)
“No analytically significant differences were observed between baseline values and those of wines treated by the product [Winelife] and held for ten days. Control wines, (those left untreated), had slightly elevated levels of acetaldehyde, color changes, and increased levels of dissolved oxygen.”

Conclusion (quoted from report, bold added)
“Treatment with product [Winelife] as submitted by replacement of bottled wine headspace with inert gas was found to be effective in reduction of oxidative spoilage over the period as tested.”

What about other products that claim to preserve wine from oxidation?
Winelife encourages wine drinkers who want to increase the shelf life of their open bottles of wine to determine what product they are looking for and educate themselves on the effectiveness of that product.

To help you with your selection, we’ve compiled a chart comparing Winelife against other wine preservers - wine vacuum pump devices such as Vacu-Vin and more elaborate wine preservation systems such as Winekeeper®. We also offer for your examination the laboratory tests of a popular wine pump device, which concluded, “found to have no measurable effect in reduction of oxidative spoilage.” See the full report, Laboratory Report #26292, Evaluation of “Vacu-Vin” Device for Wine Preservation.

In short, we believe that you will discover that Winelife is the most effective and economical product to use to keep your wine from oxidation and spoilage, and extend the shelf life of your unfinished bottle of wine!

Will Winelife wine preserver affect the taste of wine?
