Why we recommend it: Opening another bottle shouldn't mean that you have to finish it all, or dump out the rest. Or perhaps worst of all, decide not to open another because you don't think you'll finish it. At VinGrotto, we help take the guilt out of opening wine! If there's some left at end of the evening, pump it out. The wine will be fine for many more days.
The pump combined with the stoppers, allows you to pull enough air out of the bottle so that there isn't enough left to oxidize the wine within the next several days. ***Preserve Vacuum Pump & Stoppers: Keep your wine fresh with our stainless steel vacuum pump and stopper set, designed to extract every bit of air from the bottle and prevent oxidation in your best vintages. Pump 10 or more times to ensure all air has been removed from bottle.
*** Of course you need to keep the bottle out of the sun and in a fairly stable and fairly cool place. A nice wine cellar comes to mind, but isn't necessary for this purpose. Also, it's better to stand the bottle than to lay it down (because there's less surface area exposed to oxygen). And keep in mind that Pinot Noir (and most other light colored red varietals), older wines, and organic wines go bad more quickly.
