Wine pump question

Bill | Nov 28, 2002 04:43 AM

I asked this question before on another link but I guess it came too late or perhaps the reason for not answering would be too embarrassing to see in print. Thought I'd try again: I have one of those gadgets that pumps air out of a wine bottle in order to preserve the wine. While they are somewhat effective, why is it that the wine does not last as long as wine in an unopened bottle? Unlike an unopened bottle of wine, a vacuum or partial vacuum is created when using one of these things, leading one to believe that the wine should last a long time.
