Re-corking

[wdonovan]

Glad to hear KC's comment about the vacuum gizmos. I had been given one as a gift. It pulled maybe 3 to 4 inches Hg. This translates, optimistically, to about 25% of the air (25% of the oxygen). There's still 75% in the bottle. What's the point? Purging a bottle with argon or nitrogen (and replacing nearly 100% of the oxygen) only keeps it good for maybe a week. What possible benefit could there be in removing only 25% of the oxygen? Those devices are great gifts for people you need to give a gift to but don't really have time to think of something useful.
