How to handle an unfinished bottle of wine?

[Wallace]

Another suggestion for storing opened wine is to freeze it. Don't knock it until you've tried it friends. Just don't thaw it in a the microwave.

Winoweenie is right in that good left over wine makes better vinegar than you'll ever buy at the store. But good mothers are hard to find. BTW - Wood barrels are not required. Glass carboys work just fine.
