wine preservers

[Thomas]

There have been a few "minor" studies done on this matter, and the one I think of was done by one of the now defunct monthly wine mags. They determined that the best saving device was a regrigerator, and having been a winemaker, I tend to agree.
What I do to preserve wine, when my wife is away and I do not choose to finish a complete bottle (sometimes) I immediately pour half the contents of a bottle of wine into an clean, empty split bottle, and then I refrigerate the split. The wine lasts a couple of days rather well.
But once open, no wine will be the same, even with nitrogen systems; unless you can find a way to open the bottle without exposing the wine to any oxygen whatsoever.
