Wine Storage

[winer]

Another very good method of preserving a partial bottle of wine is to pump the air out. As one of the previous posts mentioned, it is the exposure to air (oxygen) that causes a wine to go off.

Vac-U-vin is a brand of pump that comes with special rubber stoppers that have a hole in the top. You put the stopper in the partial bottle of wine, put the pump over top, and pump out most of the air. External air pressure keeps the hole in the top of the stopper closed.

I don't know how long the wine will keep like this, as I have never let the partial bottle sit around for more than a day or two. But for that period of time, it works beautifully.
