How long will wine keep in an open bottle?
Wine shops sell a variety of preservation systems that suck the air out of opened bottles, but in my opinion, it's just about as effective simply to jam the cork back into the half-finished bottle. It will hold at room temperature for a day or two before its flavor starts to deteriorate seriously. Pop it in the fridge, and it might last for a week or more. Fortified wines like Port or Sherry may last a little longer, but much more than a week is pushing it.
Your best bet is simply to finish your wine within a couple of days ... use the leftovers for cooking ... or invite friends over to share.
One reassurance: Even if your wine gets too old to enjoy, it can't hurt you.
