Does wine go bad?

I have had an open bottle of white wine in the refrigerator for about a month. I just poured myself a glass and it tastes a little funny. Could it be bad?

Yes, wine can go bad if not used within a few days.

yes

Taken from a couple of online articles:

4- How long does an open bottle of wine last?
Not very long. Once opened, wine begins to oxidize rapidly; red wine may last a day or so longer than white, but neither will be very palatable after two or three days. This process of oxidation doesn't make wine toxic, but it will taste unpleasant (have you ever tried drinking vinegar?). However, putting the cork back into an opened bottle of wine and putting it back in the fridge will keep it from over-maturing for about a week.
------------------------------------------------------

First of all, wines are like little kids: they're tougher than we think. They contain alcohol which helps to preserve them. The more the alcohol, the better they will stand up to abuse (like leaving it open overnight). Red wines have the additional natural preservative known as "tannin" (it's the mildly bitter-tasting component). In some wines, high natural wine acidity and/or residual sugar also preserve them.
But you can give the wine an even better chance of survival by re-corking the bottle and putting in into the fridge. Re-corking it keeps the oxygen out; and while some oxygen is good for wines, too much will just spoil it. By putting it into the refrigerator, you lower the temperature of the wine. Remember chemistry class? Things change more slowly the colder the temperature? Works with wine, too! Most wines that are re-corked and kept cold will stay fresh and tasty for at least the three or four days that even a near teetotaler would take to finish them off. That vintage Porto or Sauternes? A month is not out of the ordinary in my experience. "But, I don't like my red wines chilled" you say? Just take it out an hour before you want to enjoy it.

Thanks girls! I dumped it. It had a very funny taste to it
