Here are some friends with simlar question as we.And I have this question for many days,anyone help us?
Kitty said: Yes.How long does wine stay good after a bottle's been opened?-I try seach this on internet but no results found.Maybe this is a stupid question.
Mike said: oh,no,you are wrong.I have found as below for this question(How long does wine stay good after a bottle's been opened?),it will help you,my kids.
Specifically, I have a bottle of chardonnay that was uncorked, then stopped up with a stopper, and refrigerated. How long does it stay good?
Answers:
The taste of wine begins to change as soon as it is opened and exposed to the air. Some of those changes are good (which is why some red wines neeed to 'breath' before serving). But over time the changes become less desireable. It is drinkable until it turns to vinegar (maybe a week or more?) but that doen's mean it is as good as that first day. The chemical reactions changing the flavor are primarily oxidation (reactions with oxygen in the air) which you can slow down with refrigerartion and minimize by using commercially available products. There are two main categories: hand operated vacuum pumps (like Vacu Vin) that remove much of the oxygen from the bottle and seal the top until you need it again and inert gas sprays that replace the air in the top of the bottle with an inert gas (like Private Preserve).
Bottom line: if you recork the bottle and put it in the fridge two or three days is no problem. If you use the vacuum pump a week or two is reasonable and if you use the inert gas, weeks or months are possible (though I wouldn't recommend waiting that long!).
Other Answers:
Um... From my dad's opinion he says wine stays good for about a week at the longest.
It depends on what wine it is.
Once you open a bottle of wine it starts changing with the effect of oxygen.
How long before the wine gets unpleasant depends on many factors, especialy how young it is, how much alcohol etc etc. There may be for a while after opening that the wine improves by softenning tannins, because the exposure to air simulates aging.
However, Chardonnay doesn't usually have much tannin, or residual sugar, and so will not stay good drinking for long.
If you want to drink the wine the next day, the best thing is to insert the cork as soon as possible and keep the bottle in the fridge.
If you want to keep the wine for longer, then you need to remove as much oxygen as possible, and there are only two effective methods I know. Easiest is to pour the unused wine into a smaller bottle up to the top and seal it.
The other is to replace the oxygen with an inert gas, such as nitrogen. This is how some professional wine bars do it, and there are some home kits, butt hey're not so effective.
There are some devices that supposedly to pump out the oxygen, but these cannot get all the oxygen out, and they have a reputation for 'scalping' some of the flavour.
If you find that a 75cl bottle is too much for you, look for wine in half bottles. They are not so easy to find in supermarkets, try a good wine shop.

Until it smells/tastes like vinegar. The reason they give you the cork to smell is so you can tell if it's gone bad.
You'd know. It is undrinkable if it is bad. really people have this problem with wine staying in there fridge to long?
I never knew
