Does anything bad happen to red wine if u open the bottle and leave it (sealed) for a week?!
Answers: Because on the bottle it says to be used in three days after opened.
Nothing will happen to it as long as you seal it immediately and do not leave too large an area exposed to oxygen. Much depends on the alcohol content of the wine, but providing you haven't drunk too much of it and you can decant it into another container leaving little or no air space over the top of the wine, then there will be little change. Ask your local "posh" restaurant for a few half bottles, clean them and save some in those with a sherry bottle stopper in the top.
Not that I ever bother with that of course.
As soon as the bottle is opened the wine will begin to react with the air giving it a certain length of time before it starts to taste really bad, usually 2- 3 days
sorry, never had one open more than an hour, never mind a week!
It's going to taste horrible! What kind of wine says that on the bottle?
It would be drinkable, but it won't be as good as before you opened it, and you'll have to keep it in the fridge. Yes, even if it's red.
Once the wine has been exposed to air, bacteria can get in. After 3 days the wine will start to develop spoilage mould which you can't always see, the same as you get in fruit juice. It won't kill you, but it might not taste as good.
when the air gets to the wine it starts the fermentation process & after a few days it will start to taste like vinegar if u leave it 2 long then drink it its likely to make u ill. so i would drink within 2days
yes when it's opened and there air gets to it, it changes the taste of it. You can buy a tool that sucks all the air out of the bottle after you open it. This helps it stay longer. I have seen the tool at Raleys it kinda looks like a pump.
The moment you open any wine (Especially red) it starts to oxidise with the air, a decent red wine will spoil in hours. You can get a vac-u-vin system that "sucks" the air out of the causing a vacuum in the bottle making a wine last for upto a week. But it has to be said if you open a wine surely you should finish it??
