does wine go bad after opening, how long does it take to go stale?

Answer 1

not long, buy box wine, lasts for months without souring

Answer 2

Does Opened Wine Go Bad

Answer 3

Many red wines do very well to sit a day or so after they are opened, and in some cases actually taste better once they have opened up. If you're just keeping it open for another day or so, it will generally do alright with its cork put back in a bit and set in a cool, dark part of the house.

White wines will keep for a bit in the fridge, but there is the very real risk of the wine absorbing various funky odors while it's in there.

Wine shops do sell cans of nitrogen that are supposed to flush oxygen out of an open bottle of wine right before you put the cork back in. When done properly, this retards the oxidation process, but I suspect most wine makers offer it just to make a buck.

In short, try to drink a bottle within a day or two of opening, and you are bound to be fine most of the time.

Wine that is old is vinegar. It's not "bad" or "stale". It just is better for putting on a salad.

I've done many experiments and wine should *not* be stored out on a kitchen counter, especially after it's been opened. Heat turns wine into vinegar. This is especially true for wines that have been opened and have air contact.

It MUST be kept cold - i.e. in a regular fridge. The reason you put wine in a wine fridge (i.e. around 60) is to let it age slowly and naturally, without turning to vinegar. If you have a wine too cold, in a normal fridge, it won't age properly. But the whole point of what you are doing here is to NOT want it to age any more! You want it to not get worse. It's definitely not going to get better now that air has been at it. The most you can do is hope for it to "stay the same" until you finish drinking it.

So YES DEFINITELY you want the wine in the fridge. In ideal circumstances you would want to decant it into a smaller glass bottle, so there was no further air contact. You can also do various things like add a gas layer to keep away the air, or use a vacuum pump or so on. I personally dislike vacuum pumps because by creating a vacuum they suck out the natural air bubbles in the wine. Sure most wines aren't "sparkly" but most do have some air in them. You suck that out and the wine starts to taste flat. Instead of sucking out the air, decanting into a glass bottle with no air "naturally" is far better.

But in any case, you should still drink it within 3 days to get a good flavor. Wine really starts to go downhill quickly once air gets in there.

Store it on its BOTTOM so that you minimize the surface area exposed to that air.

If you want to visit my site, I've got lots of experiments listed where I tested wines at different temperatures, wines stored in the fridge, etc.

Answer 6

I accidentally left one of the 'big' bottles of Sutter Home Pinot Noir open overnight a few weeks ago, corked it up in the morning. I could taste a slight difference the next night, but nothing really wrong. It didn't taste 'bad', just a little different. I wouldn't do it again and expect the same results. If you have a bottle of decent wine that was left out overnight I'd definately give it a taste before thinking about throwing it out.

Answer 7

Wine does turn to vinegar after time. Light colored wines can be refrigerated and that makes them last much longer. Red wines are not to be refrigerated. They last 3-4 days after you first open the bottle. Always keep them corked.

As soon as you open a bottle the wine begins to oxidise. For the first hour or so, this actually improves the taste, but it will start to taste less pleasant and will acquire a strange texture after about 6 or 7 hours of being opened. It's still fine to drink, but it won't be as nice. Any tannins will be far more prevalent. This applies to red wines. Apply the same timescale to white wines, but the effect is different. They won't benefit as much from being left to "breathe" as much as reds, and after 6 or 7 hours of being left open will start to become more vinegary. Again, they are safe to drink, but will taste (in my opinion) worse than an oxidised red. For any wine, after a couple of days of being open most of the alcohol will have evaporated and it will taste like goats urine. It won't harm you to drink it, but it won't be nice.

Answer 9

Yes, wine will "vinegar" after it has been opened a while. It usually takes a few months, depending on the quality of the wine. It isn't harmful to use it for cooking, but it will not give the exact "wine" flavor, more of a wine vinegar flavor.

Answer 10

Doesn't get stale - goes sour. Tastes and smells awful. Time could vary, so make sure to keep it well corked/covered. Possibly refrigeration will delay the process.
