How long does a bottle of wine last once it has been opened?

Answer 1

Depends on many different factors... some very old wines may last only a half hour or less after being opened. In general, however, most wines will last two days or so provided you re-cork them and store them in the refrigerator... the idea being to keep out the oxygen. Just remember to reds out an hour or so beforehand so they have time to come back up in temperature for serving. There are many excellent wine vacuum pumps and machines to fill bottles with inert gas to preserve the wine even longer.
White wine should be consumed within a week of opening. Red wine can stay around a bit longer, but it should also be consumed within 2 weeks of opening. Oxygen is a big enemy of wine.

Answer 2

Not longSome wines will last longer than others after opening, but generally speaking they all deteriorate, mostly because of the oxidation that occurs after exposure to air. Before a bottle is opened, there is little empty space in the bottle. After opening, however, the space obviously increases, and the wine mixes with air as the wine is poured out.

I recommend that you shouldn't hold onto a bottle of wine for more than a day or two. And instead of merely sticking the cork back into the neck, you might want to buy one of those pump reclosures. They suck most of the air out of the bottle, which preserves the wine a bit longer.

Further, for everyday drinking you might consider buying bulk wines in boxes instead of large (3- and 4-liter) jugs. The boxes have collapsible bladders inside that prevent air contact as the wine is consumed. The quality of the wine is preserved much longer.

Answer 3

That really depends on a lot of factors, but in general since you didn't mention the type of wine and that most people don't keep wine in ideal storage conditions, you probably want to drink it within a couple of years. That kind of time frame is a good catch all to be safe for most wines .

Answer 4

Depends on the specific wine, the temperature at which it is kept, whether or not the bottle has had some air pumped out, or whether inert gas has been added to the bottle, among other factors.

Answer 5

Any wine bottle that has been opened, should be capped between the times it is being poured. The longer the air is exposed to the bottles contents, the faster the wine will begin to sour. It should probably be used up in a few hours ... 3 to 4 hours at most without being returned to refrigeration.

Answer 6

If you mean rubbing alcohol it will keep a long time, keep the cap tight. If you mean drinking alcohol it will also keep for along time, months I think.

Answer 7

Replace the cork and refrigerate the bottle. Then the remaining wine could be good for upwards of a week.

Answer 8

2 weeks if the cork gets put back in
