This question has a few answers.
With your everday table wine:
If the bottle is unopened and on it's side, it will last quite a while. It won't spoil. The problem will be that the overall quality of wine will be comprimised. Wine is made to be kept at specific temperatures to remain healthy.
If the bottle is opened, it'll last a few days, but the quality will definitely be severly comprmised, if not totally unpalatable.
Everything also depends on the wine..
As far as the fine wines, don't put a bottle over $30 in the fridge.
An opened bottle of white wine will stay fresh in the fridge for at least several months, and sometimes for years.
However it's best to seal it or even cover the lid. Oxygen in the fridge will convert the alcohol into carboxylic acid, basically turning your expensive wine into expensive vinegar.
Although this takes some time (roughly 2 weeks open at room temp, it may last a lot longer in the fridge.) this process starts as soon as the bottle has been opened. Over night you may only notice a slight change in taste, apart from that the wine is perfectly safe to drink or even better cook with.
Not with you . . . it may be possible to take it in your luggage, but the baggage inspectors are going to want to sniff it and test it to make sure that the champagne is not an explosive.
Any airline in the World does not permit you to do this legally.
Take a full bottle of thums up and chill dude.................
The traditional long stemmed champagne flute holds 6 ounces to the rim. The normal serving would be 3 ounces as they are never filled completely to the top for toasts. To figure the answer we take 25.4 and divide that by 3: 25.4 ÷ 3 = 8.47 glasses. Since we cannot fill a glass with .47 of an ounce the answer is 8 glasses would be the yield for that volume of champagne bottle.
Bout 7 minutes when it's in ice, longer in the fridge.
About 20. A "regular" wine or champagne bottle is 750 ml, which is a bit over 25 ounces, and a typical "toasting" -sized pour is about 5 ounces, so figure five servings per bottle.
it takes thousands of years for a water bottle to decompose.
