There isn't any specific shelf-life for champagne...it varies due to the ingredients and makers. Champagne keeps for a few years as long as it is stored in a cool, dark, dry environment. Example: A bottle that has been on your shelf for 2 years will still be good for consumption. A bottle that has been in your closet for 8 years should be used only for cruise-liner christenings!
This depends upon how it is being stored after it has been opened. If the cork or something similar has not been placed to keep it fresh, probably 2-3 days at most. If you do have something to keep it fresh you are probably good for a couple of weeks or so. You can buy champagne keepers at a place like Bed Bath and Beyond or other places of this kind.
For years provided it is stored correctly and unopened. A bottle should be laid at a tilt to ensure the liquid is cork side down rather than sitting upright. As the cork ages, it would shrink if the liquid was not covering it therefore wasting the champagne. If it's not for immediate use and unopened then it should be stored in a cool, dry dark place such as a cellar. Bottles being checked for shrinkage of the cork or any other signs of air tight breakage. If a bottle is opened and being stored in a fridge probably a few days.
