Good responses here. +1 that it doesn't get better with age once it's in the bottle.
If you're going to have a rotation with some bottles that are bound to be opened but unfinished for a long time, it might be a good idea to spray a little wine preserving gas in the bottle (it's cheap and I think it works) and periodically examine the corks for signs of decay. Also, never store a bottle on its side, even if it's unopened.
I had a bottle of Dalmore where the cork went bad because I moved and the bottle somehow got stuck in an odd box of 'junk' that went to storage. It sat for five years before I needed something in the box and found it. The cork was dried out, but the bottle didn't appear to have lost any liquid, so I still drank it. It was definitely a bit less yummy than a fresh bottle and it had little cork sea monkeys swirling around in it, but it was still reasonably tasty and drinkable. Obviously not something to give to guests.
Is this your homework, Larry?
