I think PJ is right.
If you look at it from a logical point of view, you have the following options:
--> you drink the bottles eventually (rather sooner that later, you never know what happens...)
--> sell or swap the bottles or give them away as presents (don't forget the one who gives you this good advise if you should decide for the last option )
--> die before you opened the bottles or gave them away. I'm sure you heirs 'll raise their glases on you.
