If anything would survive time it would be Russian Imperial Stout as it has a high alcohol content but the real test is the sniff a taste test i.e if it smell ok looks ok it probably is but me I would keep it for a talking point or bar ornament
I don't know how many bottles you have, but before opening, you may get want to check out its value on eBay; so wof these unopened bottles sell for decent money
If you do open it, try harvesting and culturing up the yeast and maybe send a sample to these guys. Could be fun checking the Internet for a recipe and doing a brew of it.
