124-year-old Hennessy Cognac

[Thraz]

It's possible for cognac to last that long. Well, in theory anyway - I can only wish I knew first hand. If it were me, I would open it and smell it. If it's good, great. If it has turned you should know right away, and then you have two options: seal it back with the cognac still in it (with the original cap and maybe some wax), and you will still have the legacy from your great-grandparents; or pour it down the drain, clean the bottle and buy some good cognac to pour into the old bottle. You can use the old bottle as a vessel for cognac in your home for ever and let the legacy live on. The best case scenario of course: the cognac is still good, you drink it and then use the bottle for new stuff.
