We bought my father
a 60-year-old bottle for his 60th. The merchant warned my brother it might be undrinkable. At £250 a bottle. We only bought it on the assurance that if it was revolting he's give us another, younger but guaranteed to be drinkable, bottle.

Luckily for them it was actually fine. Unlike young wines, when you open a bottle that old you have to drink the lot within a minute or two as the air makes the flavour collapse almost immediately. It was actually jolly nice.
