An Anecdote, when I was younger, me and a few colleagues got into whiskey and had somewhat regular meetings. One time I had 2 bottles I got for Christmas. Same distillery, one 12yo, the other 24yo. We all liked both of them, but also all had the feeling that the 24yo offered more than we could actually get out of it. When I had it again a few years later, I could appreciate it much more.
