personally, I've never understood why Opus and Anejo are the only NCs I hear about people aging. seriously, what makes them any different? They're supposedly made with tobacco that is already aged anyway. I don't see why any other premium NC wouldn't also improve with age.
and as far as CCs go, I think the traditional wisdom is that they need more time because they are made with very fresh tobacco, however I believe Habanos has been aging their tobacco for some time now.
That's not to say cigars, especially CCs, don't get better with age. They certainly do. It's also a matter of preference though. They gain a lot of smoothness and complexity with 6+ years but they can also lose a lot of strength. I've only smoked a handful of aged CCs, but i was really surprised at how mild they were.
