Ageing? What's that?
Most of the CC's I've had were relatively young (i.e. purchased and smoked OTT). Can't say I've had a bad one yet for the exception of an ocassional burn issue more than anything...which I guess they could be even better with age. :shrug: Actually, I do have a few brands still sitting around that I picked up 3+ years ago, but that's because I got the full box. Any splits I've done are ALL GONE!
I don't know what it is, but I can't keep 'em around long enough. My box of SCdlH El Principes are getting dangerously low (from a full box 4 years ago).
JL#2, RASS, Monte #2, PSD4, Boli RC, Boli Gold...ones I've had OTT that were good to exceptional. And those brands in another size would probably be just as delicious.
