I still have two or three sizes of the old band Blue Labels laying around. Unfortunately they're all mixed in with at least 150 others in my "NC bulk storage" humidor. I don't honestly know what's in there. It's where box remnants have been tossed for years now, and they aren't in trays. Just a big ol' mess of cigars.
I smoked an Imperiales about a month ago that I spotted near the top of the pile when I was recharging the Oasis. A few years did it some good, as the sharpness they initially had is more muted now. I picked up a distinct menthol taste. That was a characteristic they sometimes displayed fresh, but it seemed more pronounced now. Based on that one example, I'd say time is being kind to these.
Personally I've found cigars change with time regardless of whether they happen to be CC or NC. Some for the better, some not.
