I have to admit that I like my cigars newer. I've smoked a number of aged nc's and they don't compare to their reasonably fresh counterpart.
I like some firepower in my cigar though.
I can see where aging cigars to take some kick out of them would allow more people to enjoy them, and that's cool. But to say it makes them better? I'd agree with milder, but not so much "better".
I do buy wholeheartedly into letting a cigar settle after it's been shipped, although if it's been only a day and came half way across the state, I'll smoke one from a box as soon as they arrive. If they've been in the air, I'll give them at least a week in the humi before I touch them.
I'll also admit that I use the "aging" method to take some whallop out of cigars that are too overbearing for me. A month in a tray in my humi and a little air will tame a stick that I don't care for and make it very smokable.
A lot of new, less expensive cigars arrive wet and full of ammonia. Whereas they're totally gross right off the truck, a week or maybe a month or two will make them smoke beautifully.
The same cigar after a year is likely to be far more mellow, possibly to a point where I don't care for it anymore, but someone who doesn't like as bold a cigar may love it.
And the time will definately bring out certain nuances that were likely overpowered when they were young.
So, I think "better" is probably a poor description, and somewhat misleading.
Tamer, milder, older, more delicate, all those are probably a better fit.
Cool thing is that it's a tool that can be used to make the incredible array of cigar flavors out there even that much more vast. It's fun, and it's a nice addition to the hobby.
The cnobbery that surrounds "aging" is somewhat offputting, but it's going to remain. I just hope I can appreciate it for what it is rather than insisting it's somehow "better than".
