Extensive Aging and the Milder Cigar...

I can't speak as much on "extensive aging," but I know from experience that more moderate age (2-5 years) can add a tremendous amount of flavor to a milder cigar. In fact, I'm willing to state for the record that I think the idea that milder cigars don't age well is a myth. The change may not be as dramatic as with a cigar that started out very spicey, but it can be great.

Just for one example, my Tobacco Baez from 2-years-ago (admittedly not a lot of age/rest) are getting significantly better than the fresh ones I've had. They are actually MORE spicy and have a lot more flavor.

I also have some CAO Gold from 2002/3, and those are also much nice imvho than they are new. They may have lost a bit of nuance, but they buttery core on those is just awesome.
