It is debatable whether plume actually contributes to the enhancement of a cigar, or if it is merely an indicator of a well aged cigar stored under optimal conditions.
Thanks for explanation!

My one question - do we expect plume to develop on an entire box of the same cigar, stored under the same conditions? Or would we see it on only one or a handful of cigars out of the same box? Curious if it's so rare that even all cigars in the same box won't develop plume.

I've never seen it in real life myself, of course.
