Very interesting. Agreed on the varying opinions of the "all things cuban" dude and I'll not argue either side.

I will say that it get's pretty cold where I live, and I have taken many cigars on jaunts where the cigars in my possession experience large swings in temperature from their storage environment to their smoking environment.....and I have never seen this. Not saying it didn't happen, my experience just doesn't match yours.

A question I would have is, if the cause of plume is the rapid change in temperature of a cigar from it's storage environment to it's smoking environment, why is it so rarely observed? Certainly the situation you describe as creating the plume happens much more frequently than "perfect and stable" storage conditions.

I believe plume to indeed be crystallized oil that has "oozed" to the surface of the wrapper.

I concur with this, however, due to my understanding of the yaddy yaddy yah, plume is indeed evidence of proper storage of the cigar over time. I further believe this "time" to be an extended period of time.

I have not held this belief for quite some time now.
