On many websites and in cigar forums I read about "PLUME" or "BLOOM" in cigars. This is a white powder looking substance caused by the oils in a cigar when it ages. I never really see any pictures that show this effect clearly, so I thought that I would supply one here so that it can be seen properly. Some may confuse this with mold, but mold may be green-ish or blue-ish. Plume does not have a smell and can be easily wiped off of the cigar without leaving a stain, like mold would do.
Here is an image from a couple of my San Cristobal Cubans from May of 2001 to show what real plume looks like:

I'm sure some of you will tell me that it really is mold and that I should send these sticks to you for "testing", so a "thanks but no" in advance may be in order, lol
