No argument from me. All plume is mold per our forum. Now I know that as long as it has not invaded the foot of the cigar, a simple wipe should be good enough. This is where my topic comes in. Recently delving into the pipe world, those guys cant be convinced that plume is not a thing. My main concern, is if I do ever come across one of my sealed tins having crystals scattered throughout the tobacco, is it an automatic throw away? Most people that consider pipe tobacco as having plume are referring more to crystals that form on the tobacco, rather than the white powder.
