What is the difference between mold and plume?
Mold can grow on cigars like it can on anything that is too moist. On a cigar, it is a greenish-grayish color that cannot be scraped off with your nail. Plume, or bloom, on the other hand, is a crystalline grayish white and looks like specks on a cigar. If you rub them or scrape them with your nail – they disappear. Plume is the natural byproduct of an aged cigar. Some of the cigars oils are secreted and create those lovely crystals – the sign of a very nicely kept cigar.
