here is a topic that is frequently batted around the cigar community ballpark. the white areas that appear on cigars at times; is that mold or plume(bloom)? the bro-science surrounding this topic is seemingly endless and quite often...incorrect. lets define each and discuss why each develops on those lovely and often expensive sticks. mold is mold. its simply a product of poor storage conditions, generally too much humidity in your humidor over a period of time. when excessive moisture exists on an object, bacterial fungus is produced. if these bacterial spores are not removed in some fashion eventually mold with begin to appear. now mold on the wrapper isn't a deal breaker. generally, exterior mold can be wiped away and the cigar smoked--though i wouldn't. the spores that spawned the mold are still there, and toxic, after all. mold on the foot, in the filler leaf, definitely destined that prized smoke to the trash. foot mold means possible mold through the interior of the cigar, and that mold cannot be wiped away. conversely, plume is a reason to celebrate! it shows your cigar has been stored properly over an extended period of time and the leaf has aged properly and is at the height of its goodliness. cigar smoker's nirvana! plume, or bloom, as its sometimes referred to, is a natural process of leaf maturation. as a cigar ages properly, the oils, oleoresins; slowly, migrate to the outside of the cigar. once there they eventually crystalize and become visible as a white powdery substance on the wrapper--plume! plume can be wiped off before the cigar is smoked, or not. either way, a cigar with plume is a treat to smoke. as a rule, mold appears fibrous. it can be described as downey or furry. plume, on the other hand appears crystalline, like tiny salt granules. cigar bro-science is full of misinformation on this subject. "if its white, its plume". wrong. mold comes in many different colors, blue, green, black and, yes, white. "if it wipes away easily its gotta be plume". nope. it is true plume will wipe away easily, however mold will also wipe away easily if it has recently formed. so now you know.
