Not the same as moldy rye bread, huh? So, if it tastes sweet, it is good and it you see purple elephants flying around the room after tasting, it isn't great? Might be valuable though.

If all of the discussion a year back from the Carolina Red Flake mold outbreak taught us nothing ...
It’s mold. Toss it, unless you want to roll the dice. Scraping off the white parts still leaves microscopic spores that could be inhaled before th tobacco combusts. Jiminks wrote a few good posts about this.

If you shine a flashlight on it is it reflective - like shiny and sparkly? I have some Blackpool with definite crystals that sparkle when the light hits it right.

Just tried that. Didn't use a flashlight, but the kitchen overhead light and a 10x magnifier. I saw individual, sugar-like crystals that sparkled.

A few years back, a member here took so microscopic images of crystals that had formed on Stonehaven. I found these through a link from an article on the Dutch Pipe Smoker blog:

Very cool! I wish I had a microscope.
I was able once to take photos of individual snowflakes with my macro lens and tubes, but these crystals are just too tiny, methinks.
I used the 10x jeweller's magnifier to inspect other tobaccos I have here. A fresh tin of EMP that came in last Friday from 4noggins, and a house blend from my B&M. Interestingly, they all have sparkling crystals on them leaves: they're just too tiny to notice with the naked eye, unless they're clustered as bloom.
You learn new stuff every day...

Trying to keep up...are sparkling crystals assumed to be some sort of mold or fungus as well, or is there no conclusion as of yet?

so basically that link to the friendsofhabanos.com people, state that there is no such thing as plume, but a large variety of mold. Interesting to know ...

Lab results aren’t opinions. No one needs to “buy” anything. Researching the subject is easy and copious amounts of info are a keystroke away.
Many of the samples provided to the lab in the link above were heavy with what looked like sugar crystals. When analyzed none of the crystals contained sugars. The question isn’t which white substance is sugar, it’s which species of mold is least likely to cause harm.

The major volatile organic compounds were erythritol, l¬threitol, xylitol and dl¬threitol and a small quantity of alkanes. It was concluded that the bloom of cigar leaf was a kind of mixture composed of KNO3, NH4Cl, as major constituents, and some volatile organic compounds.
Potassium nitrate, ammonium chloride, and:
Erythritol, a polyol (sugar alcohol), is currently used as a bulk sweetener in reduced calorie foods.
A four-carbon sugar that is found in algae, fungi, and lichens. It is twice as sweet as sucrose and can be used as a coronary vasodilator.
https://pubchem.ncbi.nlm.nih.gov/compound/l-Threitol
Xylitol is a naturally occurring alcohol found in most plant material, including many fruits and vegetables.
Interesting. I wonder what they would find on other blends than cigar leaf, how they selected samples and how widely representative they were, that sort of thing.

"There are no facts, only interpretations." Nearly infinite wisdom in that statement.
Well, coming from a family of scientists and engineers, I'd have to take issue with this. It will certainly give comfort to those who never want to face anything.
But I do believe that the following is valid:
"Facts aren't always answers."

Yes, the "how harmful" question then is the important one.
I've opened tins many times fresh out of the mail from online retailers to see the contents inside sparkling. Very interesting!

Thanks for posting a link to the pics sablebrush52. Here is the thread they were in http://pipesmagazine.com/forums/topic/stonehaven-bloom-under-the-microscope
I tend to agree with yaddy306, they don't look like sugar crystals. They do look somewhat like potassium nitrate which is sometimes used as a fertilizer when tobacco starts growing, as opposed to a preplanting application.

Since everyone here is guessing at answers without the benefit of factual information, I guess that I'll join right in:
It's not tobacco.
Could be mold of some sort.

Could be bacteria of some sort.

Could be something else of some sort.

Could be toxic.

Could be non-toxic.
Send it to a qualified lab if you want real answers.
