6 ~ What are these crystals on my aged tobacco?
Answer: nobody really knows. But Greg Pease has some thoughts...
The crystals that appear on aging tobaccos are more likely something that is soluble within a narrow pH range. These crystals are not very soluble in water. As the tobacco ages, the pH changes, and some things that had previously been in solution may, and apparently do, precipitate out. But, from some very preliminary testing, it is almost certainly not sugar.

I don't think the crystals that form on tobacco are sugar. A long time ago, I did some messing around with some of the crystals I discovered in a tin of Virginia, a little analysis, and they did not behave like any sugar that would be in tobacco. They were not even soluble in water! At the time, I could neither harvest enough of them, nor did I have access to the necessary equipment to get a read on what they might be.
