Mold, it would not leave that tobacco with those sweet honey colors. It looks great...............2019 tin of Stonehenge has this on a few of the Flakes. Looks like ice crystals so I'm assuming sugar?
I think it crystals as it smells like sweet hay and floral of a Virginia. Forgive my camera but it looks like ice formed on the leaves. No sour or funk smell at all. Now the bigger issue is something is wrong with my palate as thus is about the 15th good quality Virginia I've tried and I think I'm done with them. They are taste like sucking cardboard to me. I've tried Capstan, orlik, escudo, navy rolls, Stonehenge and many more. They are meh to me. I wanted to be a Virginia guy so bad lol.
I did smoke a bunch of it. It tastes just like sucking on a cardboard tube. Nothing, no taste other than burning paper. Like I said my palate cannot stand Virginia's I guess.Seriously, taste it. You'll get sweet or antibiotic. You won't die.
