So I picked up a CAO Brazillia in a metal tube today and when I opened it, there was white stuff on the cigar... It seemed almost like a powder or ash... I'm afraid it might have been a mold or something. Anyone have any idea what it may have been? Also, when putting sticks in a humidor, is it best to take them out of all packaging or leave them in? Does it make a difference if its cello vs. metal?
