The recent production LP9 I smoked surprised me with a lot of floral potpourri notes, but I'm pretty sure those are the first flavors to go with aging, or improper storage...
My theory, the old LP9s were a different stick, the flavors were brought out with aged quality tobacco. I think the new LP9s are trying to recreate a similar complex but strong cigar, but going about it by different means. I don't think they're doing any infusions or anything, but that the tobacco they are using brings a lot of big notes that dissipate with age, whereas the old formula used tobacco that had bold flavors that age brought out.
