Just curious - have you gone full blown double blind on this? Age half a box vac sealed 7 years/half a box exposed 7 years?
As a matter of fact, yes. I have done this many times. I have placed half of a new box in a sealed baggie for aging, while smoking the rest. In every case, after finishing those cigars that were aged for several or more years without being sealed, then opening the baggie, those aged in the baggie were superior in terms of their physical integrity and even more so, in depth of flavor. No question whatsoever. Most recent example: Por Larranaga Robustos PCC.
By the way, I learned of this method from discussions of Min Ron Nee.
