Is it better to age and/or cellar tobacco in their original sealed tins or to put the tobacco into a mason jar for aging and/or cellaring?
From what I understand part of the aging process/mellowing of flavors when aging tobacco is to the consumption/lack of oxygen within the container. I would assume then that opening a sealed tin would reintroduce oxygen and disrupt the aging process. However Ive heard people suggest immediately opening tins and storing the tobacco in a mason jar. I would love to get some opinions on the matter, and as always appreciate the feedback.
It all depends on how long you want to age tobacco, and what kind of tin they're in.
If you're thinking of 10 years or more, think jars or food grade .7 mil Mylar heat sealed bags. Less than that, most tins will hold up, though the square and rectangular tins are more susceptible to seal failure than canister, or round tins.
Greg Pease was a major proponent for keeping blends in the tin, but changed his mind several years ago after finding "disappointing failures" in his cellar, and he's been cellaring since the 1980's. He now advocates tansferring to jars for aging.
C&D tins from the early 2000's of a number of Pease' blends, failed by rotting out from the inside. I've published images of this on this forum. McClelland, who used much higher food grade tins for their product are now showing problems with their 1990's tins.
I've experience a number on tin failures from tins older than a decade, including one canister Rattray's tin from 1996, that failed along the scoring line for the pop top.
Anything I want to keep for long term goes into jars or Mylar, and shorter term stuff can remain in tins.
Also, I wouldn't worry to much about the "aging interruption". Once transferred the process starts up again. And aging isn't a guarantee of anything in terms of whether or not the tobacco will taste better. That's a myth. Tobaccos
change during aging, more of less, and whether that change is an improvement is up to the individual smoker to decide, not the hive mind.
