FWIW, one of the foremost evangelists on the benefits of aging, as well as one of the foremost proponents of aging in the tin, as well as being one of the foremost blenders in the field, a fellow by the name of Greg Pease, recently changed his recommendation for long term aging from keeping the tobacco in its tin, to jarring it as soon as possible and then letting it age in the jar. Too many disappointments popping up in his cellar.
The difference in part is that he's an actual long term cellerer, with contents going back decades, while most of us are relatively recent practitioners with few, if any, tins older than, say, 20 years and few tins even 10 to 15 years of age. So if I'm going to be giving suggestions consideration, I'm more inclined to go with someone with actual long term experience.
And I'm ignoring the poll, since it lacks a "both" option, and is therefore useless.
