I'm not advocating that anyone leave their tobacco in an opened tin for a year. But if I'm going to open a tin with the intent of smoking it down, the couple of weeks to a month aren't going to hurt anything, and I live in SoCal, in a very dry climate. Carrying a tin in my pocket is much more comfortable than carrying a jar.
As for leaving tobacco in an opened canister for a year, both of those were accidents. I'd opened up a tin of Rattray's HOTW and absentmindedly put it back in the closet. A year or so later, I reached for that tin, thinking it was unopened stock and was surprised that it was opened. Turned out the seal was good enough on that tin that the tobacco was at the perfect moisture for smoking. Same thing with the other tin I'd put back on the shelf. If that had a been a C&D tin it would have been mummy dust.
I'm fascinated that people want to keep the tin moist, and then dry it out before each smoke. It's an extreme waste of time, IMO.
Bingo. I like this blend. I don't like that blend. I only like about 5 blends. I don't like anything else, and don't care to try anything new these days.Frankly, the HOTW was spectacular. This essential oil thing is something I haven't quite wrapped my head about. I recall hearing from people who process tobacco that a some point the leaves are thoroughly dried out, so that being the case, what happened to all those essential oils then?
I don't have jimink's palate for tobacco and his ability to discern the subtlest flavor is the real deal, which is why blenders send him samples of blends in development, for his critique.
I do have enough of a palate that I can accurately figure out ingredients in a dish by tasting it, except for ingredients of which I am unfamiliar. And when in the mood to focus, I can pick out a lot of nuance in the blends that I smoke.
Do we perhaps overthink all of this? Shouldn't it be more like, "I like this blend" or "I don't like this blend" and leave it at that? Only if we feel motivated should the quest to get the most out of the experience become part of the experience? Maybe sometimes ignorance is bliss?.
