I posted this on another thread that was discussing the same things...
http://pipesmagazine.com/forums/topic/research-biologist-meets-tobacco-bloom
It wasn’t a post by Sykes, but he had commented on the thread. That’s how I was able to look it up again, especially since the thread is about bloom.
But Jmatt had posted some further information about the reintroduction of oxygen.
However, the topic is rehashed over and over in many other threads, and even in Greg’s articles on the magazine portion of the website.
The arguments usually have someone or multiple posters with supporting evidence that reintroducing oxygen rapidly speeds up the “rotting” (for lack of a better word), and then just as many people will post that they constantly reopen their tobacco jars to pull smokes out of it, with no harm to the tobacco. Which is countered by the argument that if a tin is opened after a few years and put in a jar, then the said jar is reopened constantly, then actual anaerobic aging has never taken place, which is also supported by reports on homegrowers forums. Those jars wont see rapid degeneration of the tobacco, because it is merely held in a statsis of storage, never fermented, but yet a different type of aging.
Basically, do you want the sweeter aging process that creates bloom, or do you want the less predictable aging process? Or, does it matter to you?
None of this is my research, but explains what I see sometimes when dealing with jarred or aged tins.
