I jarred up various tobaccos and noticed when I came to open them they had developed quite a vacuum. I'm assuming a bacterial process is using oxygen and hence reducing internal air volume. Does anyone know any different? Or is able to correct my thinking ?

Yep. Oxygen is consumed until the processes turn anaerobic, and if there is enough tobacco present, the resulting environment is negative pressure vs. atmospheric. Enjoy! That means it’s been aged for more than a short period!
I've found that jarred Virginias tend to swell up. The lids sort of pop outward.
I think there are a lot of variables. For many of us the initial vacuum is created by temperature changes from when the jar was packed, which most likely cooled by several degrees. It’s also possible that activity that might cause bulging on a tin actually forces air out past the seal of the lid. The ring is not necessarily situated to prevent that entirely.
There are definitely some that suck....Granger comes to mindSome tobaccos swell and some suck.
Yes it actually should be able to let air/gas out but not in I believe
Thew vacuum develops at some point after tightening the lid. The button at the center of the lid depresses. But then for some reason with some jars it releases with a loud "ping." I used to go to sleep thinking that my jars were singing, and since I was the only person home, that they were singing to me.
I began to posit an alien infestation, and then I began to search for their scat, as it is held universally true that even aliens poop. More later.

Shites. And I thought it was all a magic. Tobacco fairies and all that, you know..
I have great memories of opening cutter top tobaccos with bulging tops. The "Psssssst' sound they make is the finest music you have ever heard.
Me too. I store my tobacco in an old Electrolux. The residual dog hair reminds me of Granger.
Another some do neither. I think that covers all the possibilities. ?Some tobaccos swell and some suck.
just like peopleSome tobaccos swell and some suck.
hence we are tobacco.
