I know it is recommended to buy tins or store your tobacco in mason jars, I have a really good sealing latch style glass jar I use for my opened stuff. But due to cost, I sometimes purchase pouches of tobacco but not far in advance. I was wondering if pouch tobacco unopened will still last a couple or few years, that is being stored in somewhat cool areas . . .
I know its been asked already somewhat, but I couldn't find a direct answer to unopened pouches.
