Ok, I've bought a flat of 16oz wide mouth Ball canning jars. I'm keeping a few out to keep my every day rotation in, but I feel like I should start cellaring in case new smoking legistation ends my new hobby before I even get started. So how much baccy should fit in a 16oz jar? I know the basic formulae is "oz of tobacco x 4 = ounces needed in container, but 2oz seems to be way too much for an eight oz canning jar. Should you gravity feed like I have been doing, or pack nice and tight? I've read a lot of cellaring threads on the forum but none really touch on how tightly to pack it for long term storage. Sorry for all the new threads here lately, but I'm really getting excited about this, I just wish I'd picked up pipe smoking a couple of years earlier!  darn autocorrect!
