I've heard you guys say that rectangle tins should be opened and jarred as they don't seal as well. Is this true with every tobacco. S.G. Full Virginia Flake for example or F&T Cut Virginia Plug come in the rectangular tins. Do I need to open all of them and jar them? Would it be better to just age all together in jars? What do you guys think? What are you experiences? I've got about 30 tins of CVP for example should I open and jar them all? Thoughts?
