I would store it in a zip lock bag with a wet sponge and check it every 3 months and dehumidify it as needed, not sure how long the shelf life would be.
Good info, thanks!This is my third year of growing & processing my own tobacco. It needs to be dry to store or it will rot, even if its cured. After hanging till it browns, I shred it then run threw an old dehydrator then into ziplock freezer bags or vacsealed in mason jars. Easiest way I found to bring the humidity back up for rolling & smoking is a pan of water with a colander ontop & tobacco in the colander. Just reach your hand in it about once an hour & stir it around till you get the humidity in it you want.
