I read some pipe smoker boards where they store the tobacco in canning jars to age it. They had a good seal and kept it in a cool dark location.
Glass jars would be costly because of the money involved, the weight, and the number I would need to store it all.
I already filled one plastic container (abt 1 1/2 gallons) and am through about a third of the bag, so we’re talking some serious volume.
After the apocalypse?
A pack of smokes will cost you a gallon of gas!
