For storing long term mason jars work great for bulk tobacco. Once I open a tin I put the tobacco in a small jar since I only smoke the tinned stuff occasionally (bring out the good china for guests, lol) but that's just me. I double ziploc bag the small amounts of loose stuff and smoke on it for up to a month, keeping that handful of baggies in an old humidor just to keep it all together. I don't have a large tobacco cellar and I smoke enough to keep my tobacco on hand down to a very manageable level so someone with more XP will have to weigh in if you need more info.
How are you liking your foray onto the pipe side of the tracks? Slumming it up with the rest of us, ha ha!
