I'm sure you'll find more here than you'll want to know about tobacco storage!
For me, it's simple: I buy all of my tobacco in tins, and it stays in the tin, aging (like wine), until I'm ready to smoke it. At that point, I pop open a tin and put the contents in a glass storage jar with a rubber seal and a metal-clamp lid (sold at Wal-Mart, etc.). Tobacco easily stays in smokeable condition in those jars for over a year. (That's the longest it's ever taken me to finish a single tin.) And using jars like this means you do NOT have to add any kind of humidity to keep the tobacco fresh.
For longer-term storage, I think most folks here who aren't buying tins would store their bulk tobaccos in sealed mason jars.
