Add me to the "Food Saver and Mason Jar" crowd. I sometimes split them between two pint jars if it is something I don't use a lot of like Warrior. It makes me feel like half of the hops will last longer and won't be exposed to oxygen when I open the jar for 1 ounce. They don't take much more room but you need more of them.
A free deep freezer works wonders for hop storage too. The top shelf has a few 12-16 ounce packs(Sorachi Ace, Summit, Citra, Jaryllo, Cascade, Centennial, Magnum, Mosaic, Sterling, Pride of Ringwood, Galena to name a few) along with a few smaller packages of hops saved over.
I also can't find a way to seal the mylar bags however youtube food preppers have a way. Some use a straw and a flat iron while others put them into a vacuum seal bag which works. Others buy the special sealer.
