I have a one pound bag of HH Old Dark Fired on its way, my question is, what's the best way to store this for long term? I will fill a jar for smokin now, but want the rest to have a nice resting place that will keep the baccy good. Mason jars? Do I stomp them tight? Vacuum seal the jars? Vacuum sealed baggies? Loose in a mason jar and no vacuum? Help me out, what's the best way to preserve it. All I have used up to now is tins and once opened, I jar the balance of my first smoke. Thanks in advance for your help.
