Do you have a specific vacuum sealer you prefer using, i.e.-Food Saver, Pump N Seal, etc.? How long do you think herbs last in long term storage, vacuum sealed and stored in the refrigerator? Years? Months? I store my herbs in a mason jar, vacuum sealed with a Pump N Seal, and kept in the refrigerator. I also have a desicant pack in the mason jar, just in case. Opinions?
