Just factory sealed packages. They have been kept in a utility closet.
Some of them were packaged in plastic zip lock type packages. Kinda like the packages beef jerky comes in, except light can't penetrate.
Good to know about the jar storage. Thanks!!
Would it be beneficial to vacuum seal the jars? IIRC, there is some sort of gizmo you can get for Mason Jars. I have 48 pint size Ball Mason Jars. Would these work?
