tip number one from my new thread
when storing pot . . . never ever use large glass jars. use smaller jars that do not allow any "empty space" between lid and pot. this will cause mold to set in and start. stopping mold is one of the biggest problems to storing pot. like beer, do not expose to light, and make sure your lids caps are not dirty or worn around the inside ring. the last thing you want is a breathable storage container, which will dry it out.
