Found a bin in the "junk room" and it had about 20 lbs. of pale malt in sealed plastic bags. It's at least 6 years old and has been stored in a plastic bin that kept it dark, dry and relatively cool in the summer and shows no signs of any kind of insect activity. Being a bit of a prepper, I know wheat and corn will last for years unground and sealed. Thought I'd ask some of you with more experience if you thought it was still good.
