How long will crushed grains stay fresh?

[cleone]

I have some left over crushed grains from my last batch. How long can I expect crushed grains to stay fresh? I have heard about two weeks, but I am storing them in my garage @ 40F.

Is the container air tight? Cracked grains can absorb moisture as well as off flavors. I too have heard the two week time line and have never challenged it. My brother and I bought a mill so we crack only what we need the night before brew day. I know I am not much help in the matter but know that your enemies are moisture and odor absorption.

They are being stored in airtight plastic bags and all inside a plastic cooler. I guess with the price of grains, as you say, why challenge it . . .

Thanks for the feedback

I justed order some grain online for two batches and I will be brewing them back to back. The guy at the brew store told me if I start the second batch within a few weeks he would go ahead and crack the grain for me.
