Sealed, crushed grain. How long is it good for?

[Scriv]

I received a double order from Morebeer and I'm wondering how long a sealed bag of crushed grain is good for. I've read it's 6 weeks once it's opened, but what if it's not opened?

Likely a few months, if not more.

Sealed up in a low humidity environment - I bet 3 months would be okay.

I have 1.5 lbs of crushed C90 from NB that I got in Jan. Probably 6 weeks until I use it. I'm not concerned.

Good for a long, long time, even if crushed. It might not be as "fresh" but my palette couldn't tell a difference. Even base grain is good for a long time, though the proteins/enzymes degrade.
