I do partial mash brewing. Three weeks ago I picked up a recipe (Irish stout) and have not had a chance to brew it. The cracked grains have been sitting in my closet and this morning I noticed they no longer have that yummy smell they had at first.

Do cracked grains go stale? Will the delay affect the taste of the beer?

Crush grain lasts like 2-3 days. In a fridge you can probably eek out a week or two tops. Grain is cheap, I would dispose of them.

Definitely get new grain. No sense in going through all that effort and getting a sh*tty beer over a few bucks worth of grain.

Chew a pinch. If they taste stale, toss them. Three weeks at room temps is pushing it.

[Could always make some Old Brittle Root Stale Pale Ale. Look on a Pogo website for the recipe. I know, I'm old.]

Thanks for the help! I'll head back to my LHBS rather than take a chance.
