What's the shelf life on crushed specialty grains?
3 weeks, maybe longer of you keep them in humidity free environment.
buy yourself a half pound of crystal 60L. Tatse it each day for a few weeks. The crisp crunch will fade soon as the grain sucks up moisture.
I think if you keep them dry, like in a big rubbermaid container, they should be good for a few months. It's best to keep them uncrushed, and then crush when needed.
