Know thy malts! Or not ...

[1974Alby]

if they float and still have some crunch and crispness on the tongue they are fresh and friable - good! If they sink like a stone and chew up like old stale bread in the bin mate.

I never knew that but sounds like a great tip that I will put to use as I have some grains that are getting a little long in the tooth. does it hold true for rye grains?.
