Which of these malted rye grains?

Strictly speaking, none of them.  Red malt is significantly darker than crystal/caramel and lighter than roasted/chocolate malt which tastes like cinders.  In practice, however, crystal will do just fine.

That's what crystal looks like compared to real red:

 

Crystal looks red and I would have chosen that as red rye malt from the photo but You have said it is a lighter malt so it must be vice versa. So red is REALLY red - dark red.

Will be interesting to work with. I'll buy crystal and continue my search for the real thing.

Thanks Suave. Good comparison.

If I buy the crystal how do they come? Do I have to dry and grind them or do they come ready to grind?

One last question. Just went to order and it asks if I want them "crushed" or "whole". What do you advise?
