I really like this Malt - somewhat similar to Pale Chocolate, but with perhaps a bit more acrid, fruity roastiness (this is just from chewing the grain raw, side-by-side). I use 5-6 oz in my big, sticky Old Ale and it adds a nice whisper of roast and deepens the dark ruby color.
I'm brewing a Porter this weekend or next and will augment the Roasted and Chocolate Malts with ~6oz of the Kilned Coffee. I'm expecting good things.
