As I was eating breakfast this morning, I was looking at the box for my 7 grain muesli cereal and got to wondering if anyone had positive experience brewing with unusual grains. Except for some wheat beers, the rest of my brews have relied upon a majority of malted barley for the grain bill. I’ve used small additions of malted wheat and rye, and unmalted wheat, rye, barley, corn, rice and oats. Just normal stuff.
Has anyone brewed with large amounts of more exotic grains? Spelt, buckwheat, quinoa, etc. or rare varieties of more common grains? How did it come out?
