I compost everything I can and have a very successful compost bin. But I do NOT put my spent grains in there. Any "green" materials (like spent grains, perhaps counterintuitively), in the presence of moisture and lacking aeration, will rot and stink. Few things smell as bad as spent grains when they are allowed to do this. This isn't composting (aerobic), it's rotting (lots of anaerobics). It's really hard to keep spent grains from doing this in the compost pile, and I don't want those nasties in my compost. The stuff works great, though, when spread evenly on the lawn and raked in. Five to ten minutes and it's done.
