Smoking some barley

Elle and I are planning to make some beer, perhaps this coming weekend. I thought I'd smoke some barley with madrone, to see how that works. I'd like to try making some whiskey, so this is the first step towards that. Next I'd like to malt some barley, then use the smoke to dry it. Perhaps I could use Joels coffee roaster, if he'd let me? Actually, I think the fire pit would work better. I was trying to look into whether there are any peet bogs in existence in the northwest. It seems likely. I think hardwoods and fruitwoods could suffice though.
