I haven't done it yet but will be soon. My plan is to smoke as cool as I can, spritzing the grains periodically with water to keep them moist but not wet and turning the grains once in a while. I plan to use Alder. Others report using pear, apple, cherry, beechwood, etc... Not hickory. Too harsh & tastes like bacon. Not sure why that's bad but ??? Beers to smoke? I'm planning a Porter & will smoke 1/2 the base grains. Weizenbock is another one. Hopefully others will pipe in with more spscific info.
