Smoking your own malts gives you another knob to turn on the process side.
Jeff has experience and a system that one can only envy for smoking grains. The wood that I can add to his list is pear, that has some nice soft smoke flavors and even goes well with some hops if you use some restraint on the smoke and hops.
I have some crabapple shavings to try out soon.
Why not pour in a 1/2 bottle of Lagavulin if that's what you're after?
