I sure don't get it. Although there are significant differences between bourbon, American whiskeys and Scotch, I just don't see why you would feel the need to smoke bourbon. It seems like an attempt to do something just to be able to do it. The great thing about Maker's Mark is that it is clean, light and sweet. Now, I could see someone doing a small batch whiskey with smoked malt, that might have the same benefit as a rauchbier.
I'm feeling bearish, and I'm packing a Wusthof Grand Brisket slicer from MABA
