Rauchbiers are interesting but not my thing. Subtle smoke is fine but smoke is the main flavor profile of them which doesn't appeal to me. A local brewery did a stout with a small portion of the grist being smoked and it was glorious. They also split the batch into 3s and did a third is freshly emptied bourbon barrels, another third in bourbon barrels that housed maple syrup, and the last third in bourbon barrels that housed honey. It is a top 3 all time beer for me. Incredibly complex and delicious.
