My last rauchbier had a shot of Magnum at 60 minutes and Tettnang (at ~0.7 g/L = ~0.1 oz./gal) at 15 minutes. It's probably not traditional, but I think a little more hop aroma would add a nice complexity. So for my next rauch, I'm thinking about 1 g/L at 10 minutes. But which varietal? I've got a slew of German, Polish, Slovenian, Ukrainian, English, and old-worldy American hops on hand.
