On an impulse last week I picked up some German Merkur and Herkules hops from the LHBS to use as flavoring and aroma hops in a pilsner, because I thought they might be an interesting twist. But now I'm not sure if they will really fit the style, or even the style of a "light lager", since they're described as primarily bittering with some dual-use on the hop reference sites I've found for merkur and a conference poster comparing them.
Has anyone had experience using them for their aroma? Or using them at all?
Both have an AA of around 13-14, which is high for flavoring and aroma schedules, but the labels claim they're good for all parts of the schedule for pilsners. I haven't experimented, but have noticed (and also been told) that you can get a fair amount of bitterness from even a 25 or 30 minute boil, despite conventional knowledge. Does it sound like I might get appropriate bitterness if I left out a bittering hop and threw one of them in around 30 minutes, and the other around 5? And more importantly, which one should be used for each step? I could just open them both and choose after smelling them on brew day, if no one has recommendations.
