I made a 4 gal. Schwarzbier and dry hopped for 1 week with .75 oz. It came out sooooo good! Not overwhelming, but just enough to add some complexity. Not bitter and a slight oakiness. Next time, I might bump it up to a full ounce.
I got some too and I'm trying to figure out what to do with them. I've been enjoying a barrel aged Schwarzbier lately. I'm thinking of making one and dry hopping it with these. Just not sure the oak will come through.
