What can anyone here share about their experience with Brauerei Wolf (Rüdenhausen)?  They appear to be a very small brewery (beers: pils, dunkel and heller bock) in Unterfranken who cultivates their own grain and I'd like to look into a visit one of these days when back in the area.  Has anyone been to the keller fest in August and know what that might encompass?  Anyone spent an overnight at their inn?  Thanks for any info!
