I have a friend who has challenged me to come up with a German dark beer that will take him mentally back to Germany. We talked about a doppelbock, schwarzbier, dunkel, etc. I have only brewed typical ales but with the cooler weather coming my basement stays at about 60 or with a window open I can drop it down for a cooler fermentation. I don't have anything to truly hold a lower fermentation temp so I was wondering what recommendations can get tossed this way.
Thanks!
