Could you tell us more about the Czech Dark?
Czech Dark is like a German Schwarzbier, but with more roast and a complex malty profile. Here's the recipe for that version. It was BIAB full mash. I added some Sinamar because I wanted the color a little darker and the Eldeweiss hop blend is a blend of Saaz and other American grown noble hops sold by a BJCP Grand Master on ebay, his page is Hop Heaven. Edit: I do the beer with just all Czech Saaz hop now.
