I'm a little baffled by this whole layering process for black & tans. The guinness goes on top and floats because it is less dense than the pale ale (I get that part, but have never successfully layered). Supposedly, guinness extra stout doesn't work, but I've heard that draught & extra stout have relatively the same specific gravity. Why wouldn't extra stout work? Somebody please explain. A friend and I have been arguing about this process and I don't believe that it's impossible to layer guinness extra stout.
