Here's the last one I did. I took the recipe Denny posted from the Uerige brewer (which was given in amounts, not %) and scaled it for % in software. Makes a pretty nice beer. Simple and good.
1.5% Carafa III
19.9 IBU HM - 60 min
15.1 IBU Perle - 60 min
14.7 IU Spalt - 20 min
WY1007 - hold @ 60F for 3 days, slowly ramp to 68F
Mash 150/ 75 mins
Amber Bitter water profile/ 5.4 mash pH
That looks good. 50IBU slightly on the high side for me but I like the simplicity of it.
I agree that I like how simple the recipe is. I am putting it in beersmith now but taking the IBU down a notch. Did you end up making this? (granted this is an older post). All Dusseldorf recipes I find are full of a crap load of malts. Seems kind of odd. I got one from a head brewer last year that was just 2 malts. Pils and then Carafa III.
That looks like the Zum Übrige recipe that was published by the brewer. I have some Alt yeast, need to brew that. When I was last at Zum Übrige, I estimated it to be 50 or even 55ish IBU. Bitter for sure.
