I think this sounds right, 75% of the hops go in the bittering addition for a 60 minute minimum boil, 25% of the hops in the aroma addition, minimum 20 minute boil. If you taste altbier on tap in its hometown, you will not find a lot of hop flavor/aroma in it. The american tendancy is to add too much hops to everything, which I recommend avoiding when trying to clone a real dusseldorf alt. You are better off with the noble hops as well, if you want a copy of the original. Not to say the hopped up versions will taste bad. They will just be american versions.Here's the recipe for Zum Uerige from the brewmaster, via Denny, if you are interested:
Dr. Frank Hebmuller, who is the brew master and executive brewer at Zum Uerige:
Mittelfruh, Perle, or Spalt are the preferred hops. Aroma hop addition is about 25% of the total hop amount. Add aroma hops no earlier than 20 min. before flameout.

And to keep it interesting - American breweries swept the World Beer Cup in 2010 - Dusseldorf Alt category. IIRC, Germans were judging that category and were a bit surprised at what they chose.I think this sounds right, 75% of the hops go in the bittering addition for a 60 minute minimum boil, 25% of the hops in the aroma addition, minimum 20 minute boil.

Two interesting things from this recipe. 1 I really dig the krausening technique. I have never seen that before and it is intriguing and seemingly an effort to conform to Rheinheitsgebot. 2 If it was a Rheinheitsgebot thing, why did the brewer use gelatin?Found an interesting recipe , it might taste like Schumacher from the looks of it.

I'd be careful using roast barley in an Alt. I've made a few and the roasted barley had such a distinctive flavor that they ended up tasting like Irish Red Ales. They are interesting beers, and I kind of like them, but they didn't taste like Alts. I don't think German brewers would use roast barley, because it doesn't meet Reinheitsgebot.Ruhrpott Alt is:60% munich30% pilsner4% caramunich3% melanoidin2% roast barley1% carafa30IBU Spalt 60 minutes

I think it's gotta be malted barley.Barley is one of the ingredients permitted in the Reinheitsgebot, why would roast barley not meet it? Carafa is roast barley.
