I'd lose the caramunich and melanoidin and substitute them with 1.25 lbs more of munich.  I'd also cut your 20 min. hop addition in half.  Maybe bump up the Magnum to keep the same IBUs.  To be authentic, you want only the slightest hints of hop flavor, and aroma - if any at all.

According to the style guidelines, not that I'm a style nazi or anything, it specifies moderate to low noble hop flavor. I wonder if there is a way to assign an IBU% to the bitterness of a specific style of ale. For instance, "low to moderate" hop flavor could be 25%+or- of the total IBU's in the beer.

If one were to take the top ten examples from a given style and attribute average IBU's for bitterness, flavor and aroma. I don't think this data has been compiled in such a format but I believe it would be useful to know when creating recipes for a specific style of beer.

Ron, have you tried a Zum Uerige alt yet?  That will give you an idea of what the flavor profile is like.  To my recollection, the bitterness is quite high and it has a very clean crisp finish.  It does have a malty flavor, but no sweet.  I don't remember any hop flavor or aroma.

That would be pretty difficult since, often times (flameout or dry hop) the aroma additions add 0 IBU's.

That is what I did today.  I have lost 5 or 6 afternoons at Zum Uerige, 0.25 liters at a time.

What Denny posted is what I remember the guy who was shoveling grain told me as I was on my way back from the mens room (the mash dumps to the floor right by there).  Pils, Cara-maltz, farbemaltz (color malt).  Pearle, Hallertau, Spalt.  I did the 4 step mash today.

I used Kai's water profile.  I have come 3/4's of the way to Zum Uerige, and I hope this nails it.

I guess the problem is that you don't know what you start with. Although I know the city water profile of Duesseldorf I don't know what the water profile for Zum Uerige is. Supposedly they have a deep well for their water.

Your recipe looks good.  I'm thinking your FG will be lower than 1.017, which is a good thing, if I recall the body of this beer is medium to medium light.  Your water may be a bit soft, but I think you should give it a try.

I'm thinking that might be a last resort, especially if I can't get any info on the Dusseldorf water profile.

I guess I'm on the hook for that ;)

The idea of using the Duesseldorf city water is that it seems to be suitable for brewing Altbiers and therefore I assume that a number of Altbier breweries use it. I meant to publis it as a water recipe but haven't done that yet. But you can find it here as I used it as an example:

http://braukaiser.com/wiki/index.php?title=Building_brewing_water_with_dissolved_chalk#Calculating_the_salt_additions

If you don't dissolve the chalk you'll have to double the amount of chalk you add since it is less potent in neutralizing the malt acidity when not dissolved with CO2.

I was also playing with the addition of a new feature to my spreadsheet. This would allow you to specify a target water profile and weights for the particular ions. Then it calculates an error between the current profile and the target profile. Using the solver in Excel or OpenOffice you can then determine what salt additions would work best to match that profile. But it didn't work as expected with the OpenOffice solver and I haven't tried Excel yet.

Kai...I was checking out your website last night and in particular the water treatment page.

So dissolving regular ground chalk...calcium carbonate into my Poland spring water will get me closer to a Dusseldorf water profile.

I guess I'll need to calculate how much based on my current CaCO3 and the targeted amount using your spreadsheet.

I'll have to find some time this weekend to look it over.

Thanks for you help.

You are The King of all Imperial Beer Geeks!  ;D

My hat's off to you Kai.
