Altbier Recipe

Yep…LOTs of variations.  Most are too sweet for my tastes, which is why I prefer Zum Uerige.

It’s generally not a good idea to use a city profile.  How do you know how or if they treat the water?

I don’t know. I was just reading about that in the water knowledge section.

I don’t match water profiles exactly and this is my first time using a city profile as a ‘guide’. I normally just shoot to match S04 and bump up my Ca as needed which is always necessary for my water. Using CaCl naturally brings up my Cl which is not an issue. I can go with the Amber bitter profile for 30 more ppm of SO4 otherwise the difference is minimal for my adjustments.

FWIW, I use Amber Bitter for alt.  Comes out great for the style of alt I like.

Denny-
Is the chocolate simply for color contribution- wondering if some sinamar vs. the roast.

I use 2 oz dehusked carafa ii with good results. I think it adds just a bit of complexity without noticeable roast.

Big time.  I would add that in my estimation, it is Zum Uerige’s application of hops that set them apart as Jeff mentioned, “an outlier” in term of bitterness moreso than a dramatically different grist compared to others in Dusseldorf.

yeah i wouldnt worry about 2oz contributing roast-just curious if it added anything other than color. i have sinamar and 2oz would be good color contribution with all the other malt.

FWIW, I used ~ 2 oz Carafa III last time I brewed that. Came out nice.

Simply for color.  I use sinamar in mine.

ok that’s what i expected.just wanted to make sure i wasnt missing some secret.

40IBU seem reasonable- or too much?

Not too much at all. Here’s the last version of that I did. Zum Uerige is kind of an outlier compared to some - bitterness is fairly high.

OG 1.050

96.1% Pils
2.4% Caramunich
1.5% Carafa III

19.9 IBU HM - 60 min
15.1 IBU Perle - 60 min
14.7 IBU Spalt - 20 min

WY1007 -  hold @ 60F for 3 days, slowly ramp

Mash 150/ 75 mins

Ok makes sense. Pretty much what I plugged in- minus carafa and 97% Pils 3% caramunich with 2oz sinamar.

For my tastes it’s at the low end.

High end is ?

For my taste around 50 to 55.

That Zum Uerige recipe I use works out to 49.7 IBU BTW.

Yeah I tweaked my hop amounts to line up and at about 50…rolling with that. I’m using wlp029

Interesting, I have a “kolsch” fermenting on WY1007 German Ale “Alt” yeast.
