water profile for kolsh/ dusseldorf alt
« on: October 23, 2012, 02:36:05 PM »
I am going to brew a kolsh this weekend and a Dusseldorf alt the following weekend. i want to take a stab at treating my own water for both, to gain more control of the style of my beers.  I have been searching the web for the water profile of koln, germany and what i got seems a little high for kolsh.  the brand i like Sunner seems like it would use a softer water.  Also, i have read that the traditional brewers either use their own wells, or mix softer water with the water from the city.  does anybody have a link, insight, or water profile for both these styles?

Something like this:

Ca = 50   
Mg = 5   
Na = 5   
SO4= 55   Cl=70   
HC03=0   

The point is that you need 50 ppm of Calcium for the yeast...and as little of everything else as possible.  Keep sulfate below chloride for malty emphasis.
