You want the water analysis? It's not going to say much ('cos there ain't much to say):
I'm not about to chuck any "AMS" in it. But I do use phosphoric acid when I'm feeling like unnecessarily faffing about (0.41mL was the calculated amount that went into 60L for sparging my last brew). If anyone needs to know how to measure out quantities like that ...
Nice water for making lager.
No it's flaming not! Try making a Dortmunder, Helles, Bock, Dunkel or a schwarzbier, all 'lagers' but not made with water with nothing in it!!
I've said it before, and I'll say it again even the Czch pilsner brewers do not use their water 'as is', even back in the late 80's they were adding calcium chloride and gypsum. Not to extreme levels granted, but often quite a bit higher than you might expect.
The quality of my Bohemian pilsners certainly improved when I stopped using low mineral content liquor and actually started adding 60-70mg/l of calcium to the liquor.
