Water profile for kolsch?

[RGeats]

Hi,

Brewing my first AG kolsch tomorrow and thinking about water profiles and what options I've got with my water and additions.

My water is as below:
50ppm Ca
8ppm Na
24ppm Cl
16ppm SO4
166ppm Alk
Not sure about Mg

Have a britta filter which will get the Ca down to 25ppm.

I have gypsum, calcium chloride and CRS to play with.

I know it should be fairly soft for the style, but also thinking when using CRS I'll push up Cl and SO4. Not sure if that's a problem.

Maybe just use the filtered water, adjust the Alk right down, then balance the SO4 and Cl, aim for Ca of around 50ppm?

Any suggestions welcome.

Thanks

I would probably skip the filter, reduce alkalinity to about 20 - 30 ppm and leave it at that. I might be tempted to raise the calcium a little, to maybe 75 ppm or thereabouts with calcium chloride.
