Water Profile for a Düsseldorf Alt?

[Spartan1979]

I did a search, but didn't find anything.

I recently bought an RO system. I'm going brew my Altbier recipe for my next batch and was looking for recommendations for a water profile for that beer.

Thanks.

Try half a tsp of Calcium chloride and half a tsp of gypsum in 5 gallons of RO water. Shouldn't need to do much more than that. Use perhaps 1% sauermalz.

Thanks, I'll start with that.
