I know there are people out there who do this. So I'll ask the question.
If I know I have very soft water (low hardness, but high initial pH) and efforts to brew brown ales come out tasting a bit harsh or acidic, how much either chalk or gypsum would I add to a 5 gallon batch to start to increase the hardness?
No, I don't have a useful water report. We had a massive flood with Irene and the local water supply is all fubar at the moment.
I also want the hops to shine through a bit more. Anyway, if I was to experiment, how much of either chalk or gypsum would you start adding?
