I'm one of those guys and want to quit.
I'm brewing next Friday, so I probably don't have enough time to get a report from Ward Labs.
But, I have a brand new toy (a PH meter) and an old toy (a HTH water testing kit). Today, I did a sample test:
Total Hardness: 60 ppm
Total Alkalinity: 60 ppm
It's good tasting water. The local microbrew doesn't do much to theirs. (At least that's what they told me).
Usually, I start with about 7 gallons of mash strike water, and 14 gallons of HLT sparge water.
If you were brewing a Pilsener, what would you add? How about for a Black? An amber? and so on.
I don't want to fine tune it too much. I just want to know what stuff to have on hand, so I can add until the PH is right.
I hope it's not too much more complicated than that. Ball park estimate, that's all.
