Good day to all,
I'm about to move up to all grain brewing and before i start i want to make sure my water profile is right for the mash. I'm looking at brewing Pale Ales with a desired SRM of about 6-10. I know the water in San Antonio is pretty hard with a high RA. I have a water softener but I don't plan on using any of that water since it will be high in sodium, so I plan on diluting the regular tap water with RO. I've used John Palmer's excel sheet to calculate how much dilution I'd have to do to get a target RA. turns out 70% RO water will give me an RA of about 51 and a SRM of 9-14. San Antonio also uses chlorine in the water, should i boil it before I dilute or will that impact any of the parameters? Should I also consider using a PH buffer since it's almost 8 here? Here is the 2011 report.
I appreciate any advice that can be given.
Bicarbonate (ppm) 220
Calcium (ppm) 76
Chloride (ppm) 16
Copper (ppm) 0.01
Iron (ppm) 0.007
Magnesium (ppm) 16.6
Manganese (ppm) 0.0003
Nickel (ppm) 0.002
pH 7.7
Sodium (ppm) 11
Sulfate (ppm) 24
Total Alkalinity as Calcium Carbonate (ppm) 218
Total Dissolved Solids (ppm) 311
Total Hardness as Calcium Carbonate (ppm) 183
Hardness as Calcium/Mg (ppm) 250
Zinc (ppm) 0.019
