I worked it a few different ways in the spreadsheet and this is what I arrive at using 4 gallons of distilled water for the mash:
15.4 grams calcium sulfate
1 gram calcium chloride (only because I was shooting for the 35 ppm Chloride in the screen shot)
1.2 grams Pickling Lime
Which results in:
Ca: 297
SO4: 619
Cl: 35
TH: 743
Mash pH: 5.2
I've used up to 350 ppm Sulfate in an IPA before and it was fantastic-- my best one to date. I guess other people have used more and liked it. So why not?
But here's an alternative. This is probably a bad way of doing things. I suppose the acid would start to impart flavor at some point:
8.8 grams Calcium Sulfate
0.7 grams Calcium Chloride
4.0 grams Pickling Lime
6.8ml Lactic Acid to bring mash pH down to 5.2
Resulting in:
Ca: 290
SO4: 493
Cl: 35
TH: 727
Mash pH: 5.2
Either way, if I brew this beer I will not pay attention to the hardness of 750. I'm just going to raise sulfates up to about 350 and get the pH to settle in on the lower end of things (5.2 or 5.3)
